convert text file to html ouput so that data can b…

I have a text file which has 3 values separated by :

25-08-2019_19.00.00 : Port port1 of URL http://ip1:port1/ is  NOT OPEN :  Zoom1
25-08-2019_19.00.00 : Port port2 of URL http://ip2:port2/ is  NOT OPEN :  MP

and so on. I want to print the output to a html type tabular format file, which has 3 headings, date, output and system and corresponding data in 3 columns.

I tried below code, but it is not putting data to table format.

#! /bin/bash

if [ $# -eq 0 ] ; then
   echo "USAGE: $(basename $0) file1 file2 file3 ..."
   exit 1
fi

for file in $* ; do
   html=$(echo $file | sed 's/.txt$/.html/i')

   echo "<html>" >> $html
   echo "<style type="text/css">
        table, th, td {
        border: 1px solid black;
        }
        </style>" >> $html
   echo "   <body>" >> $html
   echo '<table>' >> $htm
   echo '<th>HEADING1</th>' >> $html
   echo '<th>HEADING2</th>' >> $html
   echo '<th>HEADING3</th>' >> $html

   while IFS=':' read -ra line ; do
    echo "<tr>" >> $html
    for i in "${line[@]}"; do
       echo "<td>$i</td>" >> $html
     # echo "<td>$i</td>" >> $html
      done
     echo "</tr>" >> $html
   done < $file
    echo '</table>'
    echo "   </body>" >> $html
    echo "</html>" >> $html
done

Answer

If you can, please consider awk:

awk -F' : ' '
  BEGIN{
    print "<html><style type="text/css">table, th, td {border: 1px solid black;}</style><body><table><th>HEADING1</th><th>HEADING2</th><th>HEADING3</th>"
  } 
  {
     print "<tr>"
     for(i=1;i<=NF;i++) 
       print "<td>" $i "</td>"
     print "</tr>"
  }
  END{
    print "</table></body></html>"
  }
' input_file > output.html

The BEGIN and END statement fills the static html tags.

The middle statement fills one line of the array according to each input file line by adding <tr> for each line and <td> for each field.
