Page 73: Understanding Regular Expressions
Understanding the Command-Line Interface Understanding Regular Expressions Understanding Regular Expressions The Cisco NX-OS software supports regular expressions for searching and filtering in CLI output, such as the show commands. Regular expressions are case sensitive and allow for complex matching requirements. Special Characters You can also use other keyboard characters (such as ! or ~) as single-character patterns, but certain keyboard characters have special meanings when used in regular expressions.
Page 74: Anchoring
Searching and Filtering show Command Output Often, the output from show commands can be lengthy and cumbersome. The Cisco NX-OS software provides the means to search and filter the output so that you can easily locate information. The searching and filtering options follow a pipe character (|) at the end of the show command.
Page 75: Filtering And Searching Keywords
Include lines that match Filtering and Searching Keywords The Cisco NX-OS CLI provides a set of keywords that you can use with the show commands to search and filter the command output. This table lists the keywords for filtering and searching the CLI output.
Page 76: Diff Utility
Removes diff temporary files from all sessions (past and present sessions) of all users. 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.
