To run a shell script without changing the file access permission, you can use the bash command followed by the -c option and the name of the script file.
For example, if the script file is named script.sh, you can run it using the following command:
bash -c script.sh
This will execute the script using the bash shell, without requiring you to change the file access permissions.
Alternatively, you can use the sh command to run the script. For example:
sh script.sh
This will run the script using the sh shell, which is usually a symbolic link to the bash shell.
It's important to note that the bash and sh commands will only work if the script file is written in a shell language that is supported by the bash or sh shells. For example, if the script file is written in the python language, you will need to use the python command to run it.
It's also worth noting that the bash and sh commands are just two of many different command interpreters that are available on a Linux system. Depending on the script file and the language it is written in, you may need to use a different command interpreter to run it.
For example, if the script file is written in the perl language, you can run it using the perl command:
perl script.pl
If the script file is written in the python language, you can run it using the python command:
python script.py
It's a good idea to include the shebang (#!) line at the top of the script file to specify the command interpreter that should be used to run the script. This will allow you to run the script simply by specifying the script file on the command line, without needing to specify the command interpreter. For example:
./script.sh
