[Boston.pm] taking in info from command-line command
OK, so I know there's an easy-ish way to handle this situation. But I'm currently running in circles, not finding the solution. Basically what I'm trying to do is run a system command (with either `command` or system(commnad) ) and retrieve the printed result form the command into a variable of some sort. So think of it this way: my $info = `ls`; or for Windows users: my $info = `dir`; If I run this from the command line it will print the results (because the command was run), but the output is NOT put into $info. I don't care what kind of variable (scalar, array, etc.) this information is stored in, but all the ways I've been trying are NOT working. I guess it's important to know that this will in the end be used in a web app. Thanks for any help. --Alex ___ Boston-pm mailing list Boston-pm@mail.pm.org http://mail.pm.org/mailman/listinfo/boston-pm

If it's dumping its output on STDERR, try adding 21 to the end of your command in back-ticks, that will redirect STDERR to STDOUT, and might get the output captured properly (though I haven't tried it).

Re: [Boston.pm] taking in info from command-line command
Thanks Tim, Though this was not the solution to my problem, I beleive that it helped me find that solution. I needed to specify the full path of the command I was trying. Since I was not specifying the full path I was getting an error message. After adding that code snippet I was informed of this :) Thanks for the help. --Alex Quoting Tim Wilde [EMAIL PROTECTED]: On Tue, 5 Jul 2005, Alex Brelsfoard wrote: OK, so I know there's an easy-ish way to handle this situation.
