    Problem with Crontab and a speedtest script

    Hi everybody, i've a problem with the periodic execution of a speedtest script through crontab.
    I've wrote the following script invoking the speedtest-cli script, the script is the following:
    speed_script.sh
    Code:
    #!/bin/shdate >> /home/user/speedtest.log
    speedtest-cli --simple >> /home/user/speedtest.log
    echo "" >> /home/user/speedtest.log
    Then i've edited the crontab configuration file (crontab -e) with the following line, in order to test and write down the network speed every half an hour:
    Code:
    0,30 * * * * /home/user/speed_script.sh
    So, the resulting file speedtest.log only contains the date of the tests, without the internet speed results.

    If I run the script manually from terminal, the script runs correctly and the speedtest.log contains the date anche the speedtest output.
    Where's the mistake?
    Thanks everybody...

    This is the output file with crontab:
    Code:
    Tue Apr 29 11:00:53 CEST 2014
    Download: 4.84 Mbits/s
    Upload: 0.47 Mbits/s
    
    Tue Apr 29 11:30:45 CEST 2014
    Download: 3.89 Mbits/s
    Upload: 0.38 Mbits/s
    And this with the manual execution:
    Code:
    Tue Apr 29 11:47:11 CEST 2014
    
    Tue Apr 29 11:51:32 CEST 2014

    P.S. Sorry for my english, but it's not my native language...

    Where is the "speedtest-cli" executable and is that in the execution path of whatever runs the cron jobs? Ddi you try to give a full path to it in the script?

    Re: Problem with Crontab and a speedtest script

    First thing: I began to study and use crontab only yesterday, so I know very little .
    I installed speedtest via pip using the command pip install speedtest-cli so i don't know where the executable is. I tried to look it up in /usr/bin but unsuccessfully.
    Then i use locate speedtest-cli and the result is /usr/local/bin/speedtest-cli.So i modified the script including the full path of speedtest-cli... and now seems to work!
    Now i do some tests...
    For now thank you so much!
