Shell Programming and Scripting

before asking the command, you need to give your OS details.

Did you try my solution ?

Itkamaraj > Your solution is not giving the week code of a year. Week code of a year varies from 1 to 52. Hope you understand the requirement.

OS & platform:SunOS-sparc
OS version : 5.10

Please check your copy of man date. Your definition is more like date +%V which has range 01-53. Please do describe the rules for week number one.
e.g. According to ISO conventions 01/01/2012 this year is in week 52 of 2011. In date +%W it would be in week 00 of 2012.

Other posters have assumed that you have the GNU version of the date command which can do some date conversion. Without this program it is virtually impossible to achieve the desired result easily.

The Perl programmers may have a way. Similarly I've seen some pretty clever processing of the output of the cal command on this board.

Also (a db connection might be expensive or you may not have mysql on your system), another possibility is:

Code:

mysql -u <username> -p<password> -e "SELECT WEEK('2012-04-04');"

I refer you to the ISO definition of a week.
ISO week date - Wikipedia, the free encyclopedia

OK.

Hi,

Also have a look at this

YMMV

See
date(1): print/set system date/time - Linux man page

%G%V will give the year and week number

OK
