Subject: flock: use more useful example in flock.1
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c348d9346ae60b78a03d6dcd964e23fb40a625df;p=util-linux

flock: use more useful example in flock.1

The example in the man page does not prevent concurrent execution, as it
obtains a shared lock. More useful is taking an exclusive lock, i.e.
remove "-s".
Additionally, IMO most people want the script to exit when the lock
cannot be acquired, so adding "-n".
