Description Wolfram Schneider freebsd_committer freebsd_triage 2024-04-15 12:59:11 UTC 
man(1) ignores errors from gzip if a file is corrupt. You can see the errors from gzip on stderr, but the exit status of man(1) will be zero.

How to repeat:

$ touch /tmp/bla.1.gz

$ /usr/bin/man /tmp/bla.1.gz >/dev/null; echo $?
gzcat: /tmp/bla.1.gz: unexpected end of file
gzcat: /tmp/bla.1.gz: unexpected end of file
gzcat: /tmp/bla.1.gz: unexpected end of file
0

In case of an error, man(1) should exit with a non-zero status.
