Hi all,
I’ve been a zsh shell user for a while and after I’ve discovered fish shell, I
became interested in it and decided to slowly migrate to it. I currently have a
couple of expressions and settings in .zshenv and .zshrc that I’d like to port
to the fish configuration.
My question is the following:
Does fish have a mechanism to tell if a directory exists? This could be extra
useful to set environment variables based on that condition. The POSIX
equivalent looks like this:
if [[ -d "${HOME}/.bin" ]]; then
export PATH=~/bin:${PATH}
fi
I’d like to see how to use the same (and similar) functions in fish shell, such
as...
* Testing if a directory exists (-d)
* Testing if a file exists (-a)
* Testing if a file is executable (-x)
Thanks in advance,
— Attila
