       and display the extracted file


       jfs_fscklog [ -d ] [ -e device ] [ -f output.file ] [ -p ] [ -V ]


       jfs_fscklog with option -e device extracts the contents of  either  the
       most  recent  or  immediately prior (specified with option -p) JFS fsck
       service log from the specified device, and writes the output to a file.
       The  file name may be specified with the -f option, or the default file
       name is <pwd>  If the -p option is used, the  default  file
       name is <pwd>fscklog.old.

       jfs_fscklog  with  option  -d  formats and displays the contents of the
       extracted file.

       jfs_fscklog with options -d and -e device extracts and displays the JFS
       fsck service log.


       -d     Format  and display a previously extracted JFS fsck service log.

       -e device
              Extract the JFS fsck service log from device and store it  in  a
              file.   (device  is  the  special file name corresponding to the

              /dev/hdb1 )).

              Specify  the  file name, overriding the default file name.  When
              used with -e device, specifies the name  of  the  file
              into  which  the JFS fsck log will be extracted.  When used with
