Usage: rgrep [-iredblL] regexp filepat ...
regexp = perl regular expression to search
filepat ... = a list of files and directories to be searched or
file patterns to match filenames.
filepat will be interpreted as file or directory name if it exists
as such, and does not contain the metacharacters [ ] ? or *. After
the options -i and -r all filepats will be considered patterns.
rgrep will search all files in any of the directories given (and its
subdirectories) that match any of the filepats, except binary files.
Compressed files will be searched in uncompressed form.
Note: filepats may contain / contrary to find usage.
-b Don't skip binary files.
-i Ignore case, either in the regexp or in filename matching (depending
on the location). Before the regexp only applies to the regexp,
otherwise to the filepats following it.
-r The following filepats are treated as real perl regexps rather than
shell style filename patterns. In this case / is not a special
character, i.e. it is matched by . and matching is not anchored (you
must supply ^ and $ yourself). E.g. a.b matches the file /xa/by/zz.
-l Do follow symbolic links only for files (default is do not follow).
-L Do follow symbolic links for files and directories.
-e Do not interpret following argument as option. Useful if regexp or
filepat starts with a -.
-d Debugging: Give a lot of output on what happens.
-h print this message and exit.
