Apologies to list moderator, I attempted to subscribe to the list but vger's majordomo doesn't seem to like gmail. Anyway: The --separator and --columns long options in util-linux-2.21.2 and in a git clone from 5 minutes ago, don't work: # Short options OK: $ echo foobar | column -s x foobar $ echo foobar | column -c 10 foobar # Long options bad: $ echo foobar | column --separator=x column: option '--separator' doesn't allow an argument $ echo foobar | column --separator x Segmentation fault $ echo foobar | column --columns 10 column: bad columns width value: '(null)': Invalid argument $ echo foobar | column --columns=10 column: option '--columns' doesn't allow an argument Looks like a simple case of missing has_arg flag in the "struct option" initialization for these two options. The patch just adds the flag. I haven't done thorough testing of the patched code, but it seems to work OK and it no longer segfaults or tries to dereference a null pointer.
