Shell Programming and Scripting

Code:

ssh-add -t 30 >/dev/null 2>&1
LOGNAME=`whoami`
cp $HOME/.ssh/known_hosts $HOME/.ssh/known_hosts.org grep -v localhost 
$HOME/.ssh/known_hosts.org > $HOME/.ssh/known_hosts

ssh -1 -f -l $LOGNAME -o "ForwardX11 yes" -o "StrictHostKeyChecking no"
-L 6003:1.1.1.1:2222 ext-proxy-2 sleep 5 >/dev/null 2>&1 xterm 
-title GIBFDX -e ssh -1 -q -o "StrictHostKeyChecking no" -l steve -p 
6003 -L 8080:server.address.com:8080 localhost &

can anyone decipher the above script word for word if possible I know what certain bits do but it would be great if an expert could explain, sorry im new to scripting and will also check the newbie threads.

thanks in advance

First block refers to adding a ssh key, setting the logname variable and copying the know_host file while removing the localhost info.

man ssh-add will give you the infos you need.

Second block connects to a some remote host using options opening up a xterm and connecting to another host ... not sure why he needed the xterm there thought...

man ssh will give you the infos you need.

TIP: you should NEVER EVER put real ip's/ports/login info in a post... You are asking for real trouble.
