Bash dtb create.sh script

Updated the script to create a markdown dtb file to the following:

FILE=_posts/$(date +%Y-%m-%d)-day$(date +%j).markdown
DATE=$(date +%Y-%m-%d\ %H:%M:%S\ +0100)

if test -f "$FILE"; then
        vim $FILE
        exit 1
fi

echo "Creating file $FILE"
touch $FILE
echo "Adding stuff"

/bin/cat <<EOM >> $FILE
---
layout: post
title:  "Day $(date +%j)"
date:   $DATE
categories: []
---

EOM

vim $FILE

Now it’s closer to create_or_open.sh and doesn’t overwrite anything if run again by error, doesn’t add any unused parts, and opens the file if it exists already.

Bash check if file exists

if test -f "$FILE"; then
        vim $FILE
        exit 1
fi

Bash exit script

exit 1 or whatever status code.

Bash suppress output of command (bash redirection)

SO:

command > /dev/null 2>&1 redirects both stdout and stderr to /dev/null;

command &> /dev/null & works for me too, though it may not work in all shells. command > /dev/null still shows errors.
