[SOLVED] Grep help

I have a lot of work getting comfortable with grep.

I am trying to display just the line that has temp1 from sensors output.

This does not work.

grep "temp1" sensors

Hi there,

Is sensors a file or a command (sounds like the latter)? If it's a command, the correct syntax is:

sensors | grep "temp1"

If it's a file, can you provide a sample of it's contents?

you still did not learn: saying "does not work" does not help. Try to explain what's wrong, what is the expected result and what's happened instead.
also (as it was asked): what is that sensors? Is this a command, a script, a file or what? Where is it from (How it was created/downloaded/installed)?

Thanks cliford.

I did not state what sensors was because every distro I have used has it or it is available.
