Hi,
I have created a convaluted and hacked script here for comparing unix dates.
Can someone help me use calc or date w/ julian param or something to look back a week, a month or even a year and compare dates or add/subtract the dates somehow in a shell script?
Hope this makes sense!
Thanks for any help or resources.
My script( I apologize if this example doesn't work right, I have been changing it and trying to make sense of it!):
#!/bin/bash
#Day of the week
DAT="`date +%w`"
#Current date
CDAT=`date +%Y-%m-%d | sed 's/-//g' | cut -c5-8 | sed 's/^0//'`
# Get DATETIME in this format: "2005-10-16 20:03:36" from IBM TSM Database - DB2
dsmadmc -id=admin -password=admin select 'DATE(LAST_WRITE_DATE)','TIME(LAST_WRITE_DATE)' from volumes where STGPOOL_NAME="'LTOPOOL2'" | grep -v -e IBM -e Copyright -e Tiv -e Comm -e Sess -e Serv -e ANS -e Vol -e VOL -e "---" -e LAST -e Unnamed | /bin/sed '/ *#/d; /^ *$/d' > $DATETIME
cat $DATETIME | awk '{ print $1; }' > $DBDATE
cat $DBDATE | cut -c6-10 | sed 's/-//g' | sed 's/^0//' | sort -u | uniq > $STRIPDATE
cat $DBDATE | cut -c6-10 | uniq > $DAYMONTH
for NUM in `cat $STRIPDATE`
do
if [[ `expr $CDAT - $NUM` = 22 || `expr $CDAT - $NUM` > 90 ]]
then
echo $NUM | sed -e :a -e 's/\(.*[0-9]\)\([0-9]\{2\}\)/\1-\2/;ta' >> $GETDAYMONTH
else
:
fi
done
cat $GETDAYMONTH | uniq >> $CALCDAYMONTH
for CNUM in `cat CALCDAYMONTH`
do
grep "$CNUM" $DATETIME | sed 's/ //' >> $ARCHHOLD
done
cat $ARCHHOLD | sed -e 's/./& /10' > $FINAL_ARCH
done
exit 0;
