# NAME Shell::Carapace - cpanm style logging for shell commands # SYNOPSIS use Shell::Carapace; my $shell = Shell::Carapace->new( verbose => 1, # tee shell cmd output to STDOUT/STDERR logfile => '/path/to/file.log', # output is always written to this file ); my $output = $shell->local(@cmd); my $output = $shell->remote($user, $host, @cmd); # Useful for testing: # The noop attr tells local() to not run the shell cmd # Instead local() will return the cmd as a quote sring $shell->noop(1); my $cmd = $shell->local(@cmd); # DESCRIPTION cpanm does a great job of not printing unnecessary output to the screen. But sometimes you need verbose output in order to debug problems. To solve this problem cpanm logs at a verbose level to a logfile. This module provides infrastructure so developers can easily add similar functionality to their command line applications. Shell::Carapace is mostly a very small wrapper around Capture::Tiny. # ERROR HANDLING local() and remote() both die if a command fails by returning a positive exit code. # SEE ALSO - Capture::Tiny::Extended - Net::OpenSSH Net::OpenSSH has better performance because it uses a single ssh connection for the life of the object. Its a mature project with lots of functionality. - Capture::Tiny - IPC::System::Simple # About the name Carapace: n.
