Re: How to pass directory variable using IPC::System::Simple

Why do you import IPC::System::Simple? Maybe that module can export a subroutine foldername?

I recommend that you construct and print the filename before trying to launch the external program. For example:

my $date = '2016-07-25';
my $filename = "$savedir/TEST-$date.jpg";

system(...);

To get at the current date, the easiest approach is to use the strftime function from the POSIX module:

my $date = strftime '%Y-%m-%d', localtime;
...

I honestly just used the Simple module just cuz someone told me to do so... literally. That's all I'm trying to do and I have no idea how to call the said command line without the module (screams help) Thanks for the POSIX module! I'll look that up for sure	[reply]

Hi bill5262, I made a mistake in my node, which I've now fixed, apologies! The line "`use IPC::System::Simple;`" should be "`use IPC::System::Simple 'system';`", because otherwise it has no effect, meaning that the default system function is called instead of IPC::System::Simple's version of `system` which has better error handling.
