Question:
I am writing some command line tools to manipulate a large number of text files. How can I pass commandline arguments?Answer:
The command line can be read with @ARGV |  | |
#!/usr/bin/perl $numArgs = $#ARGV + 1; print "$numArgs command-line arguments.\n"; foreach $argnum (0 .. $#ARGV) { print "@ARGV[$argnum]\n"; } | ||

Doesn't address what happens if there are no args provided.

Doesn't address what to do with the arguments once you read them
| ||
| ||
|
if no args then it is -1+1=0....
| ||

Wasn't it explained in beginner's HOWTO on
 http://perl.org? | ||
| ||
|
It's probably going to work anyway, but shouldn't it be $ARGV[ $argnum]?
| ||
| ||
|
please RTFM

Don't pay attention to the haters. This is exactly what I needed. Short & right to the point. THANKS!
