Re^2: formatting output from system call

The output looks like this: USB::0x0699::0x0368::C010731::INSTR <- MEASU:IMMED:VALUE? USB::0x0699::0x0368::C010731::INSTR -> 9.9E37 I would want to pull the 9.9E37 out of that. The regex part should be easy, but I'm not quite sure how that would work with qx().

We suggested to use qx() to execute the command and capture the output, into a variable like below, instead of creating file. Ex: `use strict; use warnings; my $output = qx(date); print $output;` [download] After that you can use your regx on that variable and pull the output value. *All is well*	[reply] [d/l]

That is the more sensible way to do this, I will research the qx command and apply it to my script. Thankyou for your help.	[reply]
