如果你有GNU日期，我理解正确

$ date +%Y:%m:%d -d "yesterday"
2009:11:09

or

$ date +%Y:%m:%d -d "1 day ago"
2009:11:09

好吧，这是一个晚的答案，但这似乎是有效的!

     YESTERDAY=`TZ=GMT+24 date +%d-%m-%Y`;
     echo $YESTERDAY;

#!/bin/bash
OFFSET=1;
eval `date "+day=%d; month=%m; year=%Y"`
# Subtract offset from day, if it goes below one use 'cal'
# to determine the number of days in the previous month.
day=`expr $day - $OFFSET`
if [ $day -le 0 ] ;then
month=`expr $month - 1`
if [ $month -eq 0 ] ;then
year=`expr $year - 1`
month=12
fi
set `cal $month $year`
xday=${$#}
day=`expr $xday + $day`
fi
echo $year-$month-$day

试试下面的代码，它也处理DST部分。

if [ $(date +%w) -eq $(date -u +%w) ]; then
  tz=$(( 10#$gmthour - 10#$localhour ))
else
  tz=$(( 24 - 10#$gmthour + 10#$localhour ))
fi
echo $tz
myTime=`TZ=GMT+$tz date +'%Y%m%d'`

何赛义工

date --date='-1 day'

date +%Y:%m:%d|awk -vFS=":" -vOFS=":" '{$3=$3-1;print}'
