I love bash and scripting!!! There’s almost nothing you can’t do with a shell script that would take me forever if I had to write an app to do the same. So here’s another quick tip. To convert text in a file from uppercase to lowercase use the following:
cat FILENAME | tr “[:upper:]” “[:lower:]“
Or to go from lowercase to uppercase:
cat FILENAME | tr “[:lower:]” “[:upper:]“
