Yeah Bill, I do not want to reuse the TODAY variable external to the shell script, But what I want to say is When I echo $TODAY variable , it is not displaying the Data. myprompt$./storedate ./storedate: +%m/%d/%y: not found myprompt$

Hi , I wanna have a shell script which puts the today's date into a shell variable and later use the Shell Variable for other reasons, I have been using like this..
#!/bin/sh TODAY=date '+%m/%d/%y' echo $TODAY Can any one tell me what could be wrong in this...
Changing the date in your env will only change it for you and any child processes you create. Once your shell script exits, the TODAY will disappear for any new scripts run.
Where you do this: TODAY=date '+%m/%d/%y'
you need to do this: TODAY=`date '+%m/%d/%y'`
The back ticks will make the application execute to give you the value into TODAY.
I'd go down to the book store and locate either a used or a new book of the Linux Programming Bible for starter, and then maybe look for one specifically on shell programming in itself. I know there are some, but can't remember the names. I've seen them down at Borders.
I found one time using google a shell programming tutorial as well.
