Beginner, don't yell please! I have looked at and downloaded a number of the bash tutorials and have a lot of unanswered questions still.

I'm trying to sort out Barry's mageia2ppm to handle a number of possibilities for a field in the one list as it's changed in mageia2 where files in the file lists can now have an inclusion of:
mga1, still used mageia 1 files,
mga2, new mageia2 compiled files,
or mgac, the talked about Mageia 'cauldron' file directory, which is their "here be dragons" level files. Currently mageia 2 beta lives there!

Task Problem No1.

I want to setup the following

Variable MAGEIA_VERSION = '1' or '2' or 'c' (the digits 1, 2, or the lowercase letter c) only.

so it should look like?

Code:

#!/bin/bash

MAGEIA_VERSION= 1||2||c



that doesn't look right?

Can I have some guidance please![/code]

I'm guessing you're also new to programming in general. Smile And I don't think Bash is a good "first" programming language, but since you're at it, you may want to look into arrays.

Anyway, I'm not a Bash expert, I'm sure others will be able to offer more efficient help in learning how to do what you wanna do with it. I wish you all the best on your journey! Smile

scsijon,

Several possibilities - here's two....

Code:
if grep -Eq  '1|2|c'  <<<$MAGEIA_VERSION; then echo ok; fi

And-

 case $MAGEIA_VERSION  in   -1|2|c) echo ok  ;;  esac



Cheers,
s

Code:
case "$MAGEIAVERSION" in
  1)v1_function;;
  2)v2_function;;
  c)vc_function;;
  *)echo "$MAGEIAVERSION" not supported && exit;;
esac
or if they are all use the same function you can simply
Code:
case "$MAGEIAVERSION" in
  1|2|c)the_function;;
  *)echo "$MAGEIAVERSION" not supported && exit;;
esac

no, dawg, just little use for a decade or two down at this level! Use to do everything by scripting back in the '70's and 80's. Brain doesn't get used with information, information gets lost or overwritten!

Perfecto technosaurus, that first bit of code should deal with two problems at once, thanks. I'm trying to sort out the mageia2ppm file converter problem (t=75739 and t=56867) as it will become a major problem soon as mageia2 is due out as release on 14th May. I'm using it for qtpuppy!

thanks to all
