all.

I have the following exemple code:

#!/bin/bash
echo "[33[01;32m green 33[01;37m]"
echo "[33[01;31m red 33[01;37m]"

When I run this script locally, I get the correct output color.

But if I copy to another host over scp and run it with "ssh avadmin@10.224.1.6 "sudo sh color-test.sh"" the script will print the code instead of the color.

Should I have any considerations when running script remotely?

The behaviour of

echo '33'

Depends on the implementation and/or the environment.

With UNIX-compliant implementations, it outputs a ESC character followed by NL, in some others, it outputs 33 followed by NL. Some support a -e option for those 33 escape sequences to be expanded.

Your script has a #! /bin/bash she-bang, but you're running the script as sh the-script, so sh interprets it, not bash.

On most systems, bash's echo builtin doesn't expand x sequences by default. It only does so when the xpg_echo option is enabled or by using the -e option (unless both the xpg_echo and posix options have been enabled).

Probably your local sh implementation is a UNIX-compliant one in that regard (like dash, or bash compiled with the xpg_echo option enabled by default), but the one on the remote server is not (like bash).

If you want a portable and reliable behaviour, use printf instead:

printf '[33[01;32m green 33[01;37m]n'
printf '[33[01;31m red 33[01;37m]n'
