Re: [Help-bash] bash to csh converter?

[Steven Ford]

Mun,

I am also curious about the details here.

What kind of issues were you running into using the bash scripts from csh?
Are they meant to create aliases or set environment variables?
How many lines of bash code do you have that rewriting them is not
practical?

If the bash scripts have functions that they need to use, you could make
those functions accessible as individual bash scripts or modify your bash
scripts to call a function passed as an argument.

Something like this:

#!/bin/sh

function foo {
  echo foo
}

function bar {
  echo bar
}

$@

Would allow you to invoke the bash functions like ./script.sh foo with
minimal modification to the bash script by adding $@ to the bottom. That is
if the functions are what you need.

Hope this is helpful.

Regards,

Steve
