Another Date Question - Sorry
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?

the command is:


elm -s “SAP prs for `date '+%m/%d/%y'`” james.mcrae@dla.mil < chk_prs.txt

I have looked on this forum and found some -d options but I can't seem to get them to work.

Thanks in advance!!!

Try:

Code:
date -d "Yesterday"
date -d "1 Day ago"

Or you can manipulate with TZ variable to get previous day

Thanks for replying
Dennis,

OK.... here is what I submitted...

elm -s “SAP prs for `date -d “yesterday” '+%m/%d/%y'`” james.mcrae@dla.mil < chk_prs.txt

I got an error saying that -d is not a "legal option". Do I have the command formatted correctly?

Thanks again!!

There is a problem with date examples in posts. Linux users have a version of date with non-standard bells and whistles and -d is one of those. You don't have the same version as the poster.

Search the forum for 'yesterday date' or go to the FAQ and look at the 'Date Arithmetic' thread. You want to look at Perderabo's datecalc script. Date manipulation is probably the #2 question most frequently asked question here.
