Grep And Egrep Utilities - Cisco Nexus 9000 Series Configuration Manual

grep and egrep Utilities

The Cisco NX-OS software creates temporary files for the most current output for a show command for all
current and previous users sessions. You can remove these temporary files using the diff-clean command.
diff-clean [all-sessions | all-users]
By default, the diff-clean command removes the temporary files for the current user's active session. The
all-sessions keyword removes temporary files for all past and present sessions for the current user. The
all-users keyword removes temporary files for all past and present sessions for the all users.
grep and egrep Utilities
You can use the Global Regular Expression Print (grep) and Extended grep (egrep) command-line utilities to
filter the show command output.
The grep and egrep syntax is as follows:
{grep | egrep} [count] [ignore-case] [invert-match] [line-exp] [line-number] [next lines] [prev lines]
[word-exp] expression}]
This table lists the grep and egrep parameters.
