After coming across Modernizr’s compress bash script, I’ve been adding my own li’l bash scripts here and there in my projects. They help automate any repetitive task, or provide a shortcut for a bash command I don’t want to remember.

Development

Make a sweet bash script, like helloworld.sh:

#!/bin/bash
echo 'Hello world!'

Make the script executable by changing the permissions:

$ chmod 755 helloworld.sh

Run the script from the command line

$ ./helloworld.sh
# > Hello World

Examples

metafizzy.co / newpost.sh and dropshado.ws / newpost.sh: creates a new post from a template

#!/bin/bash

# creates a new post
# format as _posts/YYYY/YYYY-MM-DD-filename.ext
# usage:
#   $ ./newpost.sh my-new-post-filename

COPY_FILE=_posts/template.mdown
# create file
POST_FILE=_posts/$(date "+%Y/%Y-%m-%d")-$1.mdown

echo new post: $POST_FILE
cp $COPY_FILE $POST_FILE
# open it
mate $POST_FILE

demo / deploy.sh and desandro / deploy.sh: rsyncs project to remote server

#!/bin/bash
rsync -avz --exclude '.git' --exclude '*.sh' ./ $BERNA:~/www/demo

neo-vision / build.sh: moves release files into sub directory, compresses JS, zips it all up

#!/bin/bash

BUILD_DIR='neo-vision'
ZIP='neo-vision.zip'
REMOVABLES=("build.sh" "prettify.js" "lang-css.js" "README.mdown" $ZIP)

rm -rf $BUILD_DIR/
mkdir $BUILD_DIR
cp *.* $BUILD_DIR

# minifies prettify js
cat prettify.js lang-css.js | uglifyjs -nc > $BUILD_DIR/prettify.min.js

for REMOVE in "${REMOVABLES[@]}"
do
	rm $BUILD_DIR/$REMOVE
done

zip -r -u $ZIP $BUILD_DIR
