### Shell Script Example

Source: https://github.com/sveetch/djangocodemirror/blob/master/djangocodemirror/static/CodeMirror/mode/shell/index.html

This snippet demonstrates a typical shell script for cloning a repository, generating HTTPS credentials, and starting a server. It includes commands for key generation, certificate signing, and server startup, followed by a process to stop the server.

```shell
#!/bin/bash
# clone the repository
git clone http://github.com/garden/tree
# generate HTTPS credentials
cd tree
openssl genrsa -aes256 -out https.key 1024
openssl req -new -nodes -key https.key -out https.csr
openssl x509 -req -days 365 -in https.csr -signkey https.key -out https.crt
cp https.key{,.orig}
openssl rsa -in https.key.orig -out https.key
# start the server in HTTPS mode
cd web
sudo node ../server.js 443 'yes' >> ../node.log &
# here is how to stop the server
for pid in `ps aux | grep 'node ../server.js' | awk '{print $2}'` ;
do
  sudo kill -9 $pid 2> /dev/null
done
exit 0
```

```livescript
# meta
export installPrelude = !(target) ->
  unless target.prelude?isInstalled
    target <<< out$
    # using out$ generated by livescript
    target <<< target.prelude.isInstalled = true
export prelude = out$
