jfs_fscklog – extract a JFS fsck service log into a file and/or format and display the extracted file
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.
Options
- -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 actual device from which the fsck log will be extracted (e.g. /dev/hdb1 )).
- -f file.name
- Specify the file name, overriding the default file name. When used with -e device, file.name specifies the name of the file into which the JFS fsck log will be extracted. When used with -d, file.name specifies the name of the extracted file whose contents will be formatted and displayed.
- file.name must be 127 characters or less in length.
file.name will be created in the present working directory unless it is fully qualified.
- file.name must be 127 characters or less in length.
- -p
- Extract the prior log (as opposed to the most recent log).
- -V
- Print version information and exit (regardless of any other chosen options).
Examples
- jfs_fscklog -e /dev/hda5
Extract the most recent JFS fsck log on /dev/hdb3 into /temp/l9651107.log:
- jfs_fscklog -e /dev/hdb3 -f /temp/l9651107.log
Display the JFS fsck log that was extracted into /temp/l9651107.log:
- jfs_fscklog -d -f /temp/l9651107.log
Extract and display the previous JFS fsck log from /dev/hda8:
- jfs_fscklog -e /dev/hda8 -d -p
