Quickly creating a shell script

Suppose you want to create and run a short script. It’s often faster not to bother opening up a text editor. Instead, use shell history to write a file, then chmod and execute it:



$ cat > /tmp/me.py

#!/usr/bin/env python

print('hello world')

$ chmod a+x !$

chmod a+x /tmp/me.py

$ !$

/tmp/me.py

hello world

$
