I am using 2to3 to fix my script library, and it seems to be a command line thing, not a shell thing.
I want to do all files from /home/me/scripts downward, assuming they end in .py. Is there an easy way to do 2to3 -y filename for each file under my folder in the shell?
There's find command:
find /home/me/scripts -iname "*.py" -exec 2to3 {} \;
The -exec argument tell it to execute the command that follows after this argument, which is 2to3 {} in this case. For each file found, {} is replaced by the name of that file.
bash 4 provides a way of doing recursive globbing.
shopt -s globstar
2to3 /home/me/scripts/**/*.py
