Code:
Linux cmslpc10.fnal.gov 2.6.18-274.12.1.el5 #1 SMP Tue Nov 29 11:14:39 EST 2011 x86_64 x86_64 x86_64 GNU/Linux

---------- Post updated 2012-08-18 at 07:28 AM ---------- Previous update was 2012-08-17 at 12:32 PM ----------

Hi,
I am not sure as how shall I go ahead with it. I mean changing the shell or something.

Here is the output of the following command:
Code:
[pooja04@cmslpc10 ~/CondorJobs]$ which sh
/bin/sh
[pooja04@cmslpc10 ~/CondorJobs]$ whereis sh
sh: /bin/sh /usr/share/man/man1p/sh.1p.gz /usr/share/man/man1/sh.1.gz
[pooja04@cmslpc10 ~/CondorJobs]$

I would be really happy if bash scripts can run there. Just to mention, I do use simple bash scripts there. And they work. But this particular one failed.

Thanks
Pooja

OK, let me spell it for you. Literal transcription into bash:
Code:
#!/bin/bash  

TARGETPATH=$2 
Max=3 
Card=card_Data2011AB_Zee_40Ge

#Loop  (no function here)
for i in {0..7} ; do     
    echo "SHELL SCRIPTING ================ $i =============="
    cp $FILE $TARGETPATH
    if [[ $i -eq 0 ]] ; then
         source $TARGETPATH
         echo 'Press [Enter] key to continue...'
         read thisvar
         rm $TARGETPATH
     elif [[ $i -lt $Max ]] ; then
         perl -i.bak -pe 's/(file)(\d{1,})/$1 . (1 + $2)/ge' $Card
         cp $FILE $TARGETPATH
         source $TARGETPATH
         echo 'Press [Enter] key to continue...'
         read thisvar
         rm $TARGETPATH
       elif [[ $i -eq $Max ]] ; then
            perl -pi.bak -e 's/file/file1/g' $Card
            echo "Its About To Terminate...Enjoy Scripting"
      fi
done

Fixed that for you.

Not all Bourne shells are BASH. BASH is a Bourne shell, with extended features that a generic Bourne shell doesn't have -- like arrays, and functions.

There is also more than one version of BASH. Some of them support more things than others. Only very new versions of BASH have direct regex support for example, i.e. [[ "$STRING" =~ /regex/ ]] so don't use that if you don't know your system will have have BASH and a very new bash at that.

Avoiding BASH features will make your scripts much closer to generic Bourne scripts, which should theoretically work equally well in bash, sh, and ksh. You may be surprised how much you can do without them; a lot of things people use arrays for can be replaced with set --, proper use of the read command and IFS, or simple string-splitting, for instance.
