[Novalug] Unix script help request

[Kevin Starkey]

Hi all,

My Linux experience (meager as it is) is finally starting to be 
applicable at my job (mainframe programmer). We just started using a 
Unix file server on the mainframe and occasionally we run into an issue 
to solve and I volunteered to tackle this one. The issue is, I might 
have 0, 1, or > 1 files in a directory with the same name pattern of 
"EBPV************.out.xml" and one of these files might be the one I'm 
looking for, or it might not. I need to identify a particular string 
inside of the file, and if it matches, then I want to add an 'S' to the 
start of the name (SEBPV....).

Below is the start of a script that I hope is close to what I need, but 
I need to add "grep" and a conditional statement where I only do the 
renaming if the grep finds what I'm looking for, but I'm not sure how to 
code that part (this is my first script).

---------------------------------------------------------------------------------------------------
#!/bin/bash

# Change to directory
cd /proj/preed/output

#Get all needed files in current directory
originalFiles=$(ls EBPV*.out.xml)

# Loop through all files and do your changes
for loopFile in $originalFiles
do
# Create your new filename including the extension
mv $loopFile S$loopFile
done
---------------------------------------------------------------------------------------------------

I need to somehow add:

grep $loopfile "<TRANS_CDE>RSCF"

and only if it's found then I want to do the "mv ...." (renaming).

Any help would be greatly appreciated.

Thanks,
Kevin.
