simple logging functions for bash

Bash Logging

Usage

#!/bin/bash
source /path/to/logging/repo/logging.sh

LOG_LEVEL=DEBUG
log_debug Hello,World!

Note: colors are disabled if standard output is redirected to a file.

Configuration

Two environment variables can be used by the script which imports logging.sh;

LOG_LEVEL=TRACE
TIMESTAMP_FMT=+%Y-%m-$d

Note that these are optional, since the defaults are as follow:

LOG_LEVEL=WARN
TIMESTAMP_FMT=+%Y-%m-$dT%H:%M:%S

If you are on a linux machine, you should use a TIMESTAMP_FMT value with the %N field for nanoseconds. logging.sh uses the date utility, for which the %N is invalid on OSX.
