Hi Tricia.
There's nothing new herem just boiling down the answers that others have
posted:
- system() returns the exit status code of the external program it ran,
not the output. A value of 1 generally indicates success.
- to get the output of an external program, use backticks: `ls -al` rather
than system().
- get into the habit of doing things within Perl if you can. This
increases the chances of your program working on another
system. opendir/readdir/closedir calls will let you build a directory
- use stat() to get extended information about an existing file ( lstat()
will do the same for a link )
HTH,
Rob
