I saw this: -
-sh: 2: [: -gt: unexpected operator
-sh: 29: [: -gt: unexpected operator
-sh: 2: [: -gt: unexpected operator
-sh: 29: [: -gt: unexpected operator
when logging into an Ubuntu boxen.
I was pretty sure that this'd worked before, but wondered whether my shell was giving me (s)hell ....
I checked what I was currently running: -
echo $SHELL
/bin/sh
which is a flavour of the Bourne Again SHell ( BASH ).
I then checked the /etc/passwd file: -
cat /etc/passwd
hayd:x:12039:12039::/home/hayd:
and realised that I didn't have an explicit shell set.
I upped my authority ( super user do ): -
sudo bash
[sudo] password for hayd:
and then updated my account: -
usermod --shell /bin/bash hayd
Now /etc/passwd looks OK: -
hayd:x:12039:12039::/home/hayd:/bin/bash
and I'm now all good to go: -
echo $SHELL
/bin/bash
