Executing remote commands through SSH

Question

igor@IgorReinCloud ~/dbhandler $ ssh [email protected]:/dbhandler/dbhandler < git pull
bash: git: No such file or directory
igor@IgorReinCloud ~/dbhandler $ git pull

Does this mean I should create some kind of script with just git pull inside to be properly executed? Or I am doing something wrong?

[EDIT]

What I'm trying to achieve is following:

I'm on my Linux box trying to connect to one of my OSX laptops (192.168.1.3). This Mac laptop is running OSX 10.8. Up until recently everything was working fine, but then GitHub switched from using SSL 1.0 to SSL 1.2 or something like this. And of course trying to perform remote operations from OSX is now failing.

However if I try to perform this on Linux everything works as expected since Linux version of Git/OpenSSL is newer and therefore running git pull/fetch/push/etc will succeed.

And so my ultimate goal here is to do git pull to execute the git from the local machine (Linux) to update the repository that is located on remote machine (OSX).

I hope it is now clear what I'd like to achieve.

Answer 1

< is an operator to redirect a file as an input. git pull is a command, not a file. You can do it like this:

echo "git pull" | ssh [email protected]:/dbhandler/dbhandler

Or the correct way:

ssh [email protected]:/dbhandler/dbhandler git pull

Take a look at possible invocations in man ssh:

ssh (...) [user@]hostname [command]

You have an optional command there.

I wonder if your command doesn't need an additional fix:

ssh [email protected] bash -c "cd /dbhandler/dbhandler && git pull"

^ I don't think your path should be there when executing commands. With bash -c "some-commands" you can circumvent this.

Edit:

After clarification it seems that a good solution is mounting Mac's project folder on Linux machine and use git there, while doing everything else on Mac. You can do it by using SSHFS: https://www.digitalocean.com/community/tutorials/how-to-use-sshfs-to-mount-remote-file-systems-over-ssh

My preferred solution would be upgrading your Mac's git so it supports SSL 1.2. If there's no update for Mac yet, you can try compiling it yourself and installing the compiled version.
