Question

I have a Z-shell configuration that I use on multiple servers and my personal computer. On my personal computer I have an alias to an executable we will call foo. Here is the line in my zshrc to alias to this program:

alias foo=/path/to/foo

On several servers the path to foo is different and I can not move it to a common directory like ~/bin:

alias foo=/sever/path/to/foo

I need the alias to be foo on all machines, so I cannot create two seperate alias like foo and foo-server for example. Is there a way to have the Z-shell detect what machine I am on and change the alias to foo automatically? Naively, something like:

if on personal computer:
alias foo=/path/to/foo
else:
alias foo=/sever/path/to/foo

Answer 1

For anyone else that comes across this, the best solution I could find is:

#{{{ Alias foo if it is in a specific location
if [[ -x ="/path/to/foo" ]]; then
    alias foo='/path/to/foo'
fi

#}}}

Thanks to larsmans for suggesting the -x flag
