Access files in a folder

Hello All,


I wanted to do this ...

while(<*.pl>){
print $_;
}


I got "BEGIN failed--compilation"

Am I using something that is old?

Try:

{
local @ARGV = glob( '*.pl' );
while( <> ){
print $_;
}
}

See:
perldoc -f glob
perldoc -f local
perldoc perlvar and search for /\@ARGV/

If you want that in a script, use File::Find and open each file and pass the
file handle.

There is nothing wrong with that. Please show your complete program -
there must be something else in the file that is causing the compilation
error.

Thanks Rob ... It worked. Shawn thanks so much.

I found out that the problem was from my little box Nanonote... It has a
light weight Perl. When I switched to real thing it worked.

Shawn,

Yours will print the content of each file... while mine will list only their
names.

Yes, sometimes people want the contents printed but end up printing the
list. I wasn't sure what you wanted and since your version looked good
for printing the list, I showed how to print the contents.
