SYNOPSIS
jfs_fscklog [ -d ] [ -e device ] [ -f output.file ] [ -p ] [ -V ]
DESCRIPTION
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>fscklog.new. 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.
