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.

strclean

strclean(8)						      System Manager's Manual						       strclean(8)

NAME

       strclean - Removes outdated STREAMS error log files

SYNOPSIS

       /usr/sbin/strclean [-d logdir] [-a age]

FLAGS

       Specifies  a  maximum  age  in  days for the STREAMS error log files if this not the default age of 3.  The value of age must be an integer
       greater than or less than 3.  Specifies a directory for the location of the STREAMS error log files to  be  removed  if	this  is  not  the
       default directory /var/adm/streams.

DESCRIPTION

       The  strclean  command cleans the STREAMS error logger directory of log files (error.mm-dd) that contain error messages sent by the STREAMS
       log driver (strlog).  If no other directory is specified (the logdir argument), the command removes error log files in the /var/adm/streams
       directory.  If no other age is specified (the age argument), the command removes error log files that have not been modified in 3 days.

       The strclean command is executed by the cron daemon on a periodic basis.

EXAMPLES

       To remove the day-old error log files from a directory called /tmp/streams, enter: strclean -d /tmp/streams -a 1

FILES

       One or more error log file or files on which strclean operates.	The mm.dd in the filename indicates the month and day of the messages con-
       tained in the file.

RELATED INFORMATION

       Commands: strerr(8), cron(8).
