TZ means time zone.... and MYT is your local time.. 16 is difference from GMT to get yesterday date...
and your are taking it into variable so it would not override default time zone.

you can run in cron also but i am not very familier with cron.

Hi Sandeep,

i will get the flatfile from my server to another server which reside in my country also, so do i need to follow GMT?
let say i run the cronjob at oct 10 at 4 am, can i set the TZ=MYT+6, which is oct 9?

you can use the TZ variable to match your server timings.. but if you want exactly the same time and date yesterday, you have to use TZ=MYT+16..

if i am not wrong MYT is malaysian time... if it is GMT+8hrs... now to get Ydate you need to use MYT+(24-8).

jus send the output of "date" command and "echo `TZ=MYT+16 date`"

if you directly use TZ=MYT+16 date at prompt , your default time will be override because TZ is a environmental variable. so better to take into some temp variable.

i hope i was clarified.

Hi Sandeep,

i got 1 more last question, my shell script as below: If i run it thru cronjob everyday, will it override my default time zone? Also what is mean by temp variable?

YDAY=`TZ=MYT+12 date '+%Y%m%d'`

quote USER $USER
lcd $LDIR
mget $FILE$YDAY*.txt
exit 0

what i mean by temp variable is nothing but YDAY in your script.. and your default time zone will not be override as your are using now.

and in script ftp block might not work.. Replace with below block and try

ftp -inv $HOST <<END_SCRIPT
cd $LDIR
mget $FILE$YDAY*.txt
