When a script can recurse at most one time, do you still call it recursive? I'm not sure either. We use UUOC to mean "unnecessary use of cat". Maybe we need UUOR to go with it? How about this alternative..,
well im not talking about recursivity!
i wish to know how does this work?
vino has answered your question, correctly as far as I can see. He mentioned that the script is using recursion. And since you used the present tense, wish, it is apparently the recursion that is still confusing you.
Concur with everyone's comment on this part of the code.
Here is mine.
The script is always taking $1 through out and ignoring $2.
I feel 'if' construct is not at all needed there. The code in 'else'
part simply works.
Only thing 'if' part doing is ,
if the script is provided with 2 arguments as files,
override the 2nd file contents with first file.
the second line $0 $2 is going recursive second and last time
leading that to else part.
