This is my 'automated radio recording' python script.

To run this script, python /path/path/ebs.py Name 1190(length)

And when I type it on terminal, it works perfectly. But When I do it on Crontab.

40 6 * * 1-6 python /Users/myname/Dropbox/ebs/ebs.py Ears 10

I have error report like this.

Traceback (most recent call last):
  File "ebs.py", line 31, in <module>
    recording()
  File "ebs.py", line 23, in recording
    p = subprocess.Popen(rtmpdump)

  • Most probably related to cron offering having a more restricted PATH to the environment. Try to specify the absolute path to the program and it should work – Ricardo Cárdenes Nov 25 '15 at 05:18
  • try replacing with absolute paths (like `/bin/rm` for `rm`) – Ayush Nov 25 '15 at 05:21
  • Oops I forgot to write my cron code. 40 6 * * 1-6 python /Users/myname/Dropbox/ebs/ebs.py Ears 10 – HeungBeom Kim Nov 25 '15 at 05:28
  • @HeungBeomKim That doesn't matter. We're talking about the paths of the programs you are running *within* your script (ffmpeg, rtmpdump, rm). rm should be ok, because it is in /bin, but the others are not being found in the PATH. And yes, it *may* be different for a command line that comes from a login and for a program run from the cron. Trust me, happened to me too many times. – Ricardo Cárdenes Nov 25 '15 at 06:13

Try being specific about where your version of python is and where the location of your script is in the crontab entry.

30,0 * * * * /path/to/python /path/to/your/script
