Modify different files at the same time
Hi, I'm having the following problem.
I have some files to modify, between a large number of files.
I thought the following code

PHP Code:
aux2=`grep -l 2.2.17 *`
print "$aux2"
aux3=`ls -l *.ksh | wc -l`
print "$aux3"

while [  $aux3 -ne 0 ]; do
        print "The counter is $aux3"
        #Add the sed here
        aux3=$((aux3-1))
done 
I also thought the basic code for the modify. I have to use a sed :P
But I don't know how to go between the different files in the while. Use the first file in the first loop, the second file in the following loop and so on.
The files are stored in the aux2 variable.

Could you give me any idea

Thanks

zgrep

ZGREP(1)                                                      General Commands Manual                                                     ZGREP(1)

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.
