Hello caba_jones,

Welcome to forums. While seeing your code I think you need to rename all txt files into your present directory. If this is the case then following may help you in same.
Code:
for file in *.txt; do echo mv $file ${file%_*}$(date +%Y%m%d%H%m)".txt"; done

Above code will write the move command, so if you are ok with this then you could remove echoin bold above code and could change the .txt files to as per your need.
EDIT: Adding a non-one liner form of solution above too.
Code:
for file in *.txt
do
   echo mv $file ${file%_*}$(date +%Y%m%d%H%m)".txt"
done

Thanks,
R. Singh

Hello caba_jones,

Yes, it will rename the files in current folder where you are running the script or command as mentioned above. In case we want it to take care of a folder where we are not currently in then you should mention the complete path of those .txt files as follows.
Code:
for file in /tmp/test/*.txt       ######Basically mention complete path of .txt files in here.
do
   echo mv $file ${file%_*}$(date +%Y%m%d%H%m)".txt"
done

As mentioned before you could remove echo from your code in case you are happy with the printed commands by echo.

Thanks,
R. Singh

Code:
for file in ${DPATH}/*.txt.pgp; do  mv ${test}/${FN} ${FN%_*}$(date +%Y%m%d%H%m)"test.txt.pgp" ; done  
mv: cannot access (the above path)

i am not able to move the files even though i have 777 permission,can you please let me know any other reasons not able to move the file.
