UNIX Add OS Date to Filename

Oracle Database Tips by Donald BurlesonAugust 27, 2015

Add the UNIX date to an Oracle file name

UNIX allows the user to enter the date command to see the current date.  This command can be captured inside a UNIX script and use the date as part of the UNIX filename. 

The following shows how the UNIX date function with date masks can be used to change the display values according to user needs:

      YEAR=`date +"%Y"`
      MONTH=`date +"%m"`
      DAY=`date +"%d"`
      HOUR=`date +"%H"`
      MINUTE=`date +"%M"`

In some cases, the goal is to record the current UNIX date inside an Oracle log file.

 The following script places the date into a log file, indicating the exact time that a UNIX task ended:

echo End `date` > /usr/local/bin/scripts/logs/tar_end.lst

The following clever command uses the UNIX tee command in conjunction with the UNIX date command. 

It appends the current UNIX date and also uses the tee command to direct the output both to standard out as well as the progress.log file:

echo "Rebuild start for ${TABLESPACE}. . "\
     `date +"%H:%M "`|tee -a progress.log

The following handy UNIX script for check files with specific dates embedded in the UNIX file name. Once the files are written with the UNIX date, the UNIX files can be checked based on date.

The script below takes the current data and display all files in the /u01/backup/logs directory that have the current day and month.

mday=`echo $mdate|awk '{print $3}'`
mmonth=`echo $mdate|awk '{print $2}'`

echo  month $mmonth
echo  day $mday

ls -alt /u01/backup/logs|grep `echo $mmonth $mday`
