fish

I'm running Fish on a Vagrant-controlled VM. I want to use ~vagrant as the place where VM-specific configuration gets dumped, so that's my $HOME . I have /vagrant as a directory shared with the host, and that's where I want to be all the time. When I log in to the VM, I'd like Fish to dump me into /vagrant/ . In Bash, I'd do this by putting cd /vagrant/ into ~/.bashrc . However, I see there's another question about changing directories in Fish and the comments suggest that putting cd /vagrant/ into ~/.config/fish/config.fish would be a mistake because Fish will implicitly evaluate it on every

I have stumbled on a problem with the fish shell (which is my favorite shell) when I am trying to use command substitution: gcc (pkg-config --libs --cflags gtk+-2.0 cairo) -o drawing_widget drawing_widget.c gcc: erreur: unrecognized command line option ‘-pthread -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/include/pango-1.0 -I/usr/include/atk-1.0 -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/libpng16 -I/usr/include/pango-1.0 -I/usr/include/cairo -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/pixman-1 -I/usr/include/freetype2 -I/usr/include/libpng16 -I/usr/include

Right now I'm forced to resort to using uname to get the operating system name and it works. But in bash there is the OSTYPE environment variable that is automatically set and I was wondering if there is something similar. From the fish user documentation it seems that the canonical way to execute code conditionally depending on the operating system type is using a switch statement with the uname results. See example: switch (uname) case Linux echo Hi Tux! case Darwin echo Hi Hexley! case FreeBSD NetBSD DragonFly echo Hi Beastie! case '*' echo Hi, stranger! end 来源： https://stackoverflow.com

How can I do something like set variable (some_command_that_may_return_a_string) if [ variable is set ] do_something and inversely how do I check if the variable is empty? set -q var (note the missing "$" - this uses the variable name ) can be used to check if a variable has been set. set -q var[1] can be used to check whether the first element of a variable has been assigned (i.e. whether it is non-empty as a list). test -n "$var" [fn0] (or [ -n "$var" ] ) can be used to check whether a variable expands to a non-empty string (and test -z is the inverse - true if it is empty). These will be

So I installed fish and oh-my-fish, and when i want to use rvm I get this error: ➜ avalancha git:(services) ✗ rvm use 2.1.0 Using /home/matias/.rvm/gems/ruby-2.1.0 fish: The '$' character begins a variable name. The character '{', which directly followed a '$', is not allowed as a part of a variable name, and variable names may not be zero characters long. To learn more about variable expansion in fish, type 'help expand-variable'. /home/matias/.config/fish/functions/rvm.fish (line 2): begin; set -xg rvm_bin_path "/home/matias/.rvm/bin" ; set -xg GEM_HOME "/home/matias/.rvm/gems/ruby-2.1.0" ;

I want the current command to be shown in the title of screen (or tmux). I tried following settings but it doesn't work. How can I make it work? .screenrc shelltitle "$ |fish" shell /usr/local/bin/fish .config/fish/config.fish set -x PS1 '\033k\033\\[\u@\h \W]\$ ' For fish version 2.1.0 you only have to edit ~/.config/fish/functions/fish_title.fish function fish_title hostname end For version 1.23.1 this doesn't seem to work. If the directories do not exist, first create them: mkdir -p ~/.config/fish/functions/ I think you're looking for fish_title . See documentation here . You could do
