Q:

Specify different options for scp and ssh in .ssh_config file

I am using ~/.ssh/config file to set my ssh options. 
I want to specify different settings for scp and ssh to the same host.  Is it possible to do it? 
I went through the documentation, but couldn't a way to do it. 

A:

I'd make a second config file, ~/.ssh/scp_config, and then use a shell alias for scp with the -F option to specify the config file:
alias scp="scp -F ~/.ssh/scp_config`

(This is an untested zsh alias; I don't know how different Bash alias' are, but the idea should be similar.  Note also that this may still require you to use scp -F <file> in scripts).
