I've tried adding a path to my file lookup but I keep getting a "readline() on unopened filehandle" on my for line:
Code:
my $ArcPathLookup = $argArcPath . $base . "*" . $ext;
warn "Lookup: $ArcPathLookup\n";
for my $curFile ( reverse <$ArcPathLookup> ) {
...
}
I get the following results:
Code:
/devuser/sjohnson # perl arcpathsave.pl edifile 5 "/devuser/sjohnson/save"
Lookup: /devuser/sjohnson/save/edifile*
readline() on unopened filehandle at arcpathsave.pl line 64.
Sorry it's probably something simple but I've looked arounds for a few hours and haven't found much, looked at the readline() and glob() but still not really understanding where and when you can add /path/filename.ext.
What we're trying to do is allow for archives to be placed in a different directory (optional arg)
We may also be using unix variables instead of a string on the command line.
Without the full code it's hard to figure out what's on line 64. The warning basically means you are trying to read a line (probably with <HANDLE>) where the HANDLE was not opened (or even defined) yet.
if I leave the path arg blank it works, but when the path is added I get the readline error.
While looking around I found this in a perl doc:
Code:
opendir(DIR, $dirname) or die "can't opendir $dirname: $!";
while (defined($file = readdir(DIR))) {
# do something with "$dirname/$file"
}
closedir(DIR);
If I am understanding this correctly:
it opens the dir
the while processes the files within the dir
then it closes it
I'm thinking that I can use this to rework the code to include an optional path arg. but I'll probably need to write 2 subs, one for the path arg and one for no path arg.
It's going to be messy but that's all I can think of right now...
