dotpath

Set your shell's PATH from a file, preserving uniqueness.

Why? So you can easily configure your shell's PATH and remove duplicate entries, quickly & without fuss.

This Go version adds ~2.57ms to my shell startup time, compared to the 14-22ms I was getting using basic bash functionality.

Usage

# Build and run
make
eval"$(./dotpath)"# Test that it workedecho$PATH| tr ':''\n'| sort

$ ./dotpath -h
Usage of ./dotpath:
-allowInvalid
Add invalid directories to PATH
-allowMissing
Add non-existent directories to PATH (default true)
-file string
The location of your paths file (default "~/.paths")
-path string
PATH to add onto (default "$PATH")

Bash / ZSH / Fish / etc

Add eval "$(./dotpath)" to your ~/.bashrc / whatever your shell's config is called.

# Optional: Add dotpath to your path
mkdir -p ~/.local/bin
cp dotpath ~/.local/bin/

Configuration

Create a file called ~/.paths (or any other name, this is just the default).

Each path has it's own line:

$HOME/.local/bin
$HOME/.local/bin/gradle/bin
$HOME/.cargo/bin
$HOME/.android/sdk/tools/bin
$HOME/.android/sdk/cmdline-tools/latest/bin
$GOPATH/bin
