Net::FTP and variables

[perlnovice]

I know this must be a very simple question, but how do you pass a variable?

For example, this doesn't work when I try it:
$variable = somefile;


$ftp->get("$variable"


Any help would be much appreciated.

when assigning to a variable, you shouldn't use barewords, so try:[tt]
$variable = "somefile";
$ftp->get("$variable"[/tt] "If you think you're too small to make a difference, try spending a night in a closed tent with a mosquito."

If I wanted to make the variable a regular expression, would that still be enclosed in double quotes?

"...make the variable a regular expression..."
um, if you want to use a variable in a regular expression, you can do the following:[tt]
$var = "someword";
if ($string =~ m~$var~) {do stuff}[/tt]

in general, barewords should only be subroutine calls. if you want to assign a string to a variable, put some sort of quotes around it(well, not backtiks). "If you think you're too small to make a difference, try spending a night in a closed tent with a mosquito."

Have you tried

$ftp->get($variable);

without the quote?

Sorry about the my unspecific question. Actually, what I wanted to know was how to use the FTP module to get a file that matches a certain pattern. I wanted to know whether you can pass a pattern as a variable. I only know how to get a specific file name via

$ftp->get($variable)

but is it possible to make that variable a regular expression so that it ftp's anything that matches a pattern I choose?

 

[stillflame]

you could much easier call $ftp->ls() and regex the return from that to make sure you get files that actually exist. try something like:[tt]
my @ls = $ftp->ls();
foreach (@ls)
{
if (m~pattern~)
{
$ftp->get($_);
}
}[/tt] "If you think you're too small to make a difference, try spending a night in a closed tent with a mosquito."

There is also a kind of quote operator specifically for regular expression. Read up on the qr() operand in the perlop manpage.
