I intentionally did not specify html programming in the topic, since web programming can take several forms.
Please post your web programming tip, tricks or questions here.

Here is a script that will generate an html index of directories and files.
| Code: | #!/bin/sh
# $1 is a directory to index as html
cd $1;
for x in *; do [ -d "$x" ] && D=$D"<li><a href=\"$x/\">$x/</a></li>" || F=$F"<li><a href=\"$x\">$x</a></li>"; done
echo "<html><head><title>index of $1</title></head><body><p><b>index of $1</b></p><p>directories:</p><ul><li><a href=\"../\">[parent directory]</a></li>$D</ul><p>files:</p><ul>$F</ul></body></html>" >$1/index.html |
there is a C version of this script here:

Hey trapster
| Quote: | | Not working well with spaces in file names. |
this will auto fix /heal all folders and files with spaces or symbols and convert them to underscore "_"
just place it in the folder with the bad names and run it
all is automatic
Joe
| Code: |
#!/bin/bash
# Joe Arose version 1.05
# sana_auto = auto find and repair
# sana = sanitize these =;:"`<>,!@#$?%^*&(){}[]
# sana = sana sana colita de rana "for the spanish translation"
# drag N drop rename files that have been badly named
# to a corrected format with underscores
# many bad characters get deleted
# programs will not function correctly with spaces placed in the name
# note that permissions are preseved !
rm -f /tmp/sanitized
rm -f /tmp/borked_name

big_bass -
Thanks for the offer and I will save this for future use but I have 6,000 songs + movies already running on my server and I don't want to mess with the filenames.
I do use "tree" to create an html file index.
ie:
| Code: | | tree -a -H /mnt/home/music > /mnt/home/music/index.html |
Works a treat.

Hey technosaurus ,trapster
well here is a real simple basic index maker and easy to edit
for anyone to hack at
| Code: |
#!/bin/sh
#code from Joe Arose big_bass built for special use
# generate a custom index
# drag N drop a folder on the script
#with the end goal of easily making the correct formatting
#simple and clean
#as just the URL's then generate a new index
#/root/new_index_list #this is the index generated
#---------------index maker--------------------------------
echo '
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<html>
<head>
<title>Index of </title>
</head>
<body>
<h1>Index of new_index_list</h1>
<pre><img src="/usr/local/lib/X11/pixmaps/archive48.png" alt="Icon "> <a href="?C=N;O=D">Name</a>' >/root/new_index_list
for i in `find "$@"/*`
do echo "<"a href="$i"">"$i"<"/a">" >>/root/new_index_list
done
echo '<hr></pre>
<address>Apache Server at distro.ibiblio.org Port 80</address>
</body></html>' >>/root/new_index_list
#you can edit this if you have seamonkey
#gtkmoz /root/new_index_list
/usr/lib/firefox/firefox /root/new_index_list

Use this to remove spaces:
| Code: | | for x in *; do X="`echo $x|tr ' ' '_'`";[ "$x" != "$X" ] && mv "$x" "$X"; done |
I used * to fix the initial version too - so it should allow spaces when I repost it

Hey technosaurus
I liked the visual output of the generated code you did nice job 
It however was difficult to read the source code
I combined my code with yours to have both
the source and the output pretty 
thanks for starting this thread
and posting your code
Joe
*this takes more lines of course but the byte count is still very low
EDIT filter for files so folder isnt made for directories also
| Code: |
#!/bin/sh
# drag N drop html index maker
# "$@" is a directory to index as html
# technosaurus author
# big_bass improved generated source code readability
cd "$@"
#---------------------
# clean up old debugging files
#---------------------
rm -f "@"/index.html
rm -f /tmp/flist2
rm -f /tmp/dlist2
#---------------------
# generate the directory and file index
#---------------------
for x in *
do [ -d "$x" ] && echo "<li><a href=\"$x/\">$x/</a></li>" >> /tmp/dlist2
! [ -d "$x" ] && echo "<li><a href=\"$x\">$x</a></li>" >>/tmp/flist2
done
#---------------------
# Head make the html head
#---------------------
echo "<html><head><title>index of "$@"
</title></head><body><p><b>index of "$@"</b>
</p><p>directories:</p>
<ul><li><a href=\"../\">[parent directory]</a>">"$@"/index.html
#---------------------
# Body append the dynamic info for the index here the (directories )
#---------------------
echo "</li>" >>"$@"/index.html
cat /tmp/dlist2>>"$@"/index.html
echo "</ul>">>"$@"/index.html
#---------------------
# Body append the dynamic info for the index here the (files )
#---------------------
echo "<p>files:</p><ul>" >>"$@"/index.html
cat /tmp/flist2 >>"$@"/index.html
echo "</ul>" >>"$@"/index.html
#---------------------
#Close the html header
#---------------------
echo "</body></html>" >>"$@"/index.html
# remove new debugging files
#rm -f /tmp/flist2
#rm -f /tmp/dlist2

Normally I would do the same, but wanted the code to be as fast as possible in case it's used as a cgi script - thus only one loop, one check and one echo... but I could probably add some return characters and/or backslashes for readability without affecting the speed.

Just make sure you are currently running mysql from your box with existing database and table inside.
First, launch your favorite linux editor and create a bash script and paste the following bash codes inside and save.
| Code: | #!/bin/bash
# july 03 2007 – vertito
# this script retrieves data from mysql using bash
dbase=`mysql -uMYSQLUSENAME -pMYSQLPASSWORD -e”use MYDATABASE; select * from MYTABLE where id = 1;”`
for data in $dbase ;
do
echo $data
done
echo Done.
#chmod 700 yourscript.sh
#./yourscript.sh
|
Works like a charm!
Dont forget to change the following wordings:
MYSQLUSERNAME = your mysql username access with your mysql server
MYSQLPASSWORD = your mysql password
MYDATABASE = your running mysql database name
MYTABLE = your selected table name |

having code examples are great when they can be recycled
what is worth more than any code snippet in itself
is the educational value it has
if you can learn something from the code it is useful
In my opinion
good documentation is worth more than the original work itself
because it invites creativity and growth

Hey technosaurus
I recycled the code some more to take a plain text file as input
I dont have direct access to the folder /files on the server to dragndrop the file to build the index
I had earlier written my own indexing for my packages
I was happy with it but the rendering of the page was slow
due to the images and so I decided to go simple and clean
and re do it
*I had written a way to auto generate package sizes and the dates
but that only works when you have all the files on your box 
if you (or any one else )see(s) something you would change / improve let me know
if you take a look at the link http://www.puppy2.org/slaxer/
here is a simple new index waiting on improvements
thanks
Joe

... good idea for adding file size
need to change this:
F=$F"<li><a href=\"$x\">$x</a></li>"; done
to something like this:
F=$F"<li><a href=\"$x\">$x</a> `du $x` kb</li>"; done

I just made two strings
$datemodified
$size
here is only an example I dont use the echoes
and the package is "x"
just wanted to post a stand alone snippet
awk is nice to get exactly what you want from the output
and this also displays in MB or KB automatically
| Code: |
# use any package for a test
package="/root/qemu-0.91-launchscript-SDL-1.29-i486-3_SLXR.txz"
datemodified=`ls -lh "$package" | awk '{ print $6 }'`
size=`ls -lh "$package" | awk '{ print $5 }'`
echo $datemodified
echo $size
