xchklog(8)            JFS utility - extract fsck.jfs log            xchklog(8)



NAME
       xchklog - extract a log from the JFS fsck workspace into a file


SYNOPSIS
       xchklog [ -f output.file ] [ -p ] [ -V ] device


DESCRIPTION
       xchklog  extracts the contents of either the most recent or immediately
       prior JFS fsck service log from the specified device,  and  writes  the
       output  into  a  specified  or default file.  (The default file name is
       <pwd>fscklog.new.  If the -p option is used, the default file  name  is
       <pwd>fscklog.old.)

       The contents of the output file can be formatted into text by using the
       JFS utility xchkdmp.


       device is the special file name corresponding to the actual device from
       which the fsck log will be extracted (e.g.  /dev/hdb1 ).


OPTIONS
       -f output.file
              Specify  the output file name, overriding the default file name.

              output.file must be 127 characters or less in length.

              output.file will be created in  the  present  working  directory
              unless it is fully qualified.

       -p     Extract the prior log (as opposed to the most recent log).

       -V     Print version information and exit (regardless of any other cho-
              sen options).

EXAMPLES
        Extract the most recent log on /dev/hda5 into <pwd>fscklog.new:

              xchklog /dev/hda5


       Extract the most recent log on /dev/hdb3 into /temp/l9651107.log:

              xchklog -f /temp/l9651107.log /dev/hdb3


       Extract the prior log on /dev/hdb4 into <pwd>fscklog.old:

              xchklog -p /dev/hdb4
