Help needed to finish script

[Rudi Martin]

Hi there people

This command is part of a script I'm busy with -
cp /sdata/files/log/sabscan.l09 /sjtds/home/sabfiles/plp13.`date '+%d%m%y'`

Now , the sabscan.l09 file is an ever increasing , master file , but I need to add a command to my line that will only remove all the day's stuff and put it into the new plp12.(today's date) file. The command cannot use a specified date , as this is gonna run in a cron daily , so it's gonna update and create files daily.

Please help me URGENTLY !!!

Thank you

How about:
touch /sjtds/home/sabfiles/plp13.`date '+%d%m%y'` {create empty new daily file}

cat /sdata/files/log/sabscan.l09 >> /sjtds/home/sabfiles/plp13.`date '+%d%m%y'` {append data to new file}
cat /dev/null > /sdata/files/log/sabscan.l09 {empty master file}

Hi,

Is there a date entry is tyhe master file? if so you can do issue a date command that has the same output as in the file and do a awk script that prints all entrys after the date string and redirect it to todays file.

so:
VAR=$(date '+%d%m%y)
cat /sdata/files/log/sabscan.l09 | awk -v date=$VAR '/$VAR/ {start=1}
start=1 {print}'>>/sjtds/home/sabfiles/plp13.`date '+%d%m%y'`



HTH,

PS. did not test this so may need to make adjustments to get it working.

This isnæt possible without knowing if your file has a date in it and which format that date is in. If each line in your file has "month day" then you would only need to

grep `date +"%m %d"` /sdata/files/log/sabscan.l09 > /sjtds/home/sabfiles/plp13.`date '+%d%m%y'`

However, if there is no date in there at all then you are going to have to set up a cron job that moves sabscan.l09 to a backup file every day. Something like this

cat sabscan.l09 >> sabscan.l09.history && > sabscan.l09

Then you can use your normal script as sabscan.l09 will only ever contain todays data and sabscan.l09.history will contain all your previous days informatio

Thanx Mark

grep `date +"%d%m% y"` /sdata/files/log/sabscan.l09 > /sjtds/home/sabfiles/plp13.
`date '+%d%m%y'`

working like a bomb !

Cheers
