Bash Shell: cat/cp and cut/awk
I'm writing a bash shell script which go through a large file and generate a large file.
Does anyone know which is faster ?
1. cut VS awk for stripping certain fields.
2. cat old-file > new-file VS cp old-file new-file.
Also, can anyone give a general direction on how to write bash shell script that run efficiently ?
Like what is generall bad things to do...
I know it is best to use built-in commands for bash but is there any other ?
How about using many pipes and command substitution using backup quotes ?

I keep seeing this post sitting here and I keep wondering how to reply.. but I just keep thinking 'Is there really going to be *any* appreciable difference?' my instincts tell me there isn't.
