Install Sshpass on OSX

, ,

Ever needed to run ssh commands from a non-interactive shell, and not being able to use keys? Well sshpass is what you need!

I use it for running ssh commands from Automator scripts on OSX. It is quite similar in function to Putty’s Pageant handling of keys.

Pre-reqs:

Please not that Xcode is required to compile as we download the source, which works on most *nix systems.

Download the source files

curl -O -L http://downloads.sourceforge.net/project/sshpass/sshpass/1.06/sshpass-1.06.tar.gz && tar xvzf sshpass-1.06.tar.gz

Prepare for make

cd sshpass-1.06
./configure

make and install

sudo make install

Command parameters

Usage: sshpass [-f|-d|-p|-e] [-hV] command parameters
   -f filename   Take password to use from file
   -d number     Use number as file descriptor for getting password
   -p password   Provide password as argument (security unwise)
   -e            Password is passed as env-var "SSHPASS"
   With no parameters - password will be taken from stdin

   -P prompt     Which string should sshpass search for to detect a password prompt
   -v            Be verbose about what you're doing
   -h            Show help (this screen)
   -V            Print version information
