Here’s a neat little bash script that converts all uppercase characters in a filename to lowercase and renames the files. As you know the filenames and URLs on the web are case sensitive. It’s always a good practice to replace spaces with a dash
- and use all lowercase letters in filenames. Here’s the shell script. Two things you need to do:
- Save the following code in a file named preferably ws-ren.sh (web-safe-rename). dot sh means it’s a shell script.
- Give it execute permissions
- Try it somewhere safe
#!/bin/sh # lowerit # convert all file names in the current directory to lower case # only operates on plain files--does not change the name of directories # will ask for verification before overwriting an existing file # first argument should be the current file name # change $1 to `ls` in the next line to rename all files without passing filename as the argument / will automatically take from ls for x in "$1" do if [ ! -f "$x" ]; then echo "$x" 'not found' continue fi lc=`echo "$x" | tr '[A-Z]' '[a-z]' | tr -s '[:space:]' | tr ' ' '-' | tr -cd 'A-Za-z0-9-.'` #echo "$x" | tr '[A-Z]' '[a-z]' | tr -s '[:space:]' | tr ' ' '-' if [ $lc != "$x" ]; then mv -i "$x" "$lc" echo Renamed: "$x" to "$lcn" fi done
With some minimal changes in code you’ll be able to do a mass rename or just a one-off rename by passing the filename as the first parameter. Tada!
Hold on. Can you make this script better?
