• Why does my script return 0 when it fails ? Bash, Whisper, ffmpeg

  30 avril 2024, par d-b

  I have a bash script that executes whisper on all sound files in a directory. Whisper uses ffmpeg to decode sound files to a format it can handle. One of the files in the directory was corrupt and caused ffmpeg to fail. The first time I executed my script it returned 1 when it hit that file but when I try to reproduce the error it always returns 0.

  


  Here is the log from the first run when 1 was returned :

soundfile1.opus: Invalid data found when processing input

% echo $?
0


  


  When I try to reproduce the behaviour I have both tried to execute the script as well as just running the actual line of code from the command prompt. The actual script looks like this :

  


  if whisper "$file" >> "${directory}/../${transdir}/${name}.txt"; then
    whispersuccess=$?
    echo "exit code $whispersuccess"
else
    whispersuccess=$?
    echo "exit code: $whispersuccess"


  


  I want it to return ¬0 when something like this happens. How do I achieve this ?

  


• Why does a command in my Bash-script return 0 even when it fails ? Python, Whisper, ffmpeg

  When I try to reproduce the behaviour I have both tried to execute the script as well as just running the actual line of code from the command prompt. The actual script looks like this :

  


  if whisper "$file" >> "${directory}/../${transdir}/${name}.txt"; then
    whispersuccess=$?
    echo "exit code $whispersuccess"
else
    whispersuccess=$?
    echo "exit code: $whispersuccess"


  


  I want it to return ¬0 when something like this happens. How do I achieve this ?
