-f Do not print the filenames for which extent
attributes are displayed.

-s Do not print output for files that do not have
fixed extent sizes or reservations.
-V Echo the completed command line, but do not

Operands [Toc] [Back]
getext recognizes the following operand:
file Name of file in a VxFS file system.
Notes [Toc] [Back]
Only the align and noextend allocation flags (set through setext(1M)
or the VX_SETEXT ioctl) are persistent attributes of the file and
therefore visible via getext or the VX_GETEXT ioctl. trim is also
visible, although it is cleared and the reservation is reduced on the
final close of the file.
EXAMPLES [Toc] [Back]
The following example shows a file with a block size of 1024 bytes, 36
blocks reserved, a fixed extent size of 3 blocks, and all extents
aligned to 3 block boundaries:
file1: Bsize 1024 Reserve 36 Extent Size 3 align noextend
The file size cannot be extended once the current reservation is
exhausted. Reservations and fixed extent sizes are allocated in units
of the file system block size.
