For example, the keyword universal can also be entered using the UNIX-equivalent (-u). To display the UNIX-equivalent syntax online, enter the keyword usage.
utility bc
To implement an arbitrary precision calculator, use the utility bc command in EXEC mode or administration EXEC mode.
utility bc [file input-file]
Syntax Description
file input-file |
(Optional) Specifies the text file containing commands and function definitions to be interpreted by the bc utility. After all files have been read, the bc utility reads input from the standard input (keyboard). If no files are specified, then only the standard input (keyboard) is used. The input-file syntax is: device:[/directory-path]/filename Include the alias for the device argument, followed by a colon, and, optionally, the name of a directory. The possible devices are: •bootflash:—Uses a file from the bootflash: file system (Cisco XR 12000 Series Routers only). •compactflash:—Uses a file from the compactflash: file system (Cisco XR 12000 Series Routers only) •compactflasha:—Uses a file from compactflasha: file system partition (Cisco XR 12000 Series Routers only) •disk0:—Uses a file from disk0: file system. •disk0a:—Uses a file from disk0a: file system partition. •disk1:—Uses a file from disk1: file system. •disk1a:—Uses a file from disk1a: file system partition. •flash:—Uses a file from the flash: file system. The flash: keyword is alias for bootflash: (Cisco XR 12000 Series Routers only). •ftp:—Uses a file from an FTP network server. The syntax is ftp:[[[//username [:password]@] location]/directory]/filename. •harddisk:—Uses a file from the hard disk drive file system (if present). •harddiska:—Uses a file from the hard disk partition (if present). •nvram:—Uses a file from the nvram: file system. •ipv4—Uses a file from an IPv4 access list or prefix list. •ipv6—Uses a file from an IPv6 access list or prefix list. •rcp:—Uses a file from a remote copy protocol (rcp) network server. The syntax is rcp:[[[//username@]location]/directory]/filename. •tftp:—Uses a file from a TFTP network server. The syntax is tftp:[[//location]/directory]/filename.

If you need assistance with your task group assignment, contact your system administrator. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of Cisco IOS XR System Security Configuration Guide.
Use the utility bc command to use the an interactive, programmable calculator that supports a complete set of control structures, including functions. The utility first processes any specified files, and then reads input from the keyboard (standard input).
Input files (and standard input) are ASCII text files containing sequences of bc statements to be executed.
Note The bc utility uses the bc programming language, an arbitrary precision calculator language with syntax similar to the C programming language. The bc utility does not support character or string manipulation.
The bc utility supports:
•26 functions
•26 simple variables
•26 array variables (up to 2048 elements per array).
The bc utility supports the following common programming language constructs:
•"if", "while", and "for" statements
•User-defined functions with parameters
•Local variables
Information About Supported Network Protocols
In the syntax for the ftp:, rcp:, and tftp: network protocols, the location is either an IP address or a hostname. The filename is specified relative to the directory used for file transfers.
When no device is specified, the current directory is used. To view the current directory, enter the pwd command.
Table 102 describes the network protocols supported by the Cisco IOS XR software.
Table 102 Network Protocols Supported by the Cisco IOS XR software
|
|
|
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 |
Rcp is a protocol that allows users to copy files to and from a file system residing on a remote host or server on the network. Rcp uses TCP to ensure the reliable delivery of data. Rcp downloads require a username. |
Examples
In the following example, the utility bc command is used to execute the be statements contained in the ASCII text file exp.txt:
RP/0/RP0/CPU0:router# utility bc file disk0:/usr/exp.txt
utility cut
To extract selected characters or fields from standard input or from a file, use the utility cut command in EXEC mode or administration EXEC mode.
utility cut {{list character-list | fields field-list [nodelim] [delimiter delimiter-character] | WORD} [file input-file] | usage}
Syntax Description
list character-list |
(-c) Cuts out the characters that are located on each line as specified with the character-list argument. The character-list argument specifies the character positions or range of the characters to be cut. •Use a comma (,) to indicate more than one character. For example, utility list 1,2,5 outputs the first, second, and fifth characters. •Use a dash (-) to indicate a range. For example, utility list 1-64 outputs the first 64 characters of each line, utility list 5- outputs the fifth character to the end of the line. Note Lines are separated by a delimiter. The default delimiter is tab. |
fields field-list |
(-f) Cuts out the fields (lines) as indicated with the field-list argument. The list argument specifies the field numbers or ranges. For example, utility field 2,9 outputs the second and ninth fields, utility field 1-3 outputs the first three fields, utility list -6 outputs the first six fields. Note The fields indicated by the list argument are assumed to be separated in the file by a delimiter character. The default delimiter is tab. Use the delimiter delimiter option to specify a delimiter character. Lines without field delimiters are processed unless the nodelim keyword is specified. |
nodelim |
(Optional) (-s) Ignores lines with no delimiter. Use this optional keyword when the fields list keyword and argument is specified, |
delimiter delimiter-character |
(Optional) (-d) Specifies an alternative delimiter to indicate the end of each field. Replace the delimiter-character argument with the character used as the delimiter. |
WORD |
(Optional) UNIX command-line option string. The maximum number of characters is 80. |
file input-file |
(Optional) Storage device and directory path of the text file used instead of the standard input (keyboard input). The input-file syntax is: device:[/directory-path]/filename Include the alias for the device argument, followed by a colon, and, optionally, the name of a directory. Use the online help system to display the available storage devices and network protocols. |
usage |
(Optional) Displays the UNIX options supported by this command. |
Defaults

Usage Guidelines
To use this command, your Cisco IOS XR software system administrator must assign you to a user group associated with a task group that includes the corresponding command task IDs. If you need assistance with your task group assignment, contact your system administrator. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of Cisco IOS XR System Security Configuration Guide.
The utility cut command cuts out columns, fields, or characters displayed from standard input or from a file.
Use the fields field-list keyword and argument if the fields vary in length from line to line. (The lines must be separated by a delimiter character.) By default, the field delimiter character is the Tab key. Use the delimiter delimiter-character keyword and argument to specify a different delimiter.
Use the list character-list keyword and argument only if the fields are of a fixed length. Replace the character-list argument with the character positions to be extracted.
For the character-list argument, use a comma (,) to indicate more than one character, or use a dash (-) to indicate a range. For example, utility list 1,2,5 outputs the first, second, and fifth characters, utility list 1-64 outputs the first 64 characters of each line, utility list 5- outputs the fifth character to the end of the line.
You can also use the cut utility as a filter. If no files are specified, the keyboard input (standard input) is used.
Note Keywords are entered using the displayed syntax, or with UNIX-equivalent syntax. The UNIX-equivalent syntax is displayed in parentheses () in the syntax description. For example, the keyword fields can also be entered using the UNIX-equivalent (-f). To display the UNIX-equivalent syntax online, enter the keyword usage.

Usage Guidelines
To use this command, your Cisco IOS XR software system administrator must assign you to a user group associated with a task group that includes the corresponding command task IDs. If you need assistance with your task group assignment, contact your system administrator. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of Cisco IOS XR System Security Configuration Guide.
A colon (:) is required between the entry for hour, minutes, and seconds.
Note Generally, if the system is synchronized by a valid outside timing mechanism, such as a Network Time Protocol (NTP) clock source, or if you have a networking device with calendar capability, you need not set the software clock. Use the date command or clock set command if no other time sources are available.
Note To manually copy the hardware clock (calendar) settings into the software clock, use the clock read-calendar command in EXEC mode.
By default, the system makes a "slow adjustment" if the new time is in the range of the following:
•-2.5 minutes + old time
•5 minutes + old time
In a slow adjustment, the clock speed increases by less than 100 percent or decreases by less than 50 percent over a period of time from 1 second to 5 minutes until the clock catches up with the new time. This slow adjustment does not cause major discontinuities in the time flow. Use the -S0 option to disable the slow adjustment.
Examples
The following example shows how to set the time using the utility date set command:
RP/0/RP0/CPU0:router(admin)# utility date set 13:07:00
Fri Sep 15 13:07:00 UTC 2006
