Can command output be redirect to file and screen?

[Guest_imported]

I would like to grab the output of a command and save it to a file as well as displaying it on the screen (which it does by default), is this possible? I was able to get one or the other but not both.

 

[MikeLacey]

like this

ls -l | tee a_file.txt

displays on screen and saves in a_file.txt Mike

Is that a haiku?
I never could get the hang
of writing those things.

Here's a function I wrote to do just that.

just set a value for LOG_FILE

Write () # Display a message on screen and log to a file
# usage: Write "[Your message here]"
{
MESSAGE="$1"
eval "echo \"$MESSAGE\""|tee -a $LOG_FILE
}

# Test Run
Write "Hello There!"
