We've found that it does not handle the -f flag correctly: # Works % zfgrep RELEASE /etc/motd FreeBSD 12.1-RELEASE-p3 GENERIC=20 # Hangs reading from stdin % echo RELEASE > /tmp/0 % zfgrep -f /tmp/0 /etc/motd /etc/motd:FreeBSD 12.1-RELEASE-p3 GENERIC ^Z Suspended leviathan 89 % ps t PID TT STAT TIME COMMAND 11249 4 Ss 0:00.11 -csh (csh) 12190 4 T 0:00.00 /bin/sh /usr/bin/zfgrep -f /tmp/0 /etc/motd 12191 4 T 0:00.00 /usr/bin/zcat -f - 12192 4 T 0:00.00 grep -F -f /tmp/0 -- /etc/motd - 12193 4 R+ 0:00.00 ps t The problem is when -f is used there is no command line pattern and the wra= pper script incorrectly uses the first non-flag argument as a pattern and incorrectly decides we want to read from stdin. Meanwhile grep is invoked w= ith the pattern (really the target file) and a '-'. In then outputs any matches= and hangs, reading from stdin. Here's the most minimal patch I could develop in two minutes. --=20 You are receiving this mail because: You are the assignee for the bug.=
