=head3 runcmd
|
|
Run the given cmd and return the output in an array (already chopped).
|
|
Alternately, if this function is used in a scalar context, the output
|
|
is joined into a single string with the newlines separating the lines.
|

Arguments:

command, exitcode, reference to output, streaming mode

Returns:

|
|
Error:

Normally, if there is an error running the cmd,it will display the
|
|
error and exit with the cmds exit code, unless exitcode
|
|
is given one of the following values:
|
|
0: display error msg, DO NOT exit on error, but set
|
|
$::RUNCMD_RC to the exit code.
|
|
-1: DO NOT display error msg and DO NOT exit on error, but set
|
|
$::RUNCMD_RC to the exit code.
|
|
-2: DO the default behavior (display error msg and exit with cmds
|
|
exit code.
|
|
number > 0: Display error msg and exit with the given code
|
|
|
|
Example:
|
|
my $outref = xCAT::BuildKitUtils->runcmd($cmd, -2, 1);
|
|
$::CALLBACK= your callback (required for streaming from plugins)
|
|
my $outref = xCAT::BuildKitUtils->runcmd($cmd,-2, 1, 1); streaming

reference to an array for efficiency.
