./maketag 是bash 脚本， 具体内容为 :
#!/bin/bash
# This also work when used the command as follow :
    # [ROOT=/ROOT] slackpkg install-template INSTALL.TEMPLATE
TAGNAME="${TAGNAME:-tagfile}"
TEMPLATE="${TEMPLATE:-/dev/stdin}"
VERSION='1.0.0'
ApName="$(basename $0)"
USAGE="$ApName [-f TEMPLATE_FILE] DIR1 DIR2 ...
--version, -V    Output the ${ApName}'s version
--help, -H    Output the ${ApName}'s help"
if echo "$*" | grep -qwEe '(--version|-V)' ; then
    echo "$VERSION"
    exit 0
elif echo "$*" | grep -qwEe '(--help|-H)' ; then
    echo "$USAGE"
    exit 0
fi
while [ -n "$1" ]
do
    case "$1" in
        -f)
        if [ ! -r "$2" ] ; then
            echo "$2 is not readable" >&2
            exit 1
        fi
        TEMPLATE="$2"
        shift 2
        ;;
        *)
        if [ ! -d "$1" -o ! -x "$1" ] ; then
            echo "\"$1\" is not directory or do not have 'x' permission" >&2
            shift
            continue
        fi
        find "$1" -type f -name "$TAGNAME" -print0 | xargs --null sed -i -e 's/:.*$/:SKP/'
                echo '/^.*:.*$/ {' >"/tmp/${ApName}.$$"
        sort -u "$TEMPLATE" | sed -e 's#^.*$#s/^&:.*$/&:ADD/; t;#' >>"/tmp/${ApName}.$$"
