SSH: sshpass

 

 

 

1. -f filename Take password to use from file
   

   sshpass -f password ssh intrinsic pmap --version

    

2. -d number Use number as file descriptor for getting password
   

   exec {fd}< password
   sshpass -u$fd ssh intrinsic pmap --version
   eval "exec $fd<&-"

    

3. -p password
   

   sshpass -p password ssh intrinsic pmap --version

    

4. -e 
   

   SSHPASS=intrinsic sshpass -e ssh intrinsic ethtool ens160

    

5. -P  Set the password prompt. Sshpass searched for this prompt in the program's output to the TTY as an indication when to send the password. By default sshpass looks for the string

   "assword:" (which matches both "Password:" and "password:"). If your client's prompt does not fall under either of these, you can override the default with this option
