Running an SPTK command for all the files in a directory

Question

I have the following command to convert a raw file into float

x2x +sf < /raw-en/1.raw > /raw-f/1.f

I need to run it for all the files in the directory "raw-en"

Answer 1

That's a typical use-case for a for loop:

for file in /raw-en/*; do
    x2x +sf < $file > /raw-f/$(basename $file .raw).f
done

Edit: Fixed output directory as noted by @ederollora.

Edit[2]: You should consider using *.raw in the for-loop to suite your use-case (thanks again to @ederollora).

Answer 2

You can loop over the files in the directory:

#!/bin/bash
for filename in /raw-en/*; do
    x2x +sf < "$filename" > /raw-f/"${filename%.*}.f"
done

This should fit your case.
