Question variable used as filename
Hello, i'm fairly new to scripting, so please bear with me (I did try looking this up first, i figured it had to have been asked already).

Code:
#!/bin/bash
fileName=`date | sed -n 's/ /_/g p' | sed -n 's/^/Backup_/p' | sed -n 's/$/\.tar/p'`; #THIS SETS BACKUP_DATE
echo $fileName #TEST OF VALUE

tar -cf $fileName tmp/*;
#gzip tmp/$fileName;

the test of the value (4th line) works, so i know its not something silly like my permissions screwed up for the script. I commented out the last line because for some reason when the script gets to the tar part (2nd to last line) it just hangs. hitting <ctrl>c the script ends, and there's no tar in my directory. what am i doing wrong?

thanks a bajillion, in advance for your help!

modload

modload(1M)						  System Administration Commands					       modload(1M)

NAME

       modload - load a kernel module

SYNOPSIS

       modload [-p] [-e exec_file] filename

DESCRIPTION

       The modload command loads the loadable module  filename into the running system.

       filename is an object file produced by ld -r. If  filename is an absolute pathname then the file specified by that absolute path is loaded.
       If  filename does not begin with a slash (/), then the path to load  filename is relative to the current directory unless the  -p option is
       specified.

       The  kernel's modpath variable can be set using the /etc/system file. The default value of the kernel's modpath variable is set to the path
       where the operating system was loaded.  Typically this is /kernel /usr/kernel.

       For example, the following command looks for ./drv/foo:

	 example# modload drv/foo

       The following command looks for /kernel/drv/foo and then /usr/kernel/drv/foo:

	 example# modload -p drv/foo

OPTIONS

       The following options are supported:

       -e exec_file    Specify the name of a shell script or  executable image file that is executed after the module is successfully loaded.  The
		       first argument passed is the module ID (in decimal). The other argument is module specific. The module specific information
		       is: the block and character major numbers for drivers, the system call number for  system  calls,  or,  for   other  module
		       types, the index into the appropriate kernel table. See	modinfo(1M)

       -p	       Use the kernel's internal modpath variable as the search path for the module.
