Yesterday's date
Anybody know how too get yesterdays date ? Perhaps by manipulating the date command ?

Yep, date manipulation - the command:
date -v-1d will give you the date output reading of one day previous on a FreeBSD system. Probably similar on other Unices, man date. -Gary

% man date Read up on the commands that your date program supports. There should be an option for adjustment of varying degrees.

Don't know if the TZ (Timezone variable) is set in your environment. If so something like this will do the trick (I also don't have the -v option, or similar alternative, in date).
Code:
#!/usr/bin/ksh
# Name : pdate
# Purpose : Reports the date 'shift' hours from now, formatting is allowed
typeset -i X
if (( $# < 1 ))
then
print -u2 "Usage: $0 shift [ + format ]"
print -u2 "Reports the date 'shift' hours from now. Format as in date."
exit 0
fi
X=$1
F=$2
TZ=`echo $TZ | sed -e "s/MET-1/MET$((-1-X))/" -e "s/DST-2/DST$((-2-X))/"`
if [[ -z $F ]]
then
date
else
date "$F"
fi
You might need to change $TZ to your $Timezone variable (if one excists that is).
