!!! comparing SIZES !!!
Hello sir,
I did understand that they are only for object files.
My target was to compare txt files and their corresponding .gz,.z files to show the difference in the size.
I used :-
But still I am not able to see the difference in blocks.When I did "ls -l" I DISCOVERED that .z,.gz are larger that the .txt file.Can you tell me how to compress them?

xfs_rtcp
xfs_rtcp(8) System Manager's Manual xfs_rtcp(8)
NAME
xfs_rtcp - XFS realtime copy command
SYNOPSIS
xfs_rtcp [ -e extsize ] [ -p ] source ... target
DESCRIPTION
xfs_rtcp copies a file to the realtime partition on an XFS filesystem. If there is more than one source and target, the final argument
(the target) must be a directory which already exists.
OPTIONS
-e extsize
Sets the extent size of the destination realtime file.
-p Use if the size of the source file is not an even multiple of the block size of the destination filesystem. When -p is specified
xfs_rtcp will pad the destination file to a size which is an even multiple of the filesystem block size. This is necessary since
the realtime file is created using direct I/O and the minimum I/O is the filesystem block size.
SEE ALSO
xfs(5), mkfs.xfs(8), mount(8).
CAVEATS
Currently, realtime partitions are not supported under the Linux version of XFS, and use of a realtime partition WILL CAUSE CORRUPTION on
the data partition. As such, this command is made available for curious DEVELOPERS ONLY at this point in time.
