Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
The present working directory is the directory used when EXEC commands that have an optional filesystem argument are entered without that argument. Use the cd command to define the present working directory. For example, when the dir command is entered without specifying the filesystem argument, the files in the present working directory are displayed.
Use the pwd command to display the present working directory.
Use the show filesystem command to display the available storage devices.
Enter the cd command without an argument to return the present working directory to disk0:/usr.
Task ID
Examples
The following example shows how to change the present working directory to the root directory on the hard disk. In this example, the pwd command confirms that the present working directory has changed to the root directory on the hard disk.
RP/0/0/CPU0:router# cd harddisk: RP/0/0/CPU0:router# pwd harddisk:The following example shows how to change the present working directory to the default file directory by specifying the cd command without a location. In this example, the pwd command confirms that the present working directory has changed to the default file directory.
RP/0/0/CPU0:router# cd RP/0/0/CPU0:router# pwd disk0:/usrcfs check
To perform a check of the Configuration File System (CFS), use the cfs check command in EXEC or administration EXEC mode.

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
Source and destination can each be a configuration file, a text file, or a file system. Enter source and destination URL information, usernames, and passwords and issue the copy command. The networking device prompts for any missing information.
The exact format of the source and destination arguments vary according to the file or directory location. Enter the device or network location for the file system type.
Filenames can include the following characters:
! # $ % & ' + 0 1 2 3 4 5 6 7 8 9 ; @ A B C D E F G H I J K L M N O P Q R S T U V W X Y Z [ ] ^ _ a b c d e f g h i j k l m n o p q r s t u v w x y z { } ~
The following characters can be used with the stated limitations:
` needs backslash before this character
– cannot be the first character
. cannot be the last character
= cannot be the filename without other characters
The following characters cannot be used in filenames:
" ( ) * , / : < > ? \ |
To copy a file from a source on the router to a destination on the router, specify a source location node-id and a destination location node-id . To copy the file to all nodes, use the location all keywords.
In the alias syntax for the ftp: , rcp: , and tftp: keywords, the location is either an IP address or a hostname. The filename is specified relative to the directory used for file transfers.
When no alias is specified, the networking device looks for a file in the current directory. To view the current directory, enter the pwd command.
Note
During processing of the copy command, you might see the “C” character. For all files being copied, “C” indicates that the copy process is taking place. The entire copying process might take several minutes and differs from protocol to protocol and from network to network.
Table 1 describes the network protocols supported by Cisco IOS XR software.
Table 1 Network Protocols Supported by Cisco IOS XR Software Prefix
Name
Description
tftp:
Trivial File Transfer Protocol
TFTP is a simplified version of FTP that allows files to be transferred from one computer to another over a network, usually without the use of client authentication (for example, username and password).
ftp:
File Transfer Protocol
FTP is an application protocol, part of the TCP/IP protocol stack, and is used for transferring files between network nodes. FTP requires a username and password.
rcp:
Remote Copy Protocol
The rcp protocol allows users to copy files to and from a file system residing on a remote host or server on the network. The rcp protocol uses TCP to ensure the reliable delivery of data. The rcp protocol downloads require a username.
Additional usage guidelines are in the following sections.
Some combinations of source and destination are invalid. Specifically, you cannot copy the following:
TFTP is a simplified version of FTP that allows files to be transferred from one computer to another over a network, usually without the use of client authentication (for example, username and password).
The syntax is as follows:
copy tftp://hostname /ipaddress/directory-path pie name target-device [location {node-id | all}]
Example:RP/0/0/CPU0:router# copy tftp://1.1.1.1/images/software.pie disk1:
Note
Some Cisco IOS XR images may be larger than 32 MB, and the TFTP services provided by some vendors may not support a file this large. If you do not have access to a TFTP server that supports files larger than 32 MB, download the software image using FTP or rcp as described in the following sections.
FTP servers require a username and password for each client request. Cisco IOS XR software sends the first valid username in the following list:
The username and password specified in the copy command, if a username is specified.
The syntax is as follows:
copy ftp:// username : password @ hostname or ipaddress/directory-path/pie-name target-device [location {node-id | all}]
Example:RP/0/0/CPU0:router# copy ftp://john:secret@10.1.1.1/images/software.pie disk1:An “anonymous” username and password. The anonymous password is “root@ip address,” where “ip address” is the IP address of the local networking device.
A password “username@iosname.domain” formed by the networking device. The variable “username” is the username associated with the current session, “iosname” is the configured hostname, and “domain” is the domain of the networking device.
The username and password must be associated with an account on the FTP server. If you are writing to the network server, the FTP server must be properly configured to accept the FTP write request from the user on the networking device.
If the network server has a directory structure, the configuration file or image is written to or copied from the directory associated with the username on the network server. For example, if the system image resides in the home directory of a user on the network server, specify the name of that user as the remote username.
Refer to the documentation for your FTP server for more details.
The rcp protocol requires a username upon each request. When you copy a configuration file or image between the networking device and an rcp server, the Cisco IOS XR software sends the first valid username in the following list:
The remote username specified in the copy command, if one is specified.
The username set by the rcp client username command, if the command is configured.
The networking device hostname.
For the rcp copy request to process successfully, an account must be defined on the network server for the remote username. If the network administrator of the destination server did not establish an account for the remote username, this command does not run successfully. If the network server has a directory structure, the configuration file or image is written to or copied from the directory associated with the remote username on the network server. For example, if the system image resides in the home directory of a user on the network server, specify the name of that user as the remote username.
If you are writing to the network server, the rcp server must be properly configured to accept the rcp write request from the user on the networking device. For UNIX systems, add an entry to the .rhosts file for the remote user on the rcp server. Suppose the networking device contains the following configuration lines:
hostname Rtr1 ip rcp remote-username User0If the IP address of the networking device translates to company.com, then the .rhosts file for User0 on the rcp server should contain the following line:
company.com Rtr1See the documentation for your rcp server for more details.
If you are using a personal computer as a file server, the computer must support remote shell (rsh) protocol.
Use the xml-schema keyword to obtain the most up-to-date XML schemas (.xsd files) from the router. Using this keyword is useful to prevent the use of outdated schemas in the event that router software updates include schema updates. The tar ball file includes all active schema files. It does not include schemas that are activated by specific package installation envelopes (PIEs) if those PIEs are not installed and activated on the router.
When you use the copy command to copy a configuration file to the running-config destination, the configuration in the file is applied to the running configuration of the system. This is a configuration operation. By default, the copy is carried out in a best-effort manner. This means that if some configuration lines from the file cannot be applied, the remaining configuration is still integrated into the system. In this case, a partial configuration is committed. When the atomic keyword is used, partial configurations are not committed. This means that even if one error occurs in the parsing or committing phase, no changes are made to the system. To view any errors when applying the configuration, use the show configuration failed command.

Before you can use a new flash memory card, you must format it.
Caution
Formatting a storage device deletes all data on that device.
Use the online help ( ? ) function to display the file systems available to be formatted on the router and the formatting options available for a file system.
You cannot format an active boot disk. However, you can format the standby boot disk. Verify that the boot disk you want to format is on the standby RP, then use the format command.
Disk0: and disk1: can be partitioned into two partitions each: disk0: and disk0a:, disk1: and disk1a:. The harddisk: can be partitioned into three partitions: harddisk:, harddiska:, and harddiskb:. The primary partitions are used to store critical data. The secondary partitions are used to store noncritical data.

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
When flash memory is full, you might need to rearrange the files so that the space used by the files marked “deleted” can be reclaimed. (This “squeeze” process is required for linear flash memory cards to make sectors contiguous; the free memory must be in a “block” to be usable.)
When you enter the command, the router copies all valid files to the beginning of flash memory and erases all files marked “deleted.” After the squeeze process is completed, you can write to the reclaimed flash memory space.
Caution
After performing the squeeze process you cannot recover deleted files using the undelete command.
In addition to removing deleted files, the command removes any files that the system has marked as “error.” An error file is created when a file write fails (for example, the device is full). To remove error files, you must use the command.
Rewriting flash memory space during the squeeze operation may take several minutes.
Task ID
Examples
The following example shows how to permanently erase files tagged as “deleted” or “error” on the bootflash file system:

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
For flash file systems, when you delete a file, Cisco IOS XR software simply marks the file as deleted, but it does not erase the file. The command allows you to recover a deleted file on a specified flash memory device. You must undelete a file by its index, because you could have multiple deleted files with the same name. For example, the “deleted” list could contain multiple configuration files with the name router-config. You undelete by index to indicate which of the many router-config files from the list to undelete. Use the dir command to learn the index number of the file you want to undelete.
You cannot undelete a file if a valid (undeleted) file with the same name exists. Instead, you first delete the existing file and then undelete the file you want. For example, if you had an undeleted version of the router-config file and you wanted to use a previous, deleted version instead, you could not simply undelete the previous version by index. You would first delete the existing router-config file and then undelete the previous router-config file by index. You can delete and undelete a file up to 15 times.
On flash file systems, if you try to recover the configuration file pointed to by the CONFIG_FILE environment variable, the system prompts you to confirm recovery of the file. This prompt reminds you that the CONFIG_FILE environment variable points to an undeleted file. To permanently delete all files marked “deleted” on a flash memory device, use the squeeze command.
Task ID
Examples
The following example recovers the deleted file whose index number is 1 on the bootflash file system:
RP/0/0/CPU0:router# undelete 1 bootflash:unmount
To render a media device safe to be removed, use the unmount command in EXEC or administration EXEC mode.
Syntax Description
filesystem: File system to unmount, followed by a colon. Possible values are disk0: , disk1: , harddisk: , compactflash: .
location node-id (Optional) Specifies a node. The node-id argument is expressed in the rack/slot/module notation.
undo (Optional) Remounts the device if it is not removed and reinserted.
