  • How to set crontab in order to run multiple python and a shell scripts ?

    5 janvier 2021, par Alexander Mitsou

    I need to start three python3 scripts and a shell script using crontab. These scripts should run at the same time without any delay. Each script runs exactly for one minute. For instance I have scheduled crontab to run these scripts every 5 minutes.

    


    My problem is that, if I attempt to run each script individually from terminal it executes with no further errors, but using crontab nothing happens.

    


    DISCLAIMER : If I set up the Python3 scripts individually in crontab, they work fine !

    


    Here's my crontab set up :

    


    */5 * * * * cd /home/user/Desktop/ && /usr/bin/python3 script1.py >> report1.log

*/5 * * * * cd /home/user/Desktop/ && /usr/bin/python3 script2.py >> report2.log

*/5 * * * * cd /home/user/Desktop/ && /usr/bin/python3 script3.py >> report3.log

*/5 * * * * cd /home/user/Desktop/ && /usr/bin/sh script4.sh >> report4.log 


    


    In addition I need to mention that the shell script contains this command (FFMPEG) :

    


    #!/bin/bash

parent_dir=`dirname \`pwd\`` 
folder_name="/Data/Webcam" 
new_path=$parent_dir$folder_name  


if [ -d "$new_path" ]; then
    echo "video_audio folder exists..."
else
    echo "Creating video_audio folder in the current directory..."
    mkdir -p -- "$new_path"
    sudo chmod 777 "$new_path"
    echo "Folder created"
    echo
fi

now=$(date +%F) 
now="$( echo -e "$now" | tr  '-' '_'  )"
sub_dir=$new_path'/'$now 

if [ -d "$sub_dir" ]; then
    echo "Date Sub-directory exists..."
    echo
else
    echo "Error: ${sub_dir} not found..."
    echo "Creating date sub-directory..."
    mkdir -p -- "$sub_dir"
    sudo chmod 777 "$sub_dir"
    echo "Date sub-directory created..."
    echo
fi

fname=$(date +%H_%M_%S)".avi"
video_dir=$sub_dir'/'$fname
ffmpeg -f pulse -ac 1 -i default -f v4l2 -i  /dev/video0 -vcodec libx264 -t 00:01:00 $video_dir 


    


    The log file of that script contain the following :

    


    video_audio folder exists...
Date Sub-directory exists...

    Due to the reason that the python files are of the same structure I'm uploading a sample file here :

  • M3U8. Convert all parts to mp4 [closed]

    5 juin 2020, par Zikrulloh Tolibjonov

    My name is Zikrullah. I have the m3u8 file of the serial. 1 m3u8 file contains all parts of the series and all audio languages for the player. The parts in it were saved in ts format for 10 seconds (as far as I understand). When I opened the m3u8 file, it contained a link to other m3u8 files. If I'm not mistaken, these are separate m3u8s for audio languages. but all m3u8 and ts files related to the video are on a other server. I need to upload all the files to my server while keeping them all in order. Of course using php. I'm sorry if I made a mistake. I don't know English well, but I tried :)
