Name

grep — Searches for matching patterns

Synopsis

grep [-c -i -n -v] searchPattern [objectName]

Description

grep searches the named shell object for lines containing a match to the given search pattern. Matching lines are written to standard output. Regular expressions are not currently supported.

If no object is specified on the command line, grep will read from stdin. If stdin is the console, you may type in lines of text. Enter a “.” all by itself at the beginning of a line to finish.

Options

-c

Just prints count of matching lines; with -v, counts non-matching lines

-i

Ignores case when comparing text with search pattern

-n

Shows line numbers of matches found

-v

Shows non-matching lines instead of matching lines

Example

JXTA>grep -i -n dog GroceryList
3:Hot dogs
7:Dog food
JXTA>cat GroceryList | grep -c dog
