Using Net::SSH::Perl To Find A Pattern in a remote file and print info on matched file

Here's How You Can Do That:
Code:
#! /usr/bin/perl

use strict;
use warnings;
use Net::SSH::Perl;

my $user = '';
my $pass = '';
my $host = '';
my $port = 22;
my $DEBUG = 0;
my $attr = { debug => $DEBUG, port => $port, protocol => '2,1'};

my $cmd = qq~perl -lne 'if ( /(PAT_HERE)/ ) { printf "PATTERN: %s LINE: %d FILE: %s INODE %s", \$1, \$., \$ARGV, (stat \$ARGV)[1]; }' *~;
my $ssh = Net::SSH::Perl->new($host, %$attr);
$ssh->login($user, $pass);
my ($stdout, $stderr, $exit) = $ssh->cmd($cmd);
print $stdout, "\n";

The above code expects you to replace the string "PAT_HERE" with the one you are looking for.

The code searches the files in the user-you-logged-in-as' ( $user ) home directory. If you want to search in other directories change the "cmd" line to something like this, where the the string " \/some\/dir\/* " is a directory you want to search:

Code:
my $cmd = qq~perl -lne 'if ( /(PAT_HERE)/ ) { printf "PATTERN: %s LINE: %d FILE: %s INODE %s", \$1, \$., \$ARGV, (stat \$ARGV)[1]; }' \/some\/dir\/*~;

More effort will be required if you want to handle situations in which no matches are returned gracefully.

Hope That Helps.

ssh-keysign

SSH-KEYSIGN(8)						    BSD System Manager's Manual 					    SSH-KEYSIGN(8)

NAME

     ssh-keysign -- ssh helper program for host-based authentication

SYNOPSIS

     ssh-keysign

DESCRIPTION

     ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during host-based authentication.

     ssh-keysign is disabled by default and can only be enabled in the global client configuration file /etc/ssh/ssh_config by setting
     EnableSSHKeysign to ``yes''.

     ssh-keysign is not intended to be invoked by the user, but from ssh(1).  See ssh(1) and sshd(8) for more information about host-based authen-
     tication.

FILES

     /etc/ssh/ssh_config
	     Controls whether ssh-keysign is enabled.

     /etc/ssh/ssh_host_dsa_key
     /etc/ssh/ssh_host_ecdsa_key
     /etc/ssh/ssh_host_ed25519_key
     /etc/ssh/ssh_host_rsa_key
	     These files contain the private parts of the host keys used to generate the digital signature.  They should be owned by root, read-
	     able only by root, and not accessible to others.  Since they are readable only by root, ssh-keysign must be set-uid root if host-
	     based authentication is used.

     /etc/ssh/ssh_host_dsa_key-cert.pub
     /etc/ssh/ssh_host_ecdsa_key-cert.pub
     /etc/ssh/ssh_host_ed25519_key-cert.pub
     /etc/ssh/ssh_host_rsa_key-cert.pub
	     If these files exist they are assumed to contain public certificate information corresponding with the private keys above.

SEE ALSO

     ssh(1), ssh-keygen(1), ssh_config(5), sshd(8)

HISTORY

     ssh-keysign first appeared in OpenBSD 3.2.
