Bash function to edit scripts faster

edit ✏️

I am often editing my own scripts as I develop them. I want to make a better workflow for working with scripts like this.


Currently I am combining nvim with a which subshell to etit these files like this.

for now lets use my todo command as an example

nvim `which todo`

First pass

On first pass I made a bash function to do exactly what I have been doing.

ewhich () {$EDITOR `which "$1"`}

The $1 will pass the first input to the which subshell. Now we can edit our todo script like this.

ewich todo

Note, I use bash functions instead of aliases for things that require input.

Final State

This works fine for commands that are files, but not aliases or shell functions. Next I jumped to looking at the output of command -V $1 .

ewhich () {
case `command -V $1` in
    "$1 not found")
        FILE=`fzf --prompt "$1 not found searching ..." --query $1`
        [ -z "$FILE" ] && echo "closing" || $EDITOR $FILE;;
    *"is a shell builtin"*)
        echo "$1 is a builtin";;
    *"is an alias"*)
        $EDITOR ~/.alias +/alias\ $1;;
    *"is a shell function"*)
        $EDITOR ~/.alias +/^$1;;
        $EDITOR `which "$1"`;;

a bit more ergo, and less readable

To make it easier to type, at the sacrifice of readability for anyone watching I added a single character e alias to ewhich. So when I want to edit anything I just use e .

alias e=ewhich


Here is a quick screencast of how it works.
