time: Time "ls".

try on your machine
The command "time ls" is used to measure the amount of time taken by the "ls" command to execute.
The "ls" command is used to list the files and directories in a directory. By adding the "time" command before "ls," it allows you to measure the time taken by the "ls" command to complete the listing.
The output of the "time" command, when used with another command like "ls," provides the following information:
- "real": The actual elapsed time taken by the command to execute, including any time spent waiting for resources or other processes.
- "user": The amount of CPU time used in user-space by the command.
- "sys": The amount of CPU time used in kernel-space by the command.
This can help you analyze the performance of the "ls" command or compare the execution times of different commands or options.
