- 1. INTRODUCTION
-
- What exactly is Usage? Usage is basicly the du (disk usage) command
- from UNIX. The only difference is, that this program has more
- options, mainly the availability to make comparisons and return WARN
- if the given amount is exceeded. And, of course wildcards, too. Now
- you can check out for example the amount of .info's on your precious
- hard disk (I've got over 600 KBs on my boot partition only)...
-
- This program was coded because we will need a command like this
- in the future when we install MuFS to the Amiga 4000 at the Oulu
- University. Each user will have a home-directory of their own,
- and we need to limit that size and warn the user if the preferred
- disk usage is exceeded.
-
- Also, the previous DU command that I had wasn't hit-free, it
- produced some Enforcer hits when executed. I don't like Enforcer
- hits, so that gave me some more motivation to do this program.
-

-
- 2. COPYRIGHT & DISCLAIMER
-
- This program is copyrighted, but FREELY DISTRIBUTABLE. If you use
- it and like it, a donation or gift would be nice; a postcard,
- intros, demos, public domain software, money etc. I'm a student,
- and money simply doesn't want to live with me... ;(
-
- Selling this program for more than reasonable media cost is strictly
- forbidden. A special permit is given to Fred Fish so that he can
- include this program to his CD-ROMs. Also, this program may be
- copied to the AmiNet CD-ROM. Others may require this permit from
- me, contact address is in the CONTACT THE AUTHOR part of this
- document.
-
- Add all standard disclaimers here, I'm in no way responsible
- of what this program might cause to you; may it be data corruption,
- number of aliens visiting your house, mental or physical health
- problems. This program has been thoroughly tested and it should
- not cause any problems, but who am I to promise anything? Big
- companies can't keep their promises either - Microsoft 100%
- guarantee of bugged & bloated software.
-
- -----------------------------------------------------------------------------
-
- 3. INSTALLACTION & USAGE
-
- Quite simple, just copy the program USAGE to the directory
- you wish it should be in, just make sure your PATH points to
- that directory. Please refer to the manuals of your computer
- on the COPY and PATH-command.
-
- Usage [OPTIONS] [PATH] [OPTIONS]
-
- Path is the path/volume of which you want to know the disk usage.
- Only one parameters has to be given, it may be the path or any
- of the options. If a path is not given, the current directory
- will be scanned.
-
- ALL - recursive, calculate the size of all sub-directories too
- QUIET - no output at all, expect errors
- SHORT - print only the first level of directories
- VERBOSE - print the directories and their sizes
- LEVEL - print only the given amount of directory levels
- COMPARE - compare the disk usage to a given amount, which MUST
- follow immediately after the COMPARE keyword.
- NOADD - as of version 1.04 the default output form has been
- been changed, use this option for the previous output.
- By default the size of a parent directory is calculated
- not only from the files within that directory but it's
- subdirectories, too (just like the du in UNIX).
- FILELIST - create a filelist of files used for disk usage calculation.
- The option LEVEL does not affect the file creation.
-
-
- Options may be given in upper or lower case, the checking is not
- case sensitive. And, they may be given in any order as well.
-
- Some examples might clear things out;
-
- USAGE
- - no parameters, short instructions displayed
-
- USAGE RAM:
- - calculate the disk usage of RAM:
-
- USAGE ALL
- USAGE -A
- - calculate the disk usage of the current directory and all of its
- subdirectories, too.
-
- USAGE RAM: ALL
- USAGE RAM: -A
- - calculate the TOTAL disk usage of RAM:
-
- USAGE RAM:*.info ALL
- - calculate the TOTAL amount of .info-files on RAM:
-
- USAGE RAM: ALL QUIET
- - calculate the TOTAL disk usage on RAM: do not produce any output
- (except possible memory allocation errors etc!)
-
- USAGE RAM: ALL SHORT
- USAGE RAM: ALL LEVEL 1
- USAGE RAM: -A -L 1
- - calculate the TOTAL disk usage on RAM: and display the amount of
- disk space used in the first directory levels.
-
- USAGE RAM: ALL VERBOSE
- USAGE RAM: -A -V
- - calculate the TOTAL disk usage on RAM: and display the amounts as
- the program preceeds in the directory tree. Like the DU command in
- UNIX.
-
- USAGE RAM: ALL VERBOSE FILELIST TEMP:files
- USAGE -A -V -F TEMP:files RAM:
- - calculate the TOTAL disk usage of RAM: and display the amounts
- as the program preceeds in the directory tree. Saves the filenames
- used for disk usage calculation to TEMP:files.
-
- USAGE RAM: ALL COMPARE 100
- USAGE RAM: ALL COMP 100
- USAGE RAM: -A -C 100
- - calculate the TOTAL disk usage on RAM: and compare the amount to
- 100 KILOBYTES and return WARN if the amount is exceeded.
-
- USAGE RAM: ALL COMP 100 VERBOSE
- USAGE RAM: -A -C 100 -V
- - same as above, but also displays the size of each directory as
- the program works its way through the directory tree.
-
- And all of the other variations you can imagine. You can't use
- the keywords QUIET, VERBOSE and SHORT on the same command line!
-
- If you want to have that traditional DU-command familiar from
- UNIX (and Amiga-ports) define an alias like this in your S:SHELL-STARTUP
-
- ALIAS DU USAGE ALL VERBOSE
-
- or, any other way you prefer it.
-
- See the file HomeFull.script in this archive for an example of
- how to use the COMPARE-option in a script.

- 4. BUGS
-
- There aren't any bugs I know of at this point. But, there are
- a few things you should remember. This program is recursive,
- the sub-directory scanning is done with recursion. Recursion
- uses the stack. Each recursion level uses stack about 100 bytes.
- The program currently allocates a stack of 10240 bytes IF you
- use a smaller stack. That amount is enough for about 80 directory
- levels, but if you have VERY complex directory structures please
- use the STACK command to increase the stack size before running
- this program with the ALL-switch.
-
- Please do notice, that using CTRL-C to abort the program while
- it is scanning a directory will cause memory loss. The program
- is recursive, and the temporary path names allocated by each
- recursion level are lost.
-
- But, if you do happend to find a bug or two, please inform me
- immediately and I will try to fix them. Or, if you have any
- nice improvement ideas. My address is in the CONTACT THE AUTHOR-
- part of this documentation.

-
- 5. NOTES
-
- This program was compiled using the SAS/C Development System
- version 6.51 and tested with Enforcer and Mungwall; hit free
- program.
-
- This program needs at least dos.library version 37, ie.
- KICKSTART 2.0 is required! Go and get an upgrade if you're
- still using 1.2 or 1.3. Or even better, go get yourself
- an Amiga 1200 or 4000...

- 7. HISTORY
-
- VERSION 1.06 (21.3.1994)
-
- - new option, FILELIST. Creates a list of all the files used for
- the disk usage.
-
- - added a new option, LEVEL. It defines the number of directory
- levels to be printer when scanning the directory tree. It does
- NOT define the level of directories to scan through!
-
- - cleaned up the source quite a bit.
-
- - changed the way usage prints out the size of directories, now (by
- default) the size of parent directory is the size of all the files
- in that directory, including subdirectories. You can avoid this
- behaviour by using the new switch NOADD.
- Enhancement requested by Jack Nutting.
-
- - modified the argument handling, it's much more flexible now.
- You can give the arguments in any order now, even the path may
- be anywhere in the command line - now it's much easier to "make"
- a DU command of your own with aliases.
-
- VERSION 1.02 (14.3.1994)
-
- - a small enhancement, added the option SHORT.
- Enhancement requested by Rob Hardy.
-
- VERSION 1.01 (7.3.1994)
-
- - a small bugfix, didn't handle assigns correctly. For example
- USAGE DATA: ALL scanned the whole device where DATA: was located.
- Bug reported by Rob Hardy.
-
- VERSION 1.0 (19.2.1994)
-
- - first public release
-
