Question

Write a Bourne Shell function called “psuser” that will display the processes running on the process status list for the System Administrator / Super User, redirecting the output to the filename psuser.out.

Answer 1

To create a Bourne Shell function called 'psuser' that lists processes for the Super User and redirects output to a file, use the ps command with specific flags to filter for root processes, redirecting the output using the '>' operator.

Step-by-step explanation:

The question involves writing a Bourne Shell function named psuser which has the aim of showing the processes currently running on the system for the Super User. This function should also redirect the output to a file called psuser.out. Here is a simple example of what the function might look like:

psuser() {
ps -U root -u root u > psuser.out
}

This function uses the ps command to display the processes run by the Super User, commonly known as 'root'. The '-U' flag specifies the effective user ID to be listed, and the '-u' flag repeats this for user names. The 'u' option tells 'ps' to provide detailed user-oriented information. The output is then redirected into the file named psuser.out.
