in the section "check for username" am i going to the next line after reading the current line? coz at the min iam just getting an infinite loop as for some reason the script never exists that for loop. if it doesnt goto the next line how does make i go to thenext line? also is it legal to use exit for like i have in the "check for username".

Your inifinite loop is in the "count the number of files" part of the code which is just before the section of code you thought the loop was in.

You're not reading lines in that bit of code so you never reach a f.AtEndOfStream condition.

yer.
