captumring output from STDERR
 

Hi Everybody,

Well I am writing a perl script and I execute a command. I would like to capture the error messages :

Let,

@ar = `ifconfig`;

One way is :

@ar = `ifconfig 2>&1`;
this directs error to console STDOUT and thus can be captured by the handle.

Can u seggest me another method to achieve the same.

If you want to catch error messages only:

ifconfig 2>>/path/to/some/file

The >> might be accessive, a single > should work.

Is there a reason you don't want to use the normal redirect (2>&1)?

This just appends STDERR to a file. rajatgarg would then have to open up said file and read from it--very expensive compared with 2>&1.
