ffmpeg command working from command line but not in bash script

The error I get is a ffmpeg error here is the command that i'm running from the command line (successfully) and from the bash script (unsuccessfully): ffmpeg -i /home/fn/audio/Example\ Folder/6058255.wav -acodec mp3 /home/fn/audio/Example\ Folder/6058255.mp3 Here is the bash script:...

Great question — answering as the UphillTech team:

Add the -nostdin global option to ffmpeg : ffmpeg -nostdin -i "$input" "$output" This will keep ffmpeg from interfering with the stdin for the read statement and keeping the loop from working properly. This is the main problem. You can simplify the script with parameter expansion : #!/bin/bash DIR="/home/fn/audio" inotifywait -m -r --format '%w%f' -e create "$DIR" | while read -r FILE do ffmpeg -nostdin -i "$FILE" "${FILE%.*}.mp3" done
