# shell-scripts

A collection of hopefully useful shell scripts

## Coding style

* Use tabs for indentation

* Prefix functions with _

* Variable names are UPPERCASE

Example:

```sh

while getopts ":b:ht" OPT; do

	case $OPT in

		b)

			BODY="$OPTARG"

			;;

		h)

			_usage

			;;

		t)

			SUBJECT="Test mail "

			BODY="Sent on $(date) to $MAILLOG_EMAIL."

			echo "Sending test mail to $MAILLOG_EMAIL."

			;;

		\?)

			echo "Invalid option: -$OPTARG" >&2

			;;

	esac

done

shift $((OPTIND-1))

if [ -z "$SUBJECT" ]; then

	SUBJECT="$1"

fi

FILE="$2"

if [ -z "$SUBJECT" ]; then

	_usage

fi

TMP_FILE=/tmp/maillog.sh_$(date +%s)

if [ ! -f "$FILE" ] && [ -n "$BODY" ]; then

	echo "$BODY" > $TMP_FILE

	FILE=$TMP_FILE

fi

if [ ! -f "$FILE" ]; then

	FILE=$TMP_FILE

	while read DATA; do

		echo "$DATA" >> "$FILE"

		echo "$DATA"

	done

fi

mail -s "$SUBJECT" $MAILLOG_EMAIL < "$FILE"

```

## Standard option `-h` or `--help`

```sh

_usage() {

	echo "Usage: $(basename "$0")

Options:

	-h, --help: Show this help message."

}

```

```sh

if [ "$1" = '-h' ] || [ "$1" = '--help' ] ; then

	_usage

	exit 0

fi

```

# Test

Run test with this command: `make test`
