Hi,

Stuck in the middle: as I have to calculate the date back to 180days
and remove the files for a particular directory.

So, please help me in this regards.

Server : E250 Ultra m/c with OS: Solaris 9
TZ=US/Eastern

I tried but failed to get the o/p:

BackDate=`$TZ+2160 date "%Y %m %d %h"`

Thanks in Advance!

(csh/tcsh)
% env TZ=$TZ+4320 date
Friday September  5 16:12:43 Canada/Eastern 2003

(sh)
% TZ=$TZ+4320 date
Friday September  5 16:14:05 Canada/Eastern 2003

By far, the easiest thing to do here is just to install GNU date
somewhere, and use its date string parsing functions. 

$ /usr/local/bin/date --date "180 days ago"
Fri Sep  5 10:18:08 CDT 2003

This doesn't work in Solaris 9 (with current patches, anyway). The
offset is limited to 167:59:60 (i.e. one week) and if it is larger
the TZ variable is simply ignored.

Of course, there wasn't really ever any point in specifying
TZ=$TZ+4320 rather than, say, TZ=FooBar+4320. The offset is
always from UTC (GMT) with the name part just appearing at thn
timezone in the output.

There are some possibilities in the comp.unix.shell FAQ at

http://home.comcast.net/~j.p.h/cus-faq.html#G

Look at subsection g.

Try:

find /dirname/* -mtime +179

for all files modified 180 days or more ago. If you need files exactly
180 days ago, use this command for all files less than 180 days old:

find /dirname/* -mtime -181

and then use uniq to find files common to both find outputs. You may
have to tweak the values 179 and 181.

find /dirname -mtime +179 -mtime -181

would be a great deal simpler, although with these particular numbers
that's in fact equivalent to

find /dirname -mtime 180

Chris, your solution is more elegant. Especially if files modified
between two arbitrary dates are required. I did not know -mtime could
be used twice on the same find.
