Tipps & Tricks
SSH
To pass the password to the ssh password promt you need another tool, too: sshpass .
Obvious way
$ pass -c Customers/CustomerA/myuser@sshhost
$ ssh myuser@sshhost
Password:<paste the copied password>
myuser@sshhost:~$
Cooler way
Create the password entry
Put only the password at the first line (needed for sshpass).
$ pass edit Customers/CustomerA/myuser@sshhost
Create an alias
$ alias customer-sshhost='sshpass -f <(pass Customers/CustomerA/myuser@sshhost) ssh myuser@sshhost'
Use it
$ customer-sshhost
myuser@sshhost:~$
