在无意间发现了这么给力的一个shell脚本，脚本本身并不复杂，用到的技巧也不多，但不得不给这种思路点个赞！自己在Linux系统上测试了，效果不错，后期可能会根据需要修改一下前端的展示（其实也就是多设置几个HTML属性），但是就现在来说，已经非常实用了：
#! /bin/bash
helpDir=man_pages
main_file=./$helpDir/index.html
cmds=`
{
for j in ${PATH//:/ }
do
ls $j
done
} | sort | uniq `
rm -f -r $helpDir
mkdir $helpDir
echo "<head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> " >> $main_file
echo "<table border="1"><tr><th>命令</th><th>描述</th></tr>" >> $main_file
for i in $cmds
do
echo "processing "$i"..."
file=./$helpDir/${i}.html
echo "<head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> " >> $file
echo "<p><a href="index.html">返回目录</a></p>" >> $file
echo "<hr>" >> $file
echo "<pre>" >> $file
man $i >> $file 2>/dev/null &&
{
echo "</pre>" >> $file
describ=`sed -n -e '/NAME/ {n;p;q}' $file | cut -f 2 -d '-'`
echo "<tr>" >> $main_file
echo "<td><a href="$i.html">$i</a></td>" >> $main_file
echo "<td>$describ</td>" >> $main_file
echo "</tr>" >> $main_file
} ||
rm $file
done
echo "</table>" >> $main_file
