Is there a way I can get the array size in fish shell?
The exact problem I have at hand is that I would like to do some operations on all array elements except the first one. So I was trying to find the size so that I can loop from 2 to $array_size.
If it is not possible, what is an alternative method?

To get the length of an array, we can use the {#array[@]} syntax in bash. The # in the above syntax calculates the array size, without hash # it just returns all elements in the array.
fish files in ~/. config/fish/conf. d/ . See Configuration Files for the details.
To create a custom prompt create a file ~/. config/fish/functions/fish_prompt. fish and fill it with your prompt. Is there a way to save multiple prompts, or add to the list of available prompts that are displayed when you run fish_config?
To be able to run fish scripts from your terminal, you have to do two things. Add the following shebang line to the top of your script file: #!/usr/bin/env fish . Mark the file as executable using the following command: chmod +x <YOUR_FISH_SCRIPT_FILENAME> .
count will print the number of elements. But if you want to just skip the first element, you can use slices:
> set arr one two three
> echo $arr
one two three
> echo $arr[2..-1]
two three
using the count command which is a command built into fish.
Example:
$ count $PATH
