With #!/bin/bash aka shebang, you declare the script to be bash.
By starting the very same script with tcsh ./script.sh, you overwrite the bash-shebang to be tcsh.
So if the script fails beeing executed by itself, with a bash-shebang, it is not bash.
Changing the shebang to #!/bin/tcsh should do the trick.
This way, if executable flag is set, it can also be executed like:
Code:
./script.sh
/path/to/script.sh
For most scripts you'll find either none or .sh file extension. .sh in this scenario usualy just means 'shell', and that script should contain a shebang, otherwise it simply assumes to be the same shell as the current environment shell.
Know that many, if not all, distro's have /bin/sh symlinked to their specific default shell.
Which in most cases could be either: bash, dash, ksh or zsh.
So going with #!/bin/sh can result in unexpected behaviour when the script is shared.
Scripts without a shebang, should then have their shell/-name as extension, eg: .bash .dash .tcsh
When sharing, most forums to not support 'variant' file extensions to attach, and limit scripts to ".sh", which therefor requires scripts to have the proper shebang set.
