GREP(1) General Commands Manual GREP(1)
grep - search a file for lines containing a given pattern
grep [-elnsv] pattern [file] ...
-e -e pattern is the same as pattern
-c Print a count of lines matched
-i Ignore case
-l Print file names, no lines
-n Print line numbers
-s Status only, no printed output
-v Select lines that do not match
grep mouse file # Find lines in file containing mouse
grep [0-9] file # Print lines containing a digit
Grep searches one or more files (by default, stdin) and selects out all the lines that match the pattern. All the regular expressions
accepted by ed and mined are allowed. In addition, + can be used instead of * to mean 1 or more occurrences, ? can be used to mean 0 or 1
occurrences, and | can be used between two regular expressions to mean either one of them. Parentheses can be used for grouping. If a
match is found, exit status 0 is returned. If no match is found, exit status 1 is returned. If an error is detected, exit status 2 is
cgrep(1), fgrep(1), sed(1), awk(9).
