People find the bash a good tool to fulfill miscelaneous tasks. I do also have some nice ones.

The exec trick

To redirect stdout+err to file when non-interactive.

#!/bin/bash

[ -d "$HOME/log" ] || mkdir "$HOME/log"
if [ ! -t 1 ] ; then
    exec >$HOME/log/mylog.log 2>&1
fi

TO-DO: Unclutter from logging … Python Logging
