This script converts all .wav files in the current directory and its subdirectories to .opus format, using either a Windows command-line script or a Bash translation. The script can also be modified to simply echo the file paths instead of performing the conversion.

Code Breakdown

Windows Command-Line Script

for /r %%v in (*.wav) do opusenc "%%v" "%%~dpv%%~nv.opus"

This is a Windows command-line script that loops through all .wav files in the current directory and its subdirectories.

• for /r is used to recursively iterate through files in the current directory and its subdirectories.
• %%v is the loop variable, which takes the value of each file name during each iteration.
• opusenc is the command used to convert .wav files to .opus format.
• "%%v" is the input file path, and "%%~dpv%%~nv.opus" is the output file path, where:
  • %%~dpv gets the drive letter and directory path of the file.
  • %%~nv gets the file name without the extension.

Bash Translation

for i in $(find. -iname '*.wav'); do opusenc "$i" "${i%.wav}".opus; done

This is the equivalent Bash script for the above Windows command-line script.

• find. -iname '*.wav' is used to find all .wav files in the current directory and its subdirectories.
• for i in... loops over the files found.
• ${i%.wav} gets the file name without the extension.
• opusenc is called with the original file path ($i) and the output file path (${i%.wav}.opus).

Echo Command

for i in $(find. -iname '*.wav'); do echo "$i"; done

This script does the same as the previous one but instead of converting the files, it simply echoes the file paths.

• The echo command is used to print the file path to the console.
