Script to Rename files with a Date suffix to a common filename

I have a requirement where I need to rename a couple of filenames to a fixed filename every week.

To explain better, each week I receive 3 files in the format :

File_ABC_20160822.TXT.pgp
File_DEF_20160822.TXT.pgp
File_GHI_20160822.TXT.pgp

I need to run a small script to rename the files to :

File_ABC.dat
File_DEF.dat
File_GHI.dat

without deleting the original files, since we have to keep a log of delivered files.

The issue is that since the files come with a new date suffix each week, the script would have to pick current system date in YYYYMMDD format.

You can loop over the files names use bash parameter expansion to get the desired name while renaming:

for f in File_*_*.TXT.pgp; do echo cp -i "$f" "${f%_*}.dat"; done

The above will do a Dry-run, for actual action, remove echo:

for f in File_*_*.TXT.pgp; do cp -i "$f" "${f%_*}.dat"; done
