Date Function in UNIX

[davidku]

Hi Gurus,

I am writing a script to automatically mget ( ftp ) files from a remote server to my local machine.

xfile="datafile_`date +%y%m`*"

in my FTP script, I'll just mget $xfile

The problem I am facing is ... I need to retrieve data files for DAY - 1.

I can get the DAY variable and then -1 from it but it requires a lot of logic when comes to month end.

Example :

mget datafile_030604*

Let's say, today is MARCH 1st. 01 is my day and I cannot be the day set to 0.

Just want to check with you guys any idea how I can simplify this task ?

Thanks a lot ...

Here's a useful bit of code (and construct) for Korn Shell that I use here in the UK, to get date (and time) information 'in the past':

saved_TZ="${TZ}"
export TZ="GB+24:00"   # this is for 24 hours ago in GB Timezone
date_code=`date`
export TZ="${saved_TZ}"

I hope that helps.

Mike
