Linux Avoid overwriting backup file when multiple entries need to replace in one file input from another

Hello,
I have been working on script in which search and replace the multiple pattern.


1. update_params.sh read the multiple pattern from input file ParamMapping.txt(old_entry|New_entry) and passing this values one by one to change_text.sh
2. change_text.sh read input from update_params.sh
search files and based upon parameter(search and replace) from update_params.sh generates FileList.lst
for each files in FileList.lst it takes backup(.bkp) and replace the string and update in to new file.


Issue when a same file contain multiple string defined in ParamMapping.txt which is going to be replace, it also replaces the entry in .bkp files which I have to avoid.
I am not able to figure out how to avoid overwriting .bkp file when multiple entries need to replace in one file.

PFA files.


file execution :

Code:
./update_params.sh ParamMapping.txt

Any suggestions will be helpful.....Smilie


Thanks,
Ketan R
