4.10. Fixed grep (grep –F and fgrep)

The fgrep command behaves like grep, but does not recognize any regular expression metacharacters as being special. All characters represent only themselves. A caret is simply a caret, a dollar sign is a dollar sign, and so forth. With the –F option, GNU grep behaves exactly the same as fgrep.

Example 4.51.

% fgrep '[A-Z]****[0-9]..$5.00' file      or

% grep -F '[A-Z]****[0-9]..$5.00' file

EXPLANATION

Finds all lines in the file containing the literal string [A–Z]****[0–9]..$5.00. All characters are treated as themselves. There are no special characters.
