I have a query here, following are the points on same(Adding today's is 31st August 2016 for future reference).
1st Scenario: So while doing some work on GNU date, I wanted to check what was the month(in numbers) by GNU date so I have done following.
Above gives me output as follows. 2nd Scenario: When I check this in terms of days then following is the result.
So after executing above scenarios I felt like if as a user I do -2 months with GNU date then it should ideally provide me month June, because when I do date -d"-3 months" +%m%d it shows me 0531.
So what is my observation is even we do -month option with GNU date in backend it will count by days only, if I am right here, so isn't it something kind of bug etc or it is expected behavior.
Will be grateful to all for your suggestions and advices here.
NOTE: testing it in BASH and version is date (GNU coreutils) 8.4.
Thanks,
R. Singh

I know there are some posts on getting the time with milliseconds included and I realize unix may not be the best on this.

How could I get a date's day of the week (ie Sunday) without using the date -d command?
So if a date was specified, it would give me the day of the week.
The date -d command looks something like this
date -d $inputdate | cut -c 1-3
the only problem with that statement is that it won't... (2 Replies)
I have been out of the UNIX World for a number of years and none of my reference books seem to be helping e with this seemingly simple question. How can I manipulate the below command to reflect the previous day and not the current date?

Should work in any shell, but requires GNU date, although GNU date seems only to be happy for input dates between 1902 and 2037, inclusive (49673 days).
Assume $a and $b hold two dates, e.g.
set a=2010-03-27
set b=2010-04-04
Marginally faster:
iterator: seq -f "$a +%1.0f days" 1 50000 |... (0 Replies)
Hello everybody,

Dear all,
This should be simple but I cannot figure it out despite reading all the man pages. Could someone please help me translate this code (GNU date) to one that can be read by BSD date?:
myDate=$(date -d "$h -$l days" +%Y/%m/%d),
where h is a variable of the form DD/MM/YYYY, and l is... (3 Replies)
It's easy as pie to get the date minus one day on opensolaris:
date -d "-1 day" +"%Y%m%d"run this command on our crappy Solaris 10 machines however (which I'm guessing doesn't have GNU date running on it) and you get:

date: illegal option -- 1

So as I write this today is two days after the clocks go back here in the UK. I have a script that worked last week. Yesterday it developed a bug. I eventually found the culprit is Gnu Date.

touch
TOUCH(1) User Commands TOUCH(1)NAME
touch - change file timestamps
SYNOPSIS
touch [OPTION]... FILE...
DESCRIPTION
Update the access and modification times of each FILE to the current time.
A FILE argument that does not exist is created empty, unless -c or -h is supplied.
A FILE argument string of - is handled specially and causes touch to change the times of the file associated with standard output.
Mandatory arguments to long options are mandatory for short options too.
-a change only the access time
-c, --no-create
do not create any files
-d, --date=STRING
parse STRING and use it instead of current time
-f (ignored)
-h, --no-dereference
affect each symbolic link instead of any referenced file (useful only on systems that can change the timestamps of a symlink)
-m change only the modification time
-r, --reference=FILE
use this file's times instead of current time
-t STAMP
use [[CC]YY]MMDDhhmm[.ss] instead of current time
--time=WORD
change the specified time: WORD is access, atime, or use: equivalent to -a WORD is modify or mtime: equivalent to -m
--help display this help and exit
--version
output version information and exit
Note that the -d and -t options accept different time-date formats.
DATE STRING
The --date=STRING is a mostly free format human readable date string such as "Sun, 29 Feb 2004 16:21:42 -0800" or "2004-02-29 16:21:42" or
even "next Thursday". A date string may contain items indicating calendar date, time of day, time zone, day of week, relative time, rela-
tive date, and numbers. An empty string indicates the beginning of the day. The date string format is more complex than is easily docu-
mented here but is fully described in the info documentation.
