How do I remove a specific extension from files recursively using a bash script

Question

I'm trying to find a bash script that will recursively look for files with a .bx extension, and remove this extension. The filenames are in no particular format (some are hidden files with "." prefix, some have spaces in the name, etc.), and not all files have this extension.

I'm not sure how to find each file with the .bx extension (in and below my cwd) and remove it. Thanks for the help!

Answer 1

find . -name '*.bx' -type f | while read NAME ; do mv "${NAME}" "${NAME%.bx}" ; done

Answer 2

Assuming you are in the folder from where you want to do this

find . -name "*.bx" -print0 | xargs -0 rename .bx ""

Answer 3

find -name "*.bx" -print0 | xargs -0 rename 's/\.bx//'

Answer 4

Bash 4+

shopt -s globstar
shopt -s nullglob
shopt -s dotglob

for file in **/*.bx
do
  mv "$file" "${file%.bx}"
done

Answer 5

for blah in *.bx ; do mv ${blah} ${blah%%.bx}

Answer 6

Here is another version which does the following:

1. Finds out files based on $old_ext variable (right now set to .bx) in and below cwd, stores them in $files
2. Replaces those files' extension to nothing (or something new depending on $new_ext variable, currently set to .xyz)

The script uses dirname and basename to find out file-path and file-name respectively.

#!/bin/bash

old_ext=".bx"
new_ext=".xyz"

files=$(find ./ -name "*${old_ext}")

for file in $files
do
    file_name=$(basename $file $old_ext)
    file_path=$(dirname $file)
    new_file=${file_path}/${file_name}${new_ext}

    #echo "$file --> $new_file"
    mv "$file"    "$new_file"
done
