When I try to use an ssh command in a shell script, the command just sits there. Do you have an example of how to use ssh in a shell script?
SSH, also known as Secure Shell or Secure Socket Shell, is a network protocol that gives users, particularly system administrators, a secure way to access a computer over an unsecured network. SSH also refers to the suite of utilities that implement the SSH protocol.
Bash script SSH is a common tool for Linux users. It is needed when you want to run a command from a local server or a Linux workstation. SSH is also used to access local Bash scripts from a local or remote server.
Run the command "ssh username@host" to log in to the system. At the command prompt, run "top" to view process activity on the remote system. Exit top and be dropped to the remote command line. Type "Exit" to close the command.
You can start an SSH session in your command prompt by executing ssh user@machine and you will be prompted to enter your password. You can create a Windows Terminal profile that does this on startup by adding the commandline setting to a profile in your settings.
Depends on what you want to do, and how you use it. If you just want to execute a command remotely and safely on another machine, just use
ssh user@host command
for example
ssh user@host ls
In order to do this safely you need to either ask the user for the password during runtime, or set up keys on the remote host.
First, you need to make sure you've set up password-less (public key login). There are at least two flavors of ssh with slightly different configuration file formats. Check the ssh manpage on your system, consult you local sysadmin or head over to How do I setup Public-Key Authentication?.
To run ssh in batch mode (such as within a shell script), you need to pass a command you want to be run. The syntax is:
ssh host command
If you want to run more than one command at the same time, use quotes and semicolons:
ssh host "command1; command2"
The quotes are needed to protect the semicolons from the shell interpreter. If you left them out, only the first command would be run remotely and all the rest would be run on the local machine.
