I am plumb stumped on this one.
What I need to be doing is to extract all the words that have only 3 letters to the word per line. So only lines that have 3 characters per line.
I have read teh tutorial here at linuxjunior and plus my two textbooks plus my two personal unix books that i have bought and after the full day of banging my head with grep and such I am no where futher than where i started this morning.
So just so you have idea what Im talking about.
Say my file consist of these words.
The only output i want to see are the words.
I can't seem to accomplish this at all from the CL.
Edit: One other question, I often see this result when doing commands, I will type command hit enter and it will return with this...
What does that mean? I can't find any reference on this.
