utility bc
To implement an arbitrary precision calculator, use the utility bc command in EXEC mode or administration EXEC mode.
Syntax Description
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. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
Use the utility bc command to use the 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:
The bc utility supports the following common programming language constructs:
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 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
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.
Task ID
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
Command Default
If no file is specified, the keyboard input (standard input) is used.
The delimiter is tab.
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. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
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 fields keyword can also be entered using the UNIX-equivalent (-f). To display the UNIX-equivalent syntax online, enter the usage keyword.
Task ID
Examples
In the following example, the utility cut command is entered with the list character-list keyword and argument to display the first 10 characters in each line. The output is from the results of the show version command, which is entered with the pipe (|) character:

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. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
The utility date command displays the internal time and date for the router.
Date Format
Use the format word option to specify the format and content of the displayed date and time. The format is composed of ASCII characters and field descriptors prefaced with %, in a manner similar to a C-language printf() format specifier. In the output, each field descriptor is replaced by its corresponding value; all other characters are copied to the output without change. The format is specified using the following characters:
- %C
Century in 'CC' form. For example: 20
- %y
Year in 'YY' form. For example: 06
- %m
Month in 'MM' form. For example: 08
- %d
Date in 'DD' form. For example: 28
- %H
Hour in 'hh (24 hr.)' form. For example: 18
- %M
Minutes in 'mm' form. For example: 55
- %S
seconds in 'ss' form. For example: 24

Examples
This example shows how to display the router date and time using the utility date command:
RP/0/RSP0/CPU0:router# utility date Fri Aug 04 11:53:38 UTC 2006This example shows how to display the router date and time using a variety of options with the format keyword:
RP/0/RSP0/CPU0:router# utility date format "%y%m%d" 060828 RP/0/RSP0/CPU0:router# utility date format "%y-%m-%d" 06-08-28 RP/0/RSP0/CPU0:router# utility date format "%C%y-%m-%d" 2006-08-28 RP/0/RSP0/CPU0:router# utility date format "%C%y-%m-%d:%H:%M:%S" 2006-08-28:02:09:58 RP/0/RSP0/CPU0:router# utility date format "DATE: %y-%m-%d %nTIME: %H:%M:%S" DATE: 06-09-17 TIME: 12:42:24utility date set
Syntax Description
hh
Specifies the hour in 2-digit numerical format. Range is 00 to23.
mm
Specifies the minutes in 2-digit numerical format. Range is 0 to 59.
SS
Specifies the seconds in 2-digit numerical format. Range is 0 to 59.
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. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
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 the 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:
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.
Task ID
Examples
The following example shows how to set the time using the utility date set command:
RP/0/RSP0/CPU0:router(admin)# utility date set 13:07:00 Fri Sep 15 13:07:00 UTC 2006utility df
To display the amount of disk space available for a directory or file, use the utility df command in EXEC mode or administration EXEC mode.
Syntax Description
WORD
(Optional) UNIX command-line option string. The maximum number of characters is 80.
kbytes
(Optional) (-k) Displays the sizes in 1-K blocks (1024-byte units) instead of the default of 512 byte blocks.

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. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
The grep utility searches files for character patterns using regular expressions and returns all lines that contain that pattern. The utility egrep command uses full regular expressions (expressions using the full set of alphanumeric and special characters) to match the patterns.
The results are displayed to the standard output (terminal screen).
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 count keyword can also be entered using the UNIX-equivalent (-c). To display the UNIX-equivalent syntax online, enter the usage keyword.
