Proc::ChildError - Explain process child error
This document describes version 0.04 of Proc::ChildError (from Perl distribution Proc-ChildError), released on 2016-01-06.
Produce a string description of an error number. $child_error defaults to $? if not specified. $os_error defaults to $! if not specified.
$child_error
$?
$os_error
$!
The algorithm is taken from perldoc -f system. Some sample output:
failed to execute: No such file or directory (-1) died with signal 15, with coredump exited with value 3
An options hashref can be specified as the first argument to add information. Currently known keys:
prog => str
Program name/path, to include in error messages:
/usr/bin/foo failed to execute: Permission denied (-1) foo died with signal 15, with coredump /usr/bin/foo exited with value 3
Process::Status provides a lightweight OO interface for $?. I recommend this module now over Proc::ChildError.
IPC::System::Simple provides a replacement for Perl's system(), with the difference that it will print a diagnostic error message similar to what Proc::ChildError provides. You only need to do use IPC::System::Simple qw(system) and use system() as usual. Recommended.
system()
Proc::ChildError
use IPC::System::Simple qw(system)
