Question

Wat exactly is the issue ?

Code:
[joe@Tux-Box ~]$ var=$(date)
[joe@Tux-Box ~]$ echo $var
Mon May 21 05:40:52 EDT 2012

This approach works.

Does the date command work at the command prompt?

EDIT:

If you put type date in the script on the line before var1=$(date), what is the output?

The "date is hashed (/bin/date)" looks good.

Is the "Mon May 21 16:28:32 BDT 2012" output from the script or from running the date command at the command prompt?

If you want to use it as a file name, it is better not to have blanks in it. date has many different formats here's just one:
Code:
 ]$ var1=$(date +%F); echo $var1
2012-05-21
]$

So, is the question about assigning a command value to a variable, or about date's formats? rabir, please clarify. If the latter, see the man page for info on how to format the output from date as you want.
