frag - simple fragmentation checker
/sbin/frag [ -l ] [ -s [ -s ]] filename ...
frag will report the file system fragmentation on a specified filename.
If the filename is a directory, frag will recursively descend the
-l Long mode. Lists the start and end blocks of all fragments of
each file scanned.
-s Silent (may be set to 1 or 2). The first -s eliminates the file
by file statistics, and just prints the examined directories and
a summary. The second -s eliminates the printing of the
directories, and just prints a summary. This option is useful
when frag is used on a directory.
e2dump(8), xdump(8), defrag(8), mkfs(8), fsck(8), mkefs(8), efsck(8)
frag will get caught in an infinite loop in the /proc filesystem.
It is impossible to determine where a file’s meta-data resides on disk
simply by accessing the mounted file, so some apparent fragments
reported by frag may be simply the result of low-level index blocks on
disk. The e2dump and xdump programs can interrogate a partition
directly to access this data and to give more accurate results.
V1.0 by Werner Almesberger
V1.1 by Steffen Zahn, adding directory recursion
V1.2 by Rob Hooft, adding hole counts
V1.3 by Steffen Zahn, ignore symlinks, don’t cross filesys borders, get
filesystem block size at runtime
V1.4 by Stephen Tweedie, added indirect block support and improved
statistic summaries. Added "-l" switch.
