Hey guys, my first post on UNIX Forums(much overdue IMO)!
I've got this bit of code that doesn't seem to be working correctly for an Android app I'm working on:
Basically it types command.text(variable determined in Android app) into a screen session and hits ENTER. It works perfectly fine if its only one word, but if I want to do two words, I must manually put them in quotations in the actual app. Is there any way for me to wrap command.text in quotations programmatically?
Just out of curiosity I tried adding another
around command.text but it didn't change anything.
Any help would be greatly appreciated as I'm almost done the app and don't want to get stuck on a syntax issue.

There are are lots of examples of piping output FROM the 'ls' command TO another command, but how does one pipe output TO the 'ls -l' command?
For example, use 'which' to find a file, then use 'ls -l' to view the permissions, groups, etc. in a single step:
which <filename> | ls -l
returns... (4 Replies)

plack::middleware::lint
Plack::Middleware::Lint(3pm) User Contributed Perl Documentation Plack::Middleware::Lint(3pm)NAME
Plack::Middleware::Lint - Validate request and response
SYNOPSIS
use Plack::Middleware::Lint;
my $app = sub { ... }; # your app or middleware
$app = Plack::Middleware::Lint->wrap($app);
# Or from plackup
plackup -e 'enable "Lint"' myapp.psgi
DESCRIPTION
Plack::Middleware::Lint is a middleware component to validate request and response environment formats. You are strongly suggested to use
this middleware when you develop a new framework adapter or a new PSGI web server that implements the PSGI interface.
This middleware is enabled by default when you run plackup or other launcher tools with the default environment development value.
DEBUGGING
Because of how this middleware works, it may not be easy to debug Lint errors when you encounter one, unless you're writing a PSGI web
server or a framework.
For example, when you're an application developer (user of some framework) and see errors like:
Body should be an array ref or filehandle at lib/Plack/Middleware/Lint.pm line XXXX
there's no clue about which line of your application produces that error.
We're aware of the issue, and have a plan to spit out more helpful errors to diagnose the issue. But until then, currently there are some
workarounds to make this easier. For now, the easiest one would be to enable Plack::Middleware::REPL outside of the Lint middleware, like:
plackup -e 'enable "REPL"; enable "Lint"' app.psgi
so that the Lint errors are caught by the REPL shell, where you can inspect all the variables in the response.
