How can I tell ssh to look for config file in a location other than the default one: ~/.ssh/config?

-F configfile
Specifies an alternative per-user configuration file. If a configuration file is given on the command line, the system-wide configuration file (/etc/ssh/ssh_config) will be ignored. The default for the per-user configuration file is ~/.ssh/config.

This works but every time I need to enter the config file path. Is it possible to store this option as default somewhere?– motam79Commented Sep 12, 2018 at 2:34

@motam79 quoting: "[...] the system-wide configuration file (/etc/ssh/ssh_config) will be ignored.". Without system-wide file, you can't store this anywhere. (This is my own assumption without any hard evidence and testing!) Commented Sep 12, 2018 at 8:37

@motam79 If you're only starting ssh manually from the command line, you can make a shell alias. If you use other stuff (scripts, binaries, whatever) that look for ssh on the path, you could drop a wrapper script somewhere that has a higher priority than the real binary.– pt314Commented Sep 12, 2018 at 10:40
As of OpenSSH 7.3p1, you can Include other config files in ssh_config.
So, you could add to /etc/ssh/ssh_config:
Include ~/custom_ssh.conf
Don't think this will stop the default ~/.ssh/config from being loaded, however.
