NAME
       grep - Display lines matching a pattern

SYNTAX
	 list [component] "|" grep [ [option | pattern] ... ]
	 show [component] "|" grep [ [option | pattern] ... ]
	   options:
	     -A [integer]
	     -B [integer]
	     -C [integer]
	     -E
	     -G
	     -P
	     -c
	     -e [pattern]
	     -i
	     -m [integer]
	     -n
	     -o
	     -v
	     -w
	     -x Note: Each option must be followed by a space.

       Note: tmsh treats any argument that is not preceded by a supported option, and does not begin with a hyphen, as a search
       pattern preceded by -e.

DESCRIPTION
       You can use grep to filter the output generated by the commands list (configuration settings) and show (statistics and
       runtime status). You must type the character | before the grep specification. You can use multiple filters chained
       together.

EXAMPLES
       The following examples show how to use the grep utility in tmsh.

       list ltm node | grep "^10\.2"
       list ltm virtual | grep -i seattle
       list ltm virtual | grep -i abc | grep -i ab | grep -i a

OPTIONS
       -A   Display the specified number of lines of context after matching lines.

       -B   Display the specified number of lines of context before matching lines.

       -C   Display the specified number of lines of context before and after matching lines.

       -E   Interpret patterns as extended regular expressions.

       -G   Interpret patterns as basic regular expressions.

       -P   Interpret patterns as Perl regular expressions.

       -c   Display a count of the lines that match. If -v is specified the number of non-matching lines is displayed.

       -e   Specify a pattern. This is useful to protect against patterns beginning with a hyphen.

       -i   Case insensitive search.

       -m   Stop reading input after the specified number of matching lines. If -c is specified the count will not exceed the
	    value specified for -m. If -v is specified grep will stop after finding the specified number of non-matching lines.

       -n   Prefix each line of output with the line number relative to the input.

       -o   Show only the part of a matching line that matches the pattern.

       -v   Invert the sense of matching, to select non-matching lines.

       -w   Select only those  lines  containing  matches  that  form  whole words.  The  test is that the matching substring must
	    either be at the beginning of the line, or preceded  by  a	non-word  constituent  character. Similarly, it must be
	    either at the end of the line or followed by a non-word constituent character.  Word-constituent  characters are
	    letters, digits, and the underscore.

       -x   Select only those matches that exactly match the whole line.
