I hope to draw on the knowledge of those who know far more about scripting than I. I have two files, F1 and F2, where F2 is located in a sub-directory of F1. I need to output a new file, F3, that has the entire contents of F1, followed by the contents of F2 but excluding the first line of F2 (the contents obtained by doing 'tail +2 subdir/F2'). My attempts so far have been fruitless, so any help would be gratefully received.

cat "F1" > "F3"
tail +2 "subdir/F2" >> "F3"
This will write F1 into F3, and then append the tail output. It's called output redirection.

Is there any reason not to use
cp F1 F3for the first step? Commented Jan 18, 2012 at 15:38 -
@DennisWilliamson I'm not sure what file attributes
cppreserves by default. But you're right,cp "F1" "F3"would also work.– Daniel Beck ♦Commented Jan 18, 2012 at 15:40
You can also use command grouping to obtain a one-liner:
{ cat F1; sed 1d dir/F2; } > F3
