Full Discussion: korn shell script to keep history of same file
Top Forums UNIX for Dummies Questions & Answers korn shell script to keep history of same file Post 302092438 by BOFH on Monday 9th of October 2006 09:54:53 PM

Basically, save the current date to a shell variable like DATE

Code:
DATE=`date +"%Y%m%d"`

Move the file to the new file

Code:
mv log log.$DATE

And then just delete the files older than 14 days

Code:
find /var/adm -name log.* -exec rm {} \;

Of course you'll need to put some extra bits around the commands I gave you. I don't know your file name name or path. I don't know if the find will delete more than just the file you're interested in. I don't know if the program will continue to write to the moved file or if you'll need to create a new log file and restart the app. I don't even know the OS which might make a difference.

Since I don't know any other variables other than the bit you put out, these commands if executed as they sit now could cause some damage to your system. Make sure you appropriately modify them with file names and paths and check the subdirectories to make sure you don't delete a needed file.

strclean

strclean(8)						      System Manager's Manual						       strclean(8)

NAME

       strclean - Removes outdated STREAMS error log files

SYNOPSIS

       /usr/sbin/strclean [-d logdir] [-a age]

FLAGS

       Specifies  a  maximum  age  in  days for the STREAMS error log files if this not the default age of 3.  The value of age must be an integer
       greater than or less than 3.  Specifies a directory for the location of the STREAMS error log files to  be  removed  if	this  is  not  the
       default directory /var/adm/streams.

DESCRIPTION

       The  strclean  command cleans the STREAMS error logger directory of log files (error.mm-dd) that contain error messages sent by the STREAMS
       log driver (strlog).  If no other directory is specified (the logdir argument), the command removes error log files in the /var/adm/streams
       directory.  If no other age is specified (the age argument), the command removes error log files that have not been modified in 3 days.

       The strclean command is executed by the cron daemon on a periodic basis.

EXAMPLES

       To remove the day-old error log files from a directory called /tmp/streams, enter: strclean -d /tmp/streams -a 1

FILES

       One or more error log file or files on which strclean operates.	The mm.dd in the filename indicates the month and day of the messages con-
       tained in the file.

RELATED INFORMATION

       Commands: strerr(8), cron(8).

       Interfaces: strlog(7).  delim off
