Having gotten tired of manually installing my ssh pubkey on boxes I
wondered if
there might be a way to automate the process. This handy little shell script
ssh-wrapper was the result. I save it as ~/bin/pubkey-installer.sh and
alias my
ssh command to this and always get my public key automatically installed
on the
box I log into. I have tried to make is as generic and work just like the
normal ssh as possible. Improvements are welcome.
alias ssh='~/bin/pubkey-installer.sh'
#!/bin/sh -x
