Using the Pipe ( | ) Symbol to Filter Junos Command Output
The Junos OS enables you to filter command output by adding the pipe ( | ) symbol when you enter a command.
For example:
user@host> show rip neighbor ?Possible completions: <[Enter]> Execute this command <name> Name of RIP neighbor instance Name of RIP instance logical-system Name of logical system, or 'all' | Pipe through a command
The following example lists the filters that can be used with the pipe symbol ( | ):
user@host> show rip neighbor | ?Possible completions: count Count occurrences display Show additional kinds of information except Show only text that does not match a pattern find Search for first occurrence of pattern hold Hold text without exiting the --More-- prompt last Display end of output only match Show only text that matches a pattern no-more Don't paginate output request Make system-level requests resolve Resolve IP addresses save Save output text to file trim Trim specified number of columns from start of line
For the show configuration command only, an additional compare filter is available:
user@host> show configuration | ?Possible completions: compare Compare configuration changes with prior version ...
You can enter any of the pipe filters in conjunction. For example:
user@host> command | match regular-expression | save filename
 | Note: This topic describes only the filters that can be used for operational mode command output. For information about filters that can be used in configuration mode, see the Junos OS System Basics Configuration Guide. |
