How do I remove all .pyc files from a project?
BashBash Problem Overview
I've renamed some files in a fairly large project and want to remove the .pyc files they've left behind. I tried the bash script:
rm -r *.pyc
But that doesn't recurse through the folders as I thought it would. What am I doing wrong?
Bash Solutions
Solution 1 - Bash
find . -name "*.pyc" -exec rm -f {} \;
Solution 2 - Bash
find . -name '*.pyc' -delete
Surely the simplest.
Solution 3 - Bash
Add to your ~/.bashrc:
pyclean () {
find . -type f -name "*.py[co]" -delete
find . -type d -name "__pycache__" -delete
}
This removes all .pyc and .pyo files, and __pycache__ directories. It's also very fast.
Usage is simply:
$ cd /path/to/directory
$ pyclean
Solution 4 - Bash
In current version of debian you have pyclean script which is in python-minimal package.
Usage is simple:
pyclean .
Solution 5 - Bash
If you're using bash >=4.0 (or zsh)
rm **/*.pyc
Note that */*.pyc selects all .pyc files in the immediate first-level subdirectories while **/*.pyc recursively scans the whole directory tree. As an example, foo/bar/qux.pyc will be deleted by rm **/*.pyc but not by */*.pyc.
The globstar shell options must be enabled. To enable globstar:
shopt -s globstar
and to check its status:
shopt globstar
Solution 6 - Bash
For windows users:
del /S *.pyc
Solution 7 - Bash
I used to use an alias for that:
$ which pycclean
pycclean is aliased to `find . -name "*.pyc" | xargs -I {} rm -v "{}"'
Solution 8 - Bash
find . -name '*.pyc' -print0 | xargs -0 rm
The find recursively looks for *.pyc files. The xargs takes that list of names and sends it to rm. The -print0 and the -0 tell the two commands to seperate the filenames with null characters. This allows it to work correctly on file names containing spaces, and even a file name containing a new line.
The solution with -exec works, but it spins up a new copy of rm for every file. On a slow system or with a great many files, that'll take too long.
You could also add a couple more args:
find . -iname '*.pyc' -print0 | xargs -0 --no-run-if-empty rm
iname adds case insensitivity, like *.PYC . The no-run-if-empty keeps you from getting an error from rm if you have no such files.
Solution 9 - Bash
$ find . -name '*.pyc' -delete
This is faster than
$ find . -name "*.pyc" -exec rm -rf {} \;
Solution 10 - Bash
Further, people usually want to remove all *.pyc, *.pyo files and __pycache__ directories recursively in the current directory.
Command:
find . | grep -E "(__pycache__|\.pyc|\.pyo$)" | xargs rm -rf
Solution 11 - Bash
Django Extension
> Note: This answer is very specific to Django project that have already been using Django Extension.
python manage.py clean_pyc
The implementation can be viewed in its source code.
Solution 12 - Bash
Just to throw another variant into the mix, you can also use backquotes like this:
rm `find . -name *.pyc`
Solution 13 - Bash
full recursive
ll **/**/*.pyc
rm **/**/*.pyc
Solution 14 - Bash
if you don't want .pyc anymore you can use this single line in a terminal:
export PYTHONDONTWRITEBYTECODE=1
if you change your mind:
unset PYTHONDONTWRITEBYTECODE
Solution 15 - Bash
Now there is a package pyclean on PyPI, which is easy to use, and cross-platform. User just need a simple command line to clean all __pycache__ files in current dir:
pyclean .
Solution 16 - Bash
First run:
find . -type f -name "*.py[c|o]" -exec rm -f {} +
Then add:
export PYTHONDONTWRITEBYTECODE=1
To ~/.profile
Solution 17 - Bash
rm -r recurses into directories, but only the directories you give to rm. It will also delete those directories. One solution is:
for i in $( find . -name *.pyc )
do
rm $i
done
find will find all *.pyc files recursively in the current directory, and the for loop will iterate through the list of files found, removing each one.
Solution 18 - Bash
find . -name "*.pyc"|xargs rm -rf
Solution 19 - Bash
You can run find . -name "*.pyc" -type f -delete.
But use it with precaution. Run first find . -name "*.pyc" -type f to see exactly which files you will remove.
In addition, make sure that -delete is the last argument in your command. If you put it before the -name *.pyc argument, it will delete everything.
Solution 20 - Bash
If you want to delete all the .pyc files from the project folder.
First, you have
cd <path/to/the/folder>
then find all the .pyc file and delete.
find . -name \*.pyc -delete
Solution 21 - Bash
To delete all the python compiled files in current directory.
find . -name "__pycache__"|xargs rm -rf
find . -name "*.pyc"|xargs rm -rf
Solution 22 - Bash
If you want remove all *.pyc files and __pycache__ directories recursively in the current directory:
- with python:
import os
os.popen('find . | grep -E "(__pycache__|\.pyc|\.pyo$)" | xargs rm -rf')
- or manually with terminal or cmd:
find . | grep -E "(__pycache__|\.pyc|\.pyo$)" | xargs rm -rf
