Usage Guidelines To use this command, you must be in a user group associated with a task group that includes the proper
task IDs.
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).
Keywords are entered using the displayed syntax, or with UNIX-equivalent syntax. The
Note
UNIX-equivalent syntax is displayed in parentheses () in the syntax description. For example, the
keyword count can also be entered using the UNIX-equivalent (-c). To display the UNIX-equivalent
syntax online, enter the keyword usage.

In the following example, the utility egrep command is used to locate the regular expression "uptime".

7:router uptime is 5 days, 19 hours, 27 minutes

this example, all lines with "adm" are displayed. The * character is used as a wildcard.
