Full Discussion: capturing exceptions from an scp clause

You don't need to use $? when checking a command's return value. You can check the command directly.

Code:
if ! scp source destination
then
        echo "something bad happened" >&2
fi

Or even
Code:
scp source destination || echo "something bad happened" >&2

If anything goes wrong, it will likely print an error to standard error. If you redirect standard error into a logfile yourself before you run it, all error messages will go into it.

Code:
exec 2>path/to/logfile

touch / # Since you're not root, this should print 'permission denied' into logfile

app::nopaste::service::ssh

App::Nopaste::Service::ssh(3pm) 			User Contributed Perl Documentation			   App::Nopaste::Service::ssh(3pm)

NAME

       App::Nopaste::Service::ssh - copies files to your server using scp

AUTHOR

       Kevin Falcone "<falcone@cpan.org>"

       Thomas Sibley "<trs@bestpractical.com>"

ENVIRONMENT VARIABLES

       NOPASTE_SSH_SERVER
	   The hostname to which you ssh. The left-hand side of the colon in the scp.  For example: "sartak.org".

       NOPASTE_SSH_DOCROOT
	   The path on disk for your pastes. For example: "public_html/paste".

       NOPASTE_SSH_WEBPATH
	   The path for URLs. For example: "http://sartak.org/paste".

       NOPASTE_SSH_MODE
	   Octal permissions mode to set for the temporary file before uploading.  For example: 0644.

       NOPASTE_SSH_USE_DESCRIPTION
	   Use the supplied description in the paste filename for easier identification of pastes.  Defaults to the source filename, if any, but
	   is overridden by an explicit "-d" or "--description" command line argument.

APACHE CONFIGURATION RECOMMENDATIONS

       The following is a recommended Apache configuration you can drop into ".htaccess" in your paste dir.

	   RemoveHandler .cgi
	   RemoveHandler .pl
	   AddDefaultCharset utf-8
	   Options -ExecCGI -FollowSymLinks -Includes -MultiViews

       It prevents common means of script execution so that ".pl" and ".cgi" files won't run and defaults the character set to UTF-8 so browsers
       don't have to guess wrong.
