A shell script I wrote because I got tired of typing the same dozen commands to start a new note or project. No install step, no config file, no dependencies — drop it on your PATH and it works. I use it every day.
What it does
Two things, done well: create files and directories in a single command, and insert multi-line blocks of text into a file without heredoc syntax. The second one took the most work to get right.
# Create a nested file with content
puravida folder/file.txt "hello"
# Multi-line insertion — paste content, end with ~
puravida folder/file.txt ~
first line
second line
~Why Bash
Most machines have Bash. You don't need Node, Python, or a package manager installed to run it. That portability matters when you're setting up a new environment or dropping into someone else's machine. The constraint also kept the scope honest — if it couldn't be done cleanly in pure Bash, it probably shouldn't be in the tool.
