Convert text to html codes

I was surprised there was no simple script out here to do this conversion. I took the an table of html ascii and wrote this bash script.

I know there are functions to convert text to ascii. I didn't want to go through the hassle of formatting it for HTML.

This script accepts as input the text you want to convert and also a html formatted table of ascii codes.

#!/bin/sh
# $1 input text
# $2 ascii table



to_process=$1
res=""
for ((i=0;i<${#to_process};i++))
{
 letter=${to_process:i:1}

 if [[ $letter == "." ]]
 then
  res="${res} &#46;"
 else
  line_no=`grep -n "<td>$letter</td>" $2 | cut -f 1 -d ':'`
  ((line_no++))

  if [[ ${#line_no} -gt 0 ]]
  then

   part=`sed -n "${line_no}p" $2 | sed -e 's/<td>//' -e  's/<\/td>//'`
   res=${res}${part}

  fi

 fi
}
echo $res | sed -e 's/amp\;//g' -e 's/ //g' 

Here is the table I used:

Tool to manage power for ppc Linux

ACPI is n/a for ppc. Same for apm. Those don't work with the ppc hardware. Pbbuttonsd controls sleep and hibernate. And for PPC Linux, you must have an ATI graphics card for sleep to work. Nvidia and anything else will not work.



$ sudo pbbcmd hibernate

or

$ sudo pbbcmd sleep

or

$ sudo pbbuttonsd sleep
