The chmod +x command is used to change the permissions of a file, specifically to make a shell script executable.
Here's what it does:
chmod: This command stands for "change mode" and is used to change the file system modes of files and directories.+x: This option adds the executable permission to the file for the user, group, and others.
For example, if you have a shell script named script.sh, you would run the following command to make it executable:
chmod +x script.sh
After running this command, you can execute the script directly from the terminal by typing:
./script.sh
This is essential for running shell scripts, as they need to have the executable permission set to be executed.
