How can I grep through files whose name begins with `-`? I've tried this. grep -r thanks * slave-iv grep: invalid option -- '@' Usage: grep [OPTION]... PATTERN [FILE]... Try `grep --help' for more information. Here's what the directory looks like. They're log files from pidgin. ls -1 -100000139702926@chat.facebook.com -100001138571192@chat.facebook.com -1021869012@chat.facebook.com -12120618@chat.facebook.com -1251570038@chat.facebook.com -1269333626@chat.facebook.com -1394365872@chat.facebook.com -1657581332@chat.facebook.com -211203163@chat.facebook.com -505152641@chat.facebook.com -549333601@chat.facebook.com -557177029@chat.facebook.com -573222477@chat.facebook.com -584051302@chat.facebook.com -65000319@chat.facebook.com -663869224@chat.facebook.com -664953132@chat.facebook.com -755682783@chat.facebook.com
