Filesystems, Disks and Memory

Hi,

Can any one tell me how to find the growth of a file (monitor).

Using a simple pipeline you can get the current size of a file. Wrapping that in a script and setting a threshold would allow you to trap a file size. The following examples were executed in ksh on a Solaris 8 system but should be sufficiently generic:

Code:

$ ls -l /var/log/syslog 
-rw-r--r--   1 root     root        4109 May 18 07:30 /var/log/syslog
$ ls -l /var/log/syslog | tr -s " " "\t" | cut -f5
4109

Save that as a variable and compare:

Code:

FILESIZE=$(ls -l /var/log/syslog | tr -s " " "\t" | cut -f5)

if [ $FILESIZE -lt 10000 ]
then
    :   # no action required
else
    echo "$FILESIZE" | mailx -s "file limit reached" root
fi

And as my grandmother always said, "season to your taste." I hope this helps.
