Deleting files in Linux for bulky folders

1.)man rm
2.)rm -rf

Well second command above will work but it will delete all files and directories inside TXNPROC. If you want to be selective, you'll have to add some additional commands.

Delete the whole folder, then re-create it!

You could learn shell scripting and write a script to sort all the files fairly easily. as far as deleting them all rm -rf is the way to go.
