If you have logrotation in place you may want to know if a log-switch happened. I did this by checking if the first line of a file is still the same. (Hopefully it's not an empty line ;-) ) ... like this:
Code:
LOGFILE=/DB2/db2diag.log
NEWFILE=${LOGFILE%.log}_$(date +%Y%m%d%H%M).log
CHKFILE=/var/scriptdata/db2diagline.dat
CHKFILE2=/var/scriptdata/db2firstline.dat
read FIRSTLINE_SAVED < $CHKFILE2
FIRSTLINE="$(head -n1 $LOGFILE)"if [ "$FIRSTLINE" == "$FIRSTLINE_SAVED" ] ; then
EndLine=$(awk 'END{print NR}' $LOGFILE)
if [ -f $CHKFILE ] ; then
read StartLine < $CHFILE
StartLine=${StartLine:-0}
# Test for log file truncated
[ $EndLine -lt $StartLine ] && StartLine=0
else
StartLine=0
fi
else
StartLine=0
head -n1 $LOGFILE > $CHKFILE2
fi
awk -vS=$StartLine -vE=$EndLine 'NR>E{exit} NR>S' $LOGFILE > $NEWFILE
#Save EndLine for StartLine next time
echo "$EndLine" > $CHKFILE

I need to copy the entire contents of one file into an existing file at a specific location. I know the exact line number where I need to put it. It appears I would use either sed or awk to do this, but I have been unsuccessful so far:
