A minimal implementation of the grep utility. It simplies print lines matching a given regex.

Min-grep has the following features:

• Search recursively in a directory
• Print line numbers matching a pattern
• Match case insensitive
• Understand pipes

Nothing else ;-)

It's meant for systems that don't have mechanisms to search files with a given content.

There's no installation. All you need is a Perl environment.

Search recursively all the files under the current directory and print line numbers when a match is found:

perl min-grep -rn "foo" .

Print all lines with floating point numbers:

perl min-grep "\d+.\d+" foo.txt

Input comes from a pipe. Match lines containing the substring 'bar':

echo "FOOBAR" |perl min-grep -i "bar" -
