How To Run a Script In Linux

by

There are several ways to run a script in Linux, depending on the type of script and the desired execution environment. Here are a few examples:

  1. To run a shell script, you can make the script executable by running chmod +x script_name.sh and then execute the script by running ./script_name.sh.
  2. To run a Python script, you can use the command python script_name.py. If you have multiple versions of Python installed, you may need to use python3 script_name.py to run the script with Python 3.
  3. To run a script as a background process, you can use the nohup command. For example, nohup python script_name.py &
  4. To run a script on startup, you can put your script in the init.d folder, and create a symlink to it in the rc.d folder.
  5. To run a script as a cron job, you can use the crontab command. Edit the crontab file by running crontab -e and add a new line to schedule the script.

It’s important to note that the script should have the appropriate permissions to run. You can check the permission by running ls -l script_name.sh command and you should see -rwxrwxrwx or -rwxr-xr-x in the output. And also make sure the script is written in correct format and all the commands are working as expected.
