Is bash compatible with other shells?

hi,

If I wrote a bash script and change the #!/bin/bash to one of these

#!/bin/csh
#!/bin/tcsh
#!/bin/ksh
#!/bin/zsh
..
After installing that other shell will it work? eg. variables, for loops and etc.

The basic concepts are the same, but the implementation differs, otherwise there would only be one shell..

I think I'll stick to bash since all my scripts use functions, variables, for loops that bash understands. Besides, bash is the universal language in many distros by default.

It took me a long time to grasp bash and to learn another shell with different variations is just to much.

appreciated chrism01

Yeah, bash is the default shell in Linux for non-root anyway.
You may find some system scripts use sh (POSIX shell).

I'd also point out that ksh is very similar to bash and certainly used to be the most common default on (non-Linux) Unix systems.
NB: that's talking about the shell built-in cmds, not the external cmds you can call like eg awk, sed etc.
