Hey Bakunin! Hi MadeinGermany!

Thanks a lot you guys for your interventions!

@Bakunin:
I knew that declaring the variable so that it can be used elsewhere. However, in the course I'm taking they didn't extend on the value added of it. But I will look KornShell up now thanks to your intervention!
I see that you used local (which I had not seen yet) rather than declare (this was the one I knew about): Any particular reason? Regarding the "-i" I guess it stands for integer?

I loved your comment regarding indexes! You're right the clearer the better! Same for the comment... I'll give your option a try and see how it works for me.

@Bakunin@MadeinGermany:
About sed|grep|awk you must be both right! To tell you the truth, I haven't got to the grep and sed sections yet. I tried some grep from lines I found on the web and as for the sed: I literally copied and pasted it to my script from the web (someone was trying to get rid of the same thing).

Let me keep on going with my Bash course and I'll come back with an update better version.

Thanks again to you both and have a good one!

EDIT: Just tried with the few changes you suggested and for some reason my terminal returns "local: can only be used in a function" and there is definitely no function in my script ... Smilie

I will try using declare, what do you think?

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep  options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
