Linux Shells by Example

3.4. Recursive grep (rgrep)

Unlike the members of the grep family, Linux's rgrep can recursively descend a directory tree. Rgrep has a number of command line options and supports the same metacharacters as regular grep (grep-R). See page713 in Appendix A for a complete description of rgrep, or type rgrep-? for online help. (Not supported on regular versions of UNIX.)

Example 3.34.

% 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.
