The current directory contains the following file:
-rwxr-xr-x 1 root root 859688 Feb 7 08:15 test.sh
Given that the file is a valid shell script, how can this script be executed? (Choose TWO correct answers.)
Executing the script can be done using ./test.sh or bash test.sh.
Both methods are valid ways to run a shell script in a Unix-like operating system. The first method, using `./test.sh`, requires the script to be executed from the current directory, while the second method, `bash test.sh`, invokes the script using the Bash shell regardless of the current directory.
This is not a valid command in Unix-like operating systems. The command `run` is not recognized as a built-in or external command for executing scripts. To execute a script, the proper syntax must be used, such as `./` or by invoking the shell directly.
This syntax attempts to execute the script in a subshell and is not appropriate for executing a script directly. Instead, it is used for command substitution, which captures the output of a command rather than executing it as a standalone script. Therefore, this choice does not lead to executing the script.
This command attempts to change the directory to `/test.sh`, which is incorrect because `/test.sh` is a file, not a directory. The `cd` command is used to change directories, and this choice does not execute the script but rather returns an error if `/test.sh` does not exist as a directory.
To execute a shell script, proper command syntax is essential. The two correct methods, `./test.sh` and `bash test.sh`, effectively allow for script execution, while the other choices either misuse command syntax or misinterpret the nature of the file. Understanding how to execute scripts is fundamental for effective shell programming and script management.
