Hi All,

I tried using awk one liner as below It worked fine for the first time when I ran it for the second time it did not

Code:
`cal |awk -v d="$(date +"%m %d %y")" 'BEGIN{split(d,a)} $0 ~ int(a[2]) {print a[1] $3 a[3]}'`

It calculated for the first time and second time when I ran it gave all 081313
Code:
082713'
08613
081313
082713

I want to get the tuesday's date of the current week, what if the current week starts with another month how do I do this Please help me out. I really appreciate your help

Regads,
raj

mhc(5)								File Formats Manual							    mhc(5)

NAME
mhc - Message Harmonized Calendaring system DESCRIPTION
This manual page documents briefly the mhc file format. This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page. FIELDS
Mhc file format is based on STD11/RFC822: Standard for the format of ARPA Internet text messages. In mhc file, the following extra header fields are used. X-SC-Day: Date of event in format yyyymmdd. You can specify multiple date with space separated like: X-SC-Day: 19990409 19990413 which means April 9th 1999 and April 13th 1999. X-SC-Time: Time of event in format hh:mm-hh:mm or hh:mm. For event which has no meanings about time, you can leave it empty in this field. X-SC-Duration: Period of event in yyyymmdd-yyyymmdd. You can omit start date or end date, like "19991121-". X-SC-Duration: is used only to limit date specified by X-SC-Day: or X-SC-Cond, so you can't describe event date only by X-SC-Duration:. If X-SC-Duration: is empty, it means no limit. X-SC-Cond: Condition of event date by using following keyword. 00-31 Day of month. 1st 2nd 3rd 4th 5th Last Week in month. Sun Mon ... Sat Day of week. Jan Feb ... Dec Month Examples, X-SC-Cond: Tue Fri Every Tuesday and Friday. X-SC-Cond: 31 Aug Every August 31th. X-SC-Cond: 1st 3rd Fri Every 1st and 3rd Friday. X-SC-Cond: Fri X-SC-Day: !19990409 Every Friday, but except April 9th 1999. X-SC-Cond: Fri 13 Every 13th and Every Friday, not 13th Friday. X-SC-Alarm: Hint for alarm of event. Currently, mhc.el doesn't alaram, but gemcal will pop-up alarm window. It will be useful if you transfer this event to PalmOS. In X-SC-Alarm:, you can specify the number (1 to 99) with suffix such as minute, hour or day. For example, X-SC-Alarm: 10 minutes Alarm 10 minutes before event. X-SC-Alarm: 3 hour Alarm 3 hours before event. X-SC-Alarm: 3 day Alarm 3 day before event. X-SC-Subject: Subject of event. unstructured? X-SC-Location: Location of event. unstructured? X-SC-Category Category of event. Any keyword, space separeated. Case ignored. X-SC-Recoard-Id: Internal use only. SEE ALSO
