Ross:
Actually, this solves the problem nicely. I can always find an oracle database up around here somewhere :) A couple of folks suggested this approach and I was going to work on it yesterday when chaos broke out. But you were kind enough to give me the code! It's very much appreciated.
Thanks!

#!/bin/ksh
YESTERDAY=`sqlplus -s / <<-EOF
set head off feed off pages 0
select to_char(sysdate-1,'fmDy') from dual; exit
EOF`
TODAY=`date +\%a`
echo "TODAY is $TODAY YESTERDAY is $YESTERDAY"

Hth,

Will someone take pity on this poor VMS'er lost in a unix world??

I'm trying to create a script (ksh) that reads a log file created yesterday. The log files are created with `date +%a` appended to the end of the log file name. Last night a log file was created called arc_indexlog.Tue It's easy enough to get today

TDAY="`date +%a`"
grep -i "ora" /orasrv/ops/maint/logs/arc_indexlog.$TDAY grep -i "ora" /orasrv/ops/maint/logs/adv_indexlog.$TDAY

but how do I get yesterday in the same format? (i.e., Tue instead of Wed) I man'd date, but it was no help.

Thanks for any help.

Barb
