hello jalindar

well to write that script you need the following:
1. unix (or call it linux if you prefer!)
2. a shell (bash, ksh, csh or zsh)
3. sed
4. awk
5. grep
6. cut
7. uniq
8. scripting knowledge

OR

clusterssh or dsh (distributed shell)

OR

a configuration management tool like puppet or bcfg2 or the like

Hi Marafa,

Thanks replied to my post. I know that you said languages I need, but my problem is I tried to change configuration file using shell script, awk, sed, but didnt success.
My problem is how to replace the value of variable(s) in config file(s) through script?
for ex.
consider following from main.cf
default_process_limit=10
I want to change this value to 20 or 30 through script.
