Hey everyone!
I hope someone here is good with Unix CGI scripts.
I'm having trouble with my CGI. Here's the deal
I've created a program that searches the passwd file and cuts the users real name when it's given the login name. When i converted it to CGI i ran into some problems:
1) when you put one login name in, it echo's a statement (user is online/offine) 6 times! BUT when you put 2 or more, there is no repeating.
2) i dont think $* works when doing for loop. i had to hard code up to 6 variables (could be more though)
can anyone offer any help? I also ported this into an HTML version, but still have the same problems. (could have swore i had this working, but when i saved the HTML one, i over wrote the working one, and i forgot what changed i made )
I think it's my quotes but i'm not really sure anymore lol
here's my code:
Code:
#!/bin/sh
echo "Content-Type: text/plain"
echo ""
slice=`echo $QUERY_STRING|cut -d= -f2`
if [ "$slice" = "" ]; then
echo Please go back and enter a login name
fi
name1=`echo $slice|cut -d+ -f1`
name2=`echo $slice|cut -d+ -f2`
name3=`echo $slice|cut -d+ -f3`
name4=`echo $slice|cut -d+ -f4`
name5=`echo $slice|cut -d+ -f5`
name6=`echo $slice|cut -d+ -f6`
names="$name1 $name2 $name3 $name4 $name5 $name6"
for name in $names
do
who | grep $name > /dev/null
if [ $? = "0" ]; then
echo "Yes `grep "$name" /etc/passwd | cut -f5 -d:` is online"
else
echo "No `grep "$name" /etc/passwd | cut -f5 -d:` is offline"
fi
done
AAAHHH!! I've made a perl program that you can run on a web browser. This program needs to be run everyday, and I don't want to have to run it everyday. The problem is when I try running the program from my terminal, all it does is print stuff to the terminal page (the program involves a lot of... (4 Replies)
If I have a Perl CGI script (script01), which fills an array(s) with information and outputs a HTML page with a link to another CGI page (script02); is there anyway to pass the array(s) from "script01" to "script02" when the page visitor clicks the link?
Hope that makes sense!

plack::app::cgibin
Plack::App::CGIBin(3pm) User Contributed Perl Documentation Plack::App::CGIBin(3pm)NAME
Plack::App::CGIBin - cgi-bin replacement for Plack servers
SYNOPSIS
use Plack::App::CGIBin;
use Plack::Builder;
my $app = Plack::App::CGIBin->new(root => "/path/to/cgi-bin")->to_app;
builder {
mount "/cgi-bin" => $app;
};
# Or from the command line
plackup -MPlack::App::CGIBin -e 'Plack::App::CGIBin->new(root => "/path/to/cgi-bin")->to_app'
DESCRIPTION
Plack::App::CGIBin allows you to load CGI scripts from a directory and convert them into a PSGI application.
This would give you the extreme easiness when you have bunch of old CGI scripts that is loaded using cgi-bin of Apache web server.
HOW IT WORKS
This application checks if a given file path is a perl script and if so, uses CGI::Compile to compile a CGI script into a sub (like
ModPerl::Registry) and then run it as a persistent application using CGI::Emulate::PSGI.
If the given file is not a perl script, it executes the script just like a normal CGI script with fork & exec. This is like a normal web
server mode and no performance benefit is achieved.
The default mechanism to determine if a given file is a Perl script is as follows:
o Check if the filename ends with ".pl". If yes, it is a Perl script.
o Open the file and see if the shebang (first line of the file) contains the word "perl" (like "#!/usr/bin/perl"). If yes, it is a Perl
script.
You can customize this behavior by passing "exec_cb" callback, which takes a file path to its first argument.
For example, if your perl-based CGI script uses lots of global variables and such and are not ready to run on a persistent environment, you
can do:
my $app = Plack::App::CGIBin->new(
root => "/path/to/cgi-bin",
exec_cb => sub { 1 },
)->to_app;
to always force the execute option for any files.
