Hi, please also show a representative sample of input, desired output and attempts at a solution.
Input (main.lst) could be something like this :
holidays.lst could be :
As balajesuri pointed out, I had already figured that I would first need to USE these dates as YYYYMMDD for numeric comparison/sort.
So, latest date in this case would be 01062012. This day happens to be a Friday but is in "holidays.lst". So, I add 1 to the date and get 02062012. This is a Saturday and not in the list. And that's my procdate.
In the second loop, I add 1 to procdate (no checking first). That gives me 03062012. Now this is a Sunday. So, again I add 1 to 03062012 to get 04062012. This is not a Sunday and not in the list. That's my finaldate.
Since I need to find the day of the week for a particular date, I feel this could be done with a combination of cal and awk (to get the field number). But, I am a total newbie with awk....
Hope that helps you to help me, Scrutinizer...

If current_date =01 Aug 2008 , then output= 31 July 2008
Please advice

Hi all,
I would appreciate if anyone knows how to perform adding to date.
As for normal date, i can easily plus with any number.
But when it comes to month end say for example 28 Jun, i need to perform a plus with number 3, it will not return 1 Jul.
Thanks in advance for your help. (4 Replies)

dp
DP(8) [nmh-1.5] DP(8)NAME
dp - parse dates 822-style
SYNOPSIS
/usr/lib/mh/dp [-form formatfile] [-format string] [-width columns] [-version] [-help] dates ...
DESCRIPTION
Dp is a program that parses dates according to the ARPA Internet standard. It also understands many non-standard formats, such as those
produced by TOPS-20 sites and some UNIX sites using ctime(3). It is useful for seeing how nmh will interpret a date.
The dp program treats each argument as a single date, and prints the date out in the official 822-format. Hence, it is usually best to
enclose each argument in quotes for the shell.
To override the output format used by dp, the -format string or -format file switches are used. This permits individual fields of the
address to be extracted with ease. The string is simply a format string and the file is simply a format file. See mh-format(5) for the
details.
Here is the default format string used by dp:
%<(nodate{text})error: %{text}%|%(putstr(pretty{text}))%>
which says that if an error was detected, print the error, a `:', and the date in error. Otherwise, output the 822-proper format of the
date.
FILES
$HOME/.mh_profile The user profile
PROFILE COMPONENTS
None
SEE ALSO ap(8), Standard for the Format of ARPA Internet Text Messages (RFC-822)
DEFAULTS
`-format' default as described above
`-width' default to the width of the terminal
CONTEXT
None
BUGS
The argument to the -format switch must be interpreted as a single token by the shell that invokes dp. Therefore, one must usually place
the argument to this switch inside quotes.
