Full Discussion: Delete file by date or by size
Special Forums Hardware Filesystems, Disks and Memory Delete file by date or by size Post 17412 by Cameron on Thursday 14th of March 2002 06:00:54 PM

One suggestion may be that every 10 days that you swap files.
Hence you'd have two files at anyone time providing 20 days of log details (~/LogFile-A & ~/LogFile-B). Every 10 days swap between the two...for instance.

1/ Currently on LogFile-A
2/ 10 Days later swap to LogFile-B
3/ 10 Days later empty LogFile-A and swap to LogFile-A
4/ 10 Days later empty LogFile-B and swap to LogFile-B
5/ ** Keep rotating through steps 3 & 4.

Just a thought.

any command that will help me to limit the size of the log file to about 10,000 lines
Try: cat LogFile-A | wc -l

resize_lfs

RESIZE_LFS(8)						    BSD System Manager's Manual 					     RESIZE_LFS(8)

NAME

     resize_lfs -- resize a mounted log-structured filesystem

SYNOPSIS

     resize_lfs [-v] [-s new-size] mounted-file-system

DESCRIPTION

     resize_lfs grows or shrinks a mounted log-structured filesystem to the specified size.  mounted-file-system is the name of the filesystem to
     be resized, and new-size is the desired new filesystem size, in sectors.  If new-size is not specified, resize_lfs will default to the cur-
     rent size of the partition containing the filesystem in question.

     When growing, the partition must be large enough to contain a filesystem of the specified size; when shrinking, resize_lfs must first
     ``clean'' the segments that will be invalid when the filesystem is shrunk.  If this cleaning process results in these segments becoming
     redirtied, this indicates that the given new size is not large enough to contain the existing filesystem data, and resize_lfs will return an
     error.

EXAMPLES

     To resize the file system mounted at /home to 32576 sectors:
	   resize_lfs -s 32576 /home

SEE ALSO

     fsck_lfs(8), lfs_cleanerd(8), newfs_lfs(8)

HISTORY

     The resize_lfs command first appeared in NetBSD 3.0.

AUTHORS

     Konrad Schroder <perseant@NetBSD.org>

BUGS

     resize_lfs should be able to resize an unmounted filesystem as well.
