Weekly Script #1 – ssh_key_scp.sh

Since I dont post on here to often I will try and post a weekly script that I find useful day-to-day.

First up is a short simple script to scp your private key to a defined server. Usage is pretty simple call the script with the username@hostname

e.g ./ssh_key_scp.sh username@hostname

If no ssh key already exists the script gives you the option to generate one.

if [ ! -f ~/.ssh/id_rsa.pub ];then
echo "Private key not found at $KEY"
while true; do
read -p "Do you wish to generate a private key?" yn
case $yn in
[Yy]* ) ssh-keygen -t rsa; break;;
[Nn]* ) exit;;
* ) echo "Please answer yes or no!";;


if [ -z $1 ];then
echo "Please specify user@host as the first parameter of this script"

echo "Putting your key on $1... "

ssh -q $1 "mkdir ~/.ssh 2>/dev/null; chmod 700 ~/.ssh; echo "$KEYCODE" >> ~/.ssh/authorized_keys; chmod 644 ~/.ssh/authorized_keys"

echo "done :D Key Uploaded!"


Thats it for this week, will post another next week.
