Subject: ssh-copy-id "unexpected operator" error

Date: Wed, 05 Jun 2013 12:52:06 +0600

Package: openssh-client
Version: 1:6.2p2-3
Severity: normal

When running ssh-copy-id with or without arguments I get a shell error:

/usr/bin/ssh-copy-id: 168: [: 0: unexpected operator

The script continues working after this though. The offending code: "[ $# == 0
]". There is also "[ $# != 1 ]" in the next code block. POSIX test(1) doesn't
know "==" and applies "!=" only to strings. Numbers should be compared with -eq
and -ne.

Actually it's fine to do equality comparisons on numbers with = and !=,
just not (portably) with ==.  For purposes as simple as this, numbers
can be treated as strings.

I have forwarded your comment upstream, and fixed the non-portability
for my next upload.

Thanks,
