Usage guidelines
To quickly locate certain lines in the output from a display command, you can use regular
expressions to filter the output, and display a number before each output line. For more information
about regular expressions, see
Fundamentals Configuration Guide .
If you specify multiple filter conditions, the system displays the output lines that meet all the
conditions.
A line number is a 5-character string and is typically followed by a colon (:). If you specify both the
by-linenum and begin regular-expression options, a line number might be followed by a
colon or a hyphen (-).
•
Colon —The line matches the regular expression.
•
Hyphen —The line does not match the regular expression.
