So ganz dürfen manchmal auch nicht weg, wie folgendes zeigt:

eis # echo abcdef | grep -q "\-\-"
/usr/bin/in.grep: warning: stray \ before -

eis # echo abcdef | grep -q "--"
Usage: in.grep [OPTION]... PATTERNS [FILE]...
Try 'in.grep --help' for more information.

eis # echo abcdef | grep -q "\--"
#
