Bash thyself!

Example

A sample pipeline with gstspectrum

Final pipeline:

./gstspectrum input.wav | \
| ./selectmaxcolumn.py \
| ./sortranges.py \
| ./compact.py \
| ./editwithsox.py $1 \
| bash

Bash

Useful things:

BASH counting loops
BASH math substitution
sprintf for filenames

Extra

Using Python's argparse is great for making flexible command line tools.
