This command will use the tr tool to translate all lowercase letters in the testfile to uppercase letters and write the output to the uppercase file. The first argument ‘[a-z]’ specifies the set of characters to be replaced, and the second argument ‘[A-Z]’ specifies the set of characters to replace with. The ‘<’ symbol redirects the input from the testfile, and the ‘>’ symbol redirects the output to the uppercase file12.

To run a script file, the user needs to have execute permission on the file. The command chmod u+x /home/user/script.sh (A) will grant execute permission to the owner of the file, which is the user who created it. The other commands will not give execute permission to the user, and therefore will not allow the script to run properly. References:
