No matter how I program this:
this particular line: $data2[$a] =~ s/\n//;
will not remove the carraige return at the end. I've tried rewriting that line with these variations:
$data2[$a] =~ s/\n//;
$data2[$a] =~ s/[\n\r]//;
$data2[$a] =~ s/[\n\r]+//;
...and a couple other ways, but always the same result happens. I still get a variable value with some sort of carriage return added to the value. How do I remove the carraige return/new line from the value?
BTW "n" and "r" in the program commands should be "back slash + n" and "back slash + r".

What happened to my thread title?
Was suppose to be "Can't remove carriage returns w/PERL"
Also, it's a pain when yah can't post code properly with back slashes, etc.

That doesn't make the variable $data2[$a] contain a value without a carraige return. It didn't seem to do anything. Perhaps it was not used in the right place. What does that command do anyway?

Thanks perlworx.
While I ended up using another method, your method helped me find a very similar method:
chop(@data2);
Running it through that command 2 times removed all the new line characters. It seems that when I upload my flat file text database from my computer to my linux server, it interprets the single carraige return as a double carraige return. Weird. Anyways "chop" does the trick. Thanks for leading me to a successful method.

Good that you sorted the problem Curt. Sorry I am a little late in answering this topic.
'Chop' would strip the last character no matter what while chomp() will strip the newline alone. When you deal with binary files make sure that you set $/ explicitly to the appropriate value for your file format before using chomp().

chomp is the correct function to use - it removes ALL trailing newlines. chop removes only the last character, regardless of what it is.
E.g.,
#!/ust/local/bin/perl
$str = "aaannn";
chomp $str;
# now contains only "aaa"
chop $str
# now contains "aa"
