linux man2html script

在linux中，可以利用系统提供的man2html命令，将linux命令的man手册转成html代码，将下面的源码保存为man2html.sh，这个脚本可以将man批量转化成html代码。

#!/bin/bash

if [ $# -eq 0 ]
then
    echo "Usage: ./man2html.sh /path/to/man/dirctory /path/to/html/output/dirctory"
    echo "Exampe: ./man2html.sh /usr/share/man/man1 /tmp/html1"
fi

dir=/usr/share/man/man1
output=/tmp/html1

if [ $# -eq 1 ]
then
    dir=$1
elif [ $# -eq 2 ]
then
    dir=$1
    output=$2
fi

echo "./man2html.sh ${dir} ${output}"

if [ ! -d $output ]
then
    mkdir -p $output
fi

if [ -d $dir ]
then
    mkdir -p /tmp/unzipped
    cd $dir
    for f in *.gz; do
        if [ -f $f ]
        then
            filename=$(basename "${f}" .gz)
            unzipfile="/tmp/unzipped/${filename}"
            outputfilename="${output}/${filename}.html"

            gunzip -c "${f}" > ${unzipfile}
            man2html ${unzipfile} > ${outputfilename}

            sed -i 's#^Content-type: text/html$##' ${outputfilename}
            sed -i 's#</HEAD>#<META charset="UTF-8"></HEAD>#' ${outputfilename}
        fi
    done
fi

echo "done!"
