Assigning values to 2 variables within for loop
Hi All,

Is it possible to grep for two files and assign their names to two separate variables with for loop? I am doing the below currently:

Code:
if [ $FLAG = 0 ]
   then
        for fname in $( cd $dirA ; ls -tr | grep "^Ucountry_file$")
        do
              InFile=$dirA/$fname
              OutFile=$dirB/$fname.processed
                        :
                        :
                        :
               more lines of code
        done
fi

fname in the for loop here holds the name of the Ucountry_file. Likewise, in the same $dirA, there is another file called Rcountry_file. I want to grep for that as well and assign to another variable using the same for loop. Can it be done?

Thanks in advance.

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.
