Thanks for writing this script. It is really useful.

I found two small problems.

First, it is more convenient to create a new post using the following sample command:

./command create a new file

So here, we have 4 input parameters. However, you only manipulate the first argument.

so a better way is to use the following script:

# Post title
TITLE=""

for var in "$@"
do
    TITLE=$TITLE" $var"
done

# Trim leading spaces
TITLE="$(echo "${TITLE}" | sed -e 's/^[ \t]*//')"

Second, the final file has a leading "\n". It is better to remove it.

I put the new scripts on my blog.

Maybe something more compact, without colors and permalink tho:

#!/bin/bash
# Create a new jekyll post with the current date and the given title
# and print the path to the post file.
#
# author: andreasl

post_title="$*"
[ -z "$post_title" ] && printf 'Error: Script needs a post title.\n' && exit 1

repo_dir="$(git rev-parse --show-toplevel)"
post_date="$(date '+%Y-%m-%d')"
title_slug="$(printf -- "$post_title" | sed -E 's/[^a-zA-Z0-9]+/-/g' | tr "[:upper:]" "[:lower:]")"
post_path="${repo_dir}/_posts/${post_date}-${title_slug}.md"
[ -e "$post_path" ] && printf 'Error: Post exists already.\n' && exit 2

IFS= read -r -d '' front_matter << EOF
---
title: "${*}"
date: ${post_date}
tags: []
---
EOF

printf -- "${front_matter}" > "${post_path}"

printf -- '%s\n' "${post_path}"

This one above is a tiny masterpiece. :-)

Thanks man! This saved me a lot of time. :)

Zsh FWIW...

#!/bin/zsh

# Create and edit a new Jekyll post
# Based on bash script by @AamnahAkram
# https://gist.github.com/aamnah/f89fca7906f66f6f6a12 
#
# Usage: ./new-post.sh "title of your new post"

POSTS_DIR='src/_posts/'
TITLE=$1
# Lowercase all characters in TITLE
TITLE_LOWERCASE=${TITLE:l}
# Uppercase first character of each word in TITLE
TITLE_UPPERCASE=${(C)TITLE}
# Replace spaces in TITLE_LOWERCASE with underscores
TITLE_STRIPPED=${TITLE_LOWERCASE// /_}
DATE=`date +%Y-%m-%d`
TYPE='.md'
FILENAME=${DATE}-${TITLE_STRIPPED}${TYPE}
cd ${POSTS_DIR}
cat > ${FILENAME} <<EOF
---
layout: post
title: ${TITLE_UPPERCASE}
---


EOF
mvim ${FILENAME}

Thanks @langenhagen ! Excellent base.

I created a repo to let the script evolve in the future: https://github.com/brunetton/new_post.sh
