grep

[Daniel Schade]

Dear gnu.org Team,

I have useed grep to search for double minus in a string and grep told me an
error, take a look to the samples

address@hidden echo "Test --" | grep -i '--'
Usage: grep [OPTION]... PATTERN [FILE]...
Try `grep --help' for more information.


address@hidden echo "Test --" | grep -i ' --'
Test --


address@hidden grep --version
grep (GNU grep) 2.5.1

Best regards Daniel
