The problem you have is at the first of the month. (day - 2) does not work when today is the 1st or 2nd. The command "date '2 days ago'" does not work with the standard Unix date command. That syntax is a part of the GNU version of date. I would recommend installing it as it seems to be 100% backwards compatible with the vanilla date command but, as you can see, adds much more functionality. It is a part of the
coreutils package from GNU. Once you have this then SriniShoo's examples should work. I like to install this and call it gdate just to make sure to keep the original date command in tact.
There is also a shell script you can find on this site written by Perderabo which also does some pretty good date handling called
datecalc. I like the GNU date a little better but, just in case you cannot install 3rd party software, datecalc is a pretty close second.

The /var/adm/messages in Solaris seem to log more system messages/errors compared to /var/log/messages in Linux.
I checked the log level in Linux and they seem OK.
Is there any other log file that contains the messages or is it just that Linux doesn't log great many things? (2 Replies)

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.
