Writing a script for ash?
- by rumtscho
My VPN is behaving funny sometimes, and I have to restart it often. I wanted to write a script which does that for me. It doesn't have to be anything fancy, just a shortcut for the commands I have to type into the terminal. More specifically: it will look at the running processes. If it finds a running vpnc process, it will kill it. Then it will start vpnc.
I've written bash scripts of similar complexity, but now I don't have a bash, only an ash. Until now, the only difference I noticed is that there are much less commands available, but then, I don't use it very often. So I have some questions.
Is writing ash scripts different
than writing bash scripts?
Is there something specific to
consider when doing it?
When the script is ready, how can I
deploy it? For bash, I just put
the executable file under /usr/lib
and run it by typing the file name
into the command line, will this
work with ash?
Are there any special pitfalls to
watch out for in the script I want
to write? I think that the killing
process part may get hairy, if I
write something that kills the wrong
process, but even then running the
script shouldn't break anything
permanently, right?
