Linux specific console command examples

Examples from other pages included. References also included. This document is in the form of "what you want to do" and "how to do it" taken from our old Linux forum with questions from linux users.

change file case UPPERCASE to lowercase in the same directory

The easiest way is this simple command which uses rename:

rename 'y/A-Z/a-z/' *

Another example using tr:

for i in *; do mv $i `echo $i | tr [:upper:] [:lower:]`; done

Shell script example from the old Advanced Shell Operations page

for FILE in *                        # use mv -i to avoid overwriting files
do                                   # uses the tr command to convert case
  mv -i "$FILE" `echo "$FILE" | tr '[A-Z]' '[a-z]'` 2> /dev/null
done
