#133 DirSize
Directory Size Scanner for OS/2 v2.0 written in REXX
Notes
NB: this was written (and last tested!) in 1993
System Requirements
DirSize requires REXX to be properly installed on your system. It also requires RXQUEUE.EXE which should be found in C:\OS2. It has been developed under IBM OS/2 v2.0 - I’m not sure how it will go under previous versions.
About DirSize
DirSize started off as a simple utility to find out who the hell was using up the space on our file server. It still is a simple utility! All it does is list directories/sub-directories and tell you how much space each consumes. It is possible to get the list sorted by size, and also to prevent the reporting of directories that do not meet a “minimum size” for reporting.
Note that the DIR command can give you all the size details that DirSize reports. DirSize simply reports the info better.
Using DirSize
Getting help: DIRSIZE /?
Usage:
DIRSIZE [filespec] [dir options] [/D] [/Mxxx]
Output is generally a list with each line having the form:
<full directory path><tab><size used><space>"bytes"
Use the standard options you would use with the DIR command to tell DIRSIZE where and what to scan. For example, to scan all of C:\OS2PROJ\REXX use
Example:
DIRSIZE C:\os2proj\rexx
DirSize v1.0 (c) Paul Gallagher 1993 {paulg@a1.resmel.bhp.com.au}
C:\os2proj\rexx 45815 bytes
C:\os2proj\rexx\chat 15518 bytes
C:\os2proj\rexx\db2inf 10721 bytes
C:\os2proj\rexx\db2inf\test 193466 bytes
C:\os2proj\rexx\rps 235995 bytes
C:\os2proj\rexx\VArc 37497 bytes
Size of directory tree: 539012 bytes
Note that DirSize always scans and reports on subdirectories under the directory specified. If you just want to know how much space the directory c:\os2 uses, then shit, use DIR! Although you can use all of the parameters permitted by DIR, many don’t make sense when using DirSize (such as /O, /L or /S).
The /D parameter requests DirSize to order the directories in order of space used. By default, most hungry dirs are shown first!
Example:
DIRSIZE C:\os2proj\rexx /D
DirSize v1.0 (c) Paul Gallagher 1993 {paulg@a1.resmel.bhp.com.au}
C:\os2proj\rexx\rps 235995 bytes
C:\os2proj\rexx\db2inf\test 193466 bytes
C:\os2proj\rexx 45815 bytes
C:\os2proj\rexx\VArc 37497 bytes
C:\os2proj\rexx\chat 15518 bytes
C:\os2proj\rexx\db2inf 10721 bytes
Size of directory tree: 539012 bytes
The /M parameter is used to mask the output listing based upon space used. For a parameter /Mxxx, only directories using more than ‘xxx’ bytes are displayed. However, all directories regardless of size are still scanned - only the report is affected. The /M paramter must appear last on the command line. The /M can appear with or without the /D parameter.
Example:
DIRSIZE C:\os2proj\rexx /D /M40000
DirSize v1.0 (c) Paul Gallagher 1993 {paulg@a1.resmel.bhp.com.au}
C:\os2proj\rexx\rps 235995 bytes
C:\os2proj\rexx\db2inf\test 193466 bytes
C:\os2proj\rexx 45815 bytes
Size of listed directories: 475276 bytes
Size of directory tree: 539012 bytes
