    perhaps i too will post code on the internet

    here is a shell script i wrote for automating filenames for markdown files (blog posts):

    code 
    #!/bin/sh
set -e

datecmd="date +%Y-%m-%d"

if [ -z "$1" ]; then
  printf "Post title: " >&2
  read -r title
else
  title="$1"
fi

file="$($datecmd)_$title.md"

if [ -f "$file" ]; then
  printf "Error: post '$file' already exists.\n" >&2
  exit 1
fi

${EDITOR:-nano} "$file"

    im not sure why i made it since i could just look at what date it is and write it down manually in the file name, but i felt like doing that as a quick hack

    i thought most unix-like systems had it symlinked to a shell like dash. it’s what i have on my system (void linux), of course not as an interactive shell lol

    i use #!/bin/sh for posix scripts and #!/usr/bin/env bash for bash scripts. #!/bin/sh works for posix scripts since even if it’s symlinked to bash, bash still supports posix features.
