Hey all -
I'm having a problem with this slice of code... I keep getting a bareword found error where I open the file. I've tried running this on my linux machine, and I don't get any problems. Any ideas?
I get other bareword found errors whenever I open a file anywhere else in the script...
here's the exact error:
Bareword found where operator expected at dir.pl line 62, near "open(SLFILE,$file) || die("Cannot"
(Might be a runaway multi-line "" string starting on line 51)
I know it'll extend the length of this post, but here's the full code if you want to look at it.
I'm using activestate 5.6.31 on win98.
Sorry bout the length of the post... I know it's better to have too much information than too little though.
TIA

#Created by Leo Mendoza, 2001.
#Used to help expedite html file processing.
use strict;
my $lt = localtime;
my ($item,$datafile,$mydir,$lookFor);
if ($#ARGV < 1) {
print <<EOF
Created by Leo Mendoza, 2001.
Usage: perl dir.pl replace datafile [directory]
Options:
replace can be any meta tag name (eg:description, keywords, author, etc...)
datafile is a CSV file for the content of the tag.
If directory is not supplied, the current directory is used.
ex: perl "description" myKWFile "C:\\ATA\\website\\"
This will replace all the <meta name="description" content="xxx">
tags within the "C:\\ATA\\website" directory with
<meta name="description" content="data_from_myKWFile">
Currently parses only .htm or .html files.
EOF
