'generating a directory listing as webserver index page in linux

I am using 

python -m SimpleHTTPServer 8080

to start a webserver from a linux directory. I am trying to write a shell script that generates a index.html page containing the following information : File Name( as a hyperlink ), File Size, Last Modified Date. So really a custom directory listing.

Here is the script which currently gets the correct info but displays all of it on a single line and doesn't hyperlink the filename. Can anyone direct me into the right direction?

    TITLE="Latest Logs"
    echo "<html>" > index.html
    echo "<title>$TITLE</title>" >> index.html
    echo "<body>" >> index.html
    echo "<h1>$TITLE</h1>" >> index.html
    ls -ctgGh | awk '{print $3 " " $4 " " $5 " " $6 " " $7}' \
    | grep -v index.html \
    | sed 's/[^0-9\s]+[.][^0-9\s]+/<a href="&">&<\/a><br\/>/g' \
    >> index.html
    echo "</body></html>" >> index.html

So what i am piping into sed is :

374,Nov 6,04:03,generate.sh
7.5M,Nov 6,04:00,Admin-server.log
46M,Nov 6,03:48,run1.log
528K,Nov 4,15:03,build.log

and i want to get :

375,Nov 6,04:14,<a href=generate.sh>generate.sh</a>
7.5M,Nov 6,04:09,<a href=Admin-Server.log>Admin-Server.log</a>
46M,Nov 6,03:48,<a href=run1.log>run1.log</a>
528K,Nov 4,15:03,<a href=build.log>build.log</a>

I think your first change should be not hard-coding the output filename into the script. Just output normally, to standard output, and when you call the script, use redirection.

For example, your line

echo "<html>" > index.html

should just be

echo "<html>"

but when you call the script, call it like this:

my-script > index.html

and the shell will put the output into the right file. (This is helpful when testing, too, if you want to put output into a test file.)

Assuming you're using sh, you should probably start your script with a "shebang":

#!/bin/bash

as the first line. See the Advanced Bash Scripting Guide for details.

Once you do that, you shouldn't need the 

grep -v index.html

in your script, because it shouldn't be present in the script's environment.

In your example input, you have commas, but in the real world, they would be spaces. Not a problem, just a correction to the question.

With awk, you can probably separate the fields with spaces by using commas, not " ". It would be more readable. And don't use sed; it's not necessary. You can make all your changes with awk:

awk '{print $3, $4, $5, $6, "<a href=" $7 ">" $7 "</a>"}'

should do the trick.

So the engine in your script will consist only of ls piped into awk, with echo giving the output some structure; and when you use the script, redirection will take care of getting it into a file.

#!/bin/sh
TITLE="Latest Logs"
echo "<html>" > index.html
echo "<title>$TITLE</title>" >> index.html
echo "<body>" >> index.html
echo "<PRE>" >> index.html
echo "<h1>$TITLE</h1>" >> index.html
ls -lrt | grep -v index.html | awk '{print $3, $4, $5, $6, "<a     href=http://10.77.28.119:9090/"$9 "<a>" $9 "</a>"}' >> index.html
echo "</pre>" >> index.html
echo "</body></html>" >> index.html

The above code generates an index.html file which when called from a browser page will show up all the files in the directory. You can replace the ip address with your web server ip address and port.
