Remove the encoding line in python files

Posted on 2015-07-22 in Trucs et astuces

When making a python project python 3 only, I decided to delete the lines giving the encoding of the files. All files were in UTF-8 and it is the default encoding in python 3.

I wrote this little script to get the job done.

for file in $(find chsdi/ -name \*.py); do
  # Remove coding line
  sed -i '/^# *-\*- .*coding: utf-8 -\*-/d' $file
  # Remove whitespace line after it if it exists
  if head -n 1 $file | grep '^$'; then
    sed -i '1d' $file
