It appears that the Fish shell does not have that kind of for loop, but instead requires you to take a different approach. (The philosophy is apparently to rely on as few syntactic structures and operators as possible, and do as much with commands as possible.) Here’s how I did it, although I assume there … Read more
You are probably seeing the result of LSCOLORS, which you can look up in the ls man page or Google. The reason that you see this with fish and not, say, bash, is that fish wraps ls in a function that passes the -G flag, as you can see: > functions ls function ls –description … Read more
@glenn already got the answer, but I’ve found a simpler way of showing the git prompt on fish. From the terminal, in fish, type fish_config. This will open a browser window. Select the second tab prompt and under there select Classic + Git`. This will show the commands required to show Git on the terminal … Read more
In fish, your arguments are contained in the $argv list. Use list slicing to access a range of elements, e.g. $argv[2..-1] returns all arguments from the second to the last. For example function loop –description “loop <count> <command>” for i in (seq 1 $argv[1]) eval $argv[2..-1] end end Usage $ loop 3 echo hello world … Read more
That syntax works in fish too. A demo: $ function cmd1 echo “this is stdout” echo “this is stderr” >&2 end $ function cmd2 rev end $ cmd1 | cmd2 this is stderr tuodts si siht $ cmd1 &| cmd2 rredts si siht tuodts si siht Docs: https://fishshell.com/docs/current/language.html#redirects
if [ “abc” != “def” ] echo “not equal” end not equal if [ “abc” = “def” ] echo “equal” end if [ “abc” = “abc” ] echo “equal” end equal or one liner: if [ “abc” = “abc” ]; echo “equal”; end equal
According to the official Fish documentation, you can use the $status variable: How do I get the exit status of a command? Use the $status variable. This replaces the $? variable used in some other shells.
Fish uses options on the set command to manipulate shell variables. Unset a variable with the -e or –erase option. set -e myvar Additionally you can define a function function unset set –erase $argv end funcsave unset or an abbreviation abbr –add unset ‘set –erase’ or an alias in ~/.config/fish/config.fish alias unset ‘set –erase’
Found that the greeting message is set in fishd.Machine.local. To override the following to ~/.config/fish/config.fish: set fish_greeting
