BATCH file to connect to Linux via SSH. How?

Question

First a screenshot that shows OpenSSH installed on Windows 10...

Above, I use the command ssh -V in the command prompt to make sure OpenSSH is installed.

Now.. It appears that throwing the following one liner into a .bat file to login to a linux server via ssh doesn't do anything.

ssh -p 22 [email protected]

When I type the same one liner into a windows 10 command prompt since Windows 10 now has OpenSSH built in, it logs me in just fine.

What I am missing?

Didn't work. With your approach the prompt thinks `ssh` is the hostname argument. — suchislife, Nov 08 '19 at 05:37
`C:\Windows\System32\OpenSSH\ssh.exe -p 22 [email protected]` — Gerhard, Nov 08 '19 at 05:41
That works. So... is my answer below still appropriate or I should update with your solution since we aren't really focusing on PowerShell? — suchislife, Nov 08 '19 at 05:45
You can leave you answer, I will post another one with my solution. — Gerhard, Nov 08 '19 at 05:45
Ok. You know... just before it authenticates successfully every time, there is this `key_load_public: invalid format`. This doesn't show when I use PuTTY. I wonder if it's a windows thing... — suchislife, Nov 08 '19 at 05:47
Yeah. Then I use private key to connect and it works every time. It just... shows `key_load_public: invalid format`. — suchislife, Nov 08 '19 at 05:50
Rather fix it properly. See the [link here](https://stackoverflow.com/questions/42863913/key-load-public-invalid-format) — Gerhard, Nov 08 '19 at 05:57

Firstly, do not name your batch file ssh.bat or ssh.cmd and it will probably be best if you use the full path to the executable:

@echo off
"C:\Windows\System32\OpenSSH\ssh.exe" -p 22 [email protected]
pause

but it is probably better to use the %windir% environment variable:

@echo off
"%windir%\System32\OpenSSH\ssh.exe" -p 22 [email protected]
pause
