calculate date=todate - 2 weeks

[Kurt Beyers.]

Hi,

I'm looking for a shell script that gives me the current date minus 2 weeks in the format YYYYMMDD.

The script would have to run finally on AIX 5.1 32bit.

regards,
Kurt

Maybe you could leverage from Clay's Date Hammer which is legendary here

How about this:

PREV14=$(caljd.sh -y -s $(caljd.sh -p 14))
echo "Date = ${PREV14}"

Invoke as caljd.sh -u for full usage.

Caljd.sh should run on AIX but change the "shebang" to ksh.

Clay's "date alarm" must be ringing off the wall by now. Just in case he's unavailable, I'll suggest that his perl version of caljd would probably fit the bill. It's available from Merijn's site: http://www.cmve.net/~merijn/#Contrib

here's a script that I wrote that looks at the logins for the past 2 months... some slight modifications to it will give you what you need.

Sir Clay!!!

THe other option is to use the Perl version; all the arguments are exactly the same simply substitute "caljd.pl" for "caljd.sh". THe Perl version even runs on PC (if you've installed freebie ActivePerl so AIX should be duck soup.

[Patrick Wallek]

Have a look for A. Clay Stephenson's caljd.sh or caljd.pl scripts. The caljd.pl should run fine on AIX if you have Perl installed. The caljd.sh may have to be slightly modified, but it should still run.

Thanks a lot for the fast and recursive redirections to the famous caljd.sh script of A. Clay.

Works like a charm on the HPUX 11.0 server here, I'll test it next week on the AIX server (don't have one now to test). But I'm confident that it will work over there as well.

The thread can be closed again ;-)
