Create variables from directory list problem

I am trying to take a list of directories in a folder and give them a variable name. I have this working with the exception that the shell_exec command wants to place a return. Here is my code which might explain better what I am trying to do:

PHP Code:


<?php

session_start();

$student1=$_SESSION['student1'];

$week1=shell_exec("ls /var/www/sad/ | grep 201 | awk 'NR>1{exit};1'");

$page = shell_exec("cat /var/www/sad/$week1/$student1/$student1.html");

echo "<pre>$page</pre>";

?>

I am not going to go into why I am trying to do this, but what ends up happening is the script tries to cat /var/www/sad/$week1 only because for some reason a return is held within the $week1 variable and it causes the script to treat /var/www/sad/$week1 and then $student1/$student1.html separately.

and I can't seem to figure out how to alleviate this problem.

I have tried:

Code:

ls /var/www/sad/ | head -1 | awk '{sub(/[ \t]+$/, "")};1'
ls /var/www/sad/ | head -1
ls /var/www/sad/ | awk 'NR < 2'

Everything places a return at the end of the string I am asking for. Any help is greatly appreciated.

packf

packf(1mh) packf(1mh)

Name
packf - compress a folder into a single file

Syntax
packf [ +folder ] [ msgs ] [ -file name ] [ -help ]

Description
Each message in a folder is normally stored as a separate file. The command takes all messages from the current folder and copies them to
a single specified file. Each message in the file is separated by four <CTRL/A>s and a newline.

You can specify a folder other than the current folder by using the +folder argument. If you do not want all the messages in a folder to
be packed into one file, you can specify a number of messages or a range of messages with message numbers.

The first message packed will become the current message. If you specify a +folder argument, that folder will become the current folder.

When messages have been packed into a file using you can separate them into individual messages using the command. See

Options
-file name
Specifies the file in which you want the message(s) to be stored. If you specify an existing file then the specified messages
will be appended to the end of that file. Otherwise, a new file will be created and the messages placed in it. If you do not
specify a filename, attempts to place the messages in a file called in the current working directory. If this file does not
exist, asks whether you want to create it.

-help Prints a list of the valid options to this command.

The default settings for this command are:

+folder defaults to the current folder
msgs defaults to all
-file ./msgbox

Examples
The first example shows all the messages in the folder being packed into a file called
% packf +lrp -file planning

The next example shows how prompts you if you do not specify a -file option. A file called is created by in your home directory, and mes-
sages 3 to 5 are packed into it:
% packf +lrp 3-5
Create file "/machine/disk/username/msgbox"? y
