Title: Newbie question: Process entire folder in Terminal
Post by: uge on June 02, 2021, 08:02:02 AM

Hello there,

I'm enjoying using the CDP in Terminal. I would like to know if is possible to use CDP commands with wildcards (*) in order to process entire folders.

Any help with this would be appreciated.

Thanks in advance,

Cheers,

Uge

The idiomatic way to do this is to use the shell scripting facilities. It is a good idea to read up on shell commands (and practice a little before committing to anything serious). Simple commands can be done directly at the prompt, but most of the time you will want to create a text file for your script. Here is an example to copy files to a named subdirectory:

#!/bin/bash
# usage  copyfiles.sh outdir
# copies wave files in current directory to same names in directory outdir
# outdir will be created if not present
# copysfx must be in system PATH

if [ -z $1 ]; then
  echo "usage: ./copyfiles.sh outdir"
  echo "outdir will be created if it does not exist."
  echo
  exit
fi

if [ $1 == "." ]; then
echo "can't copy files into same directory!"
echo
exit
fi

if [ ! -d $1 ]; then
    mkdir $1
fi

for filename in *.wav
do
   copysfx $filename $1/$filename
done

Thanks a lot,

I'll start experimenting with this. Yesterday I was reading a book about UNIX and I was trying some FOR loops with no luck. But this is the key of everything. I'll try this and practice with it.

Thanks again,
