File System Commands on Cisco IOS XR Software
This chapter describes the Cisco IOS XR software commands used to manage file systems.
CautionThe commands in this chapter should not be used to access or modify any Cisco IOS XR software or configuration files. Use only the documented commands for installing and configuring the router. Modifying, deleting, or moving configuration or software package files using the manual commands described in this chapter is not required and can result in router downtime, loss of service, and a corrupted database.
cd
To change the present working directory, use the cd command in EXEC mode.
cd [filesystem:]
Syntax Description
filesystem:
(Optional) Location of the new present working directory. Include the file system alias for the filesystem argument, followed by a colon, and, optionally, the name of a directory.
Defaults
The default file directory is disk0:/usr.
Command Modes
EXEC
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.
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/RP0/CPU0:router# cd harddisk:RP/0/RP0/CPU0:router# pwdharddisk: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.

Syntax Description
Defaults
No default behavior or values
Command Modes
EXEC
Administration EXECCommand History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.
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:
•
•
•
•
The following characters cannot be used in filenames:
" ( ) * , / : < > ? \ |The maximum length allowed by the Cisco CRS-1 router for a filename is 254 characters including the path. If a filename longer than 254 characters is specified, the filename is truncated to 254 characters.
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 keywords location all.
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
Table 28 describes the network protocols supported by Cisco IOS XR software.
Additional usage guidelines are in the following sections:
•
Invalid Combinations of Source and Destination
Some combinations of source and destination are invalid. Specifically, you cannot copy the following:
•
•
Using TFTP
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 | location all]
Example:
RP/0/RP0/CPU0:router# copy tftp://1.1.1.1/images/crs_software.pie disk1:
Note
Using FTP
FTP servers require a username and password for each client request. Cisco IOS XR software sends the first valid username in the following list:
1.
The syntax is as follows:
copy ftp://username:password@hostname or ipaddress/directory-path/pie-name target-device [location node-id | location all]
Example:
RP/0/RP0/CPU0:router# copy ftp://john:secret@10.1.1.1/images/crs_software.pie disk1:2.
3.
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.
Using rcp
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:
1.
2.
3.
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 Rtr1ip 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.
Table 29 shows the syntax and example for the copy command when used with FTP, rcp, and TFTP network servers.
Using xml-schema
Use the xml-schema keyword to obtain the most up-to-date XML schemas (.xsd files) from the router. This 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.
Copying to the Running Configuration
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 option 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 configuaration failed command.
Task ID
Examples
The following example shows how to copy a file from a FTP server to disk1:
RP/0/RP0/CPU0:router# copy ftp://john:secret@10.1.1.1/images/comp-crs-full.pie disk1:Related Commands

Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.
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 squeeze 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
In addition to removing deleted files, the squeeze 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 squeeze command.
Rewriting flash memory space during the squeeze operation may take several minutes.

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.
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 undelete 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:Related Commands
unmount
To render a media device safe to be removed, use the unmount command in EXEC or administration EXEC mode.
unmount filesystem: [location node-id] [undo]
