NAME

    $NAME_ $VERSION_ - $PURPOSE_

SYNOPSIS

    $SYNOPSIS_

DESCRIPTION

    $NAME_ converts ascii files with html content to plain text. It replaces the
    previous suffix, if any, with a \"txt\" suffix. It skips the following files:

    - binary files
    - directories
    - files that already have the same name as <input_file>.txt

    Option -r, removes the input file after conversion.

EXAMPLES

    Use find with xargs to run the script recursively on multiple files. For
    example, to convert all html files to text recursively:

    find . -name \"*.html\" | xargs $NAME_

"; exit 1; }

# arg check
[ $# -eq 0 ] && { echo >&2 missing argument, type $NAME_ -h for help; exit 1; }

# var initializing
rm_html=
verbose=

# option and argument handling
while getopts vhmlr options; do

    case $options in
        r) rm_html=on ;;
        v) verbose=on ;;
        h) usage ;;
        m) manual | more; exit 1 ;;
        l) more $0 ;;
       \?) echo invalid or missing argument, type $NAME_ -h for help; exit 1 ;;
    esac

# check if required command is in $PATH variable

[[ $? != 0 ]] && { echo >&2 the required \"lynx\" command is not in your PATH variable; exit 1; }

# main
for a in "$@"; do

    file $a | grep -q text # testing if input file is an ascii file
    [ $? == 0 ] && is_text=0 || is_text=1

    if [ -f $a ] && [[ ${a#*.} != txt ]] && (( $is_text == 0 )); then

        if [ -f ${a%.*}.txt ]; then
            echo ${NAME_}: skipping: ${a%.*}.txt file already exist
            continue
        else
            [[ $verbose ]] && echo "${NAME_}: converting: $a -> ${a%.*}.txt"
            lynx -dump $a > ${a%.*}.txt
            [[ $? == 0 ]] && stat=0 || stat=1
            [[ $stat == 0 ]] && [[ $verbose ]] && [[ $rm_html ]] && echo ${NAME_}: removing: $a
