Making that a bit more flexible (note this is hacked together and only works for files in your current directory that have a three letter extension):

Code: Select all

#!/bin/bash
file="a1b2c3b4pp987.txt"
mv $file ${file: -9}

Or more flexible, letting you run the command with the name of file you want to rename as an argument (so "./scriptname a1b2c3b4pp987.txt"):

Code: Select all

#!/bin/bash
mv $1 ${1: -9}

Or if you want to do that for all .txt files in the current directory, just run the following one command

Code: Select all

for file in *.txt; do mv $file ${file: -9}; done
