Delay between two commands in a terminal

[tech291083]

Hi,

How can I know the time or delay between typing two commands in a terminal? Thanks...

A simple work around would be to prefix the two commands with the date command. ie

date; <command1>
date; <command2>

It all depends what you are trying to achieve...

Yeah, what are you doing? Time how long something takes? If that is the case:

Hi,

Thanks. What I am actually looking for is the time gap between the execution of two commands in a terminal for example here are the two separate commands that I am typing

rpm -qi php

rpm -qi mysql

I just want to see if there is any facility within Linux to for the user to know the execution time of commands and the time gap between them all for the sake of curiosity. Thanks

Hmm, perhaps doing something like:

time command_a && time command_b

or

make a bash script of the list of commands and time that.
