I have quite a lot of servers where I need to ssh at workplace and I generally don’t remember all of them, so I wrote a simple yet useful script. In all the servers I have already copied my key so I dont need a password to login. Without much ado, here is the script.

echo ”Enter the server name:”
echo ”1. redhat”
echo ”2. fedora”

read server

if [ ”$server” = ”1” ]; then
ssh amit@redhat
else if [ ”$server” = ”2” ]; then
ssh amit@fedora
else
echo ”Not a valid choice”
fi
fi

If you want to mirror a <a class="zem_slink freebase/en/website" title="Website" rel="wikipedia" href="http://en.wikipedia.org/wiki/Website">website, the simplest tool I know if is <a class="zem_slink freebase/en/wget" title="Wget" rel="homepage" href="http://www.gnu.org/software/wget/">wget. Once you have used wget, you know the troubles associated with it. You also get added couple of files as search html files, which are useless and wastage of bandwidth for you as well as the <a class="zem_slink freebase/en/web_server" title="Web server" rel="wikipedia" href="http://en.wikipedia.org/wiki/Web_server">webserver.
