Operating Systems AIX why a directory size is different on two servers? Post 302296079 by jim mcnamara on Tuesday 10th of March 2009 10:00:36 AM

Oh.

The size of a directory file has very little to do with what is actuall in the directory.
That type of file just grows in size. If you remove some files - it stays the same size.
So as an explanation - how about at one time the 1024 size directory had more files than it does now? When copied to another box it required 512 bytes for the new directory.

NAME
shrinkfile - shrink a file on a line boundary SYNOPSIS
shrinkfile [ -n ] [ -m maxsize ] [ -s size ] [ -v ] file... DESCRIPTION
The shrinkfile program shrinks files to a given size if the size is larger than maxsize, preserving the data at the end of the file. Truncation is performed on line boundaries, where a line is a series of bytes ending with a newline, . There is no line length restriction and files may contain any binary data. Temporary files are created in the <pathtmp in inn.conf> directory. The ``TMPDIR'' environment variable may be used to specify a different directory. A newline will be added to any non-empty file that does not end with a newline. The maximum file size will not be exceeded by this addi- tion. OPTIONS
-s By default, size is assume to be zero and files are truncated to zero bytes. By default, maxsize is the same as size. If maxsize is less than size, maxsize is reset to size. The ``-s'' flag may be used to change the truncation size. Because the program trun- cates only on line boundaries, the final size may be smaller then the specified truncation size. The size and maxsize parameter may end with a ``k'', ``m'', or ``g'', indicating kilobyte (1024), megabyte (1048576) or gigabyte (1073741824) lengths. Uppercase let- ters are also allowed. The maximum file size is 2147483647 bytes. -v If the ``-v'' flag is used, then shrinkfile will print a status line if a file was shrunk. -n If the ``-n'' flag is used, then shrinkfile will exit 0 if any file is larger than maxsize and exit 1 otherwise. No files will be altered. EXAMPLES
Example usage: shrinkfile -s 4m curds shrinkfile -s 1g -v whey shrinkfile -s 500k -m 4m -v curds whey if shrinkfile -n -s 100m whey; then echo whey is way too big; fi HISTORY
