shell scripting guides?

Grife · 03-20-2007, 11:32 AM

I'd like to learn some shell scripting to speed up several tasks I find myself repeating over and over again, like copying several directories with update attribute to external harddrive. Could you recommend any good starting points in the internet?

Try "Bash Guide for Beginners" and "Advanced Bash Programming" (bash is the shell most distros use).

Those mentioned by pljvaldez are the best. For a beginner, these may be useful too:

You can find a list of good resources on the web at http://cfaj.freeshell.org/shell/resources.shtml.

which shell?
hint:

#!/bin/ksh -u
#!/bin/bash -u

or

typset -nounset # same as -u but more explicit placement

will cause an error if you try to use an unbound variable. This
can save a lot of pain when you have mis-typed a variable name.
