Scrutinizer - sysadmins do put two or three commands together on the fly. I do. Pipe this command into this other command and then sort the output. That is essentially what the -exec predicate does for the find command.

Scripts coded as giant one-liners are out of bounds. Period. rbatte1 covers why really well.

I thought we were discussing the massive one-liners we see here a lot. We seem to want to define good and bad one-liners here. So let's say one-liners in scripts meant to be part of production should not be written as "multi-blobs" of piped commands.

Where can I rant?

First of all, apologies to the admins for not reading the rules totally and missing the bit about ranting off about other OSs. But that raises a question. Where do you go to have a good rant, to vent your disgust at various corporations and thier hideous behaviour? :confused:

A rant...

Hi guys... (Apologies for any typos etc...) This is basically a rant. I have been doing kids level projects and writing code to suit since around 1982, for the uProfessor, for the Sinclair Spectrum and later for the QL, IBM-XT in MS-DOS and after that for a 386DX40 up to Windows 95, until I...

ouse

ouse(3pm)						User Contributed Perl Documentation						 ouse(3pm)

NAME

       ouse - syntactic sugar to make Mouse one-liners easier

SYNOPSIS

	 # create a Mouse class on the fly ...
	 perl -Mouse=Foo -e 'has bar => ( is=>q[ro], default => q[baz] ); print Foo->new->bar' # prints baz

	 # loads an existing class (Mouse or non-Mouse)
	 # and re-"opens" the package definition to make
	 # debugging/introspection easier
	 perl -Mouse=+My::Class -e 'print join ", " => __PACKAGE__->meta->get_method_list'

DESCRIPTION

       ouse.pm is a simple source filter that adds "package $name; use Mouse;" to the beginning of your script and was entirely created because
       typing perl "-e'package Foo; use Mouse; ...'" was annoying me... especially after getting used to having "-Moose" for Moose.

INTERFACE

       "ouse" provides exactly one method and it is automatically called by perl:

       "oose->import()">
	   Pass a package name to import to be used by the source filter.

DEPENDENCIES

       You will need Filter::Simple and eventually Mouse

INCOMPATIBILITIES

       None reported. But it is a source filter and might have issues there.

SEE ALSO

       oose for "perl -Moose -e '...'"

       For all intents and purposes, blame:

       Chris Prather  "<perigrin@cpan.org>"

       ...who wrote oose.pm, which was adapted for use by Mouse by:

       Ricardo SIGNES "<rjbs@cpan.org>"
