19 Sys::VirtConvert::ExecHelper is a substitute for system() when you
20 don't want any command output. Sys::VirtConvert::ExecHelper does,
21 however, make STDOUT and STDERR available in a combined stream if it is
22 required, for example because the executed command failed.
23
25 run(@command)
26 Run @command, which is an array containing the command and its
27 arguments.
28
29 The command will be executed immediately. ExecHelper will block
30 until the command exits.
31
32 status
33 Return the exit status of the executed command.
34
35 output
36 Return the combined stdout and stderr of the command.
37
38 WARNING: This command puts the output in a string in memory. Don't
39 use this if the output could be large.
