linux上的脚本外壳和solaris上的脚本外壳之间的区别

Question

I want to learn shell scripting and I will use solaris in my work. Is there any difference between shell scripts on linux and shell scripts on solaris?

Answer 1

The difference is not between Linux and Solaris, the difference is between which shell you are using on each: sh, csh, ksh, zsh, bash etc.

When you write a shell script you should always start it with a shebang indicating what shell the script is written for. For example
#!/bin/bash
or
#!/bin/csh

Note shebang also works for scripting in non-shell languages:
#!/usr/bin/perl
#!/usr/bin/python

The bash shell is now commonly available nearly everywhere, and I suggest that's the one you learn if it's available on you Solaris system.
/bin/sh is the POSIX shell and you should learn that, and the differences between it and bash.

ksh is an improvement over sh , as is zsh (but zsh claims it "is a shell designed for interactive use" )

csh is considered evil

These days bash and sh are the ones to learn.

Answer 2

thank you all. What I understood from your replies that I have to learn the bash shell which is compatible with linux and solaris.
