- Xoper V1.0
-
- Copyright (c) Werner Gunther 1988
-
- Xoper is a freeware program to display and to control system activity.
- Permition is granted to freely distribute this program.
-
- --------------------------------------------------------------------------
- Changes in V1.2:
- New commands: Snoop, Capture, ClrCool, ClrWarm, ClrCold.
- Added : CPU usage by task.
-
- Cancel command has been rewritten, some minor bugs removed.
- -------------------------------------------------------------------------
-
- Starting Xoper from CLI:
-
- Xoper [T] [S] [L] [D] [R] [E] [M] [P] [I]
-
- These parameters are decribed below. For all those who like long
- Startup-Sequences, overcrowded memory and hot-keys enter
-
- Xoper -b
-
- This will install Xoper in background waiting for LeftAmiga-RightAmiga-X
- to pop up. In both cases you don't have to RUN or RUNBACK Xoper, it will
- always create its own process.
-
- Xoper Commands:
- ---------------
-
- Commands can be entered after the prompt '->', these are divided into two
- groups:
-
- Display commands: These are always single character entries and may be
- specified in any order, upper or lower case, with or w/o enbedded blanks,
- after the prompt or from CLI as parameters:
-
- T = Tasks (Default if Xoper is called without parameters)
- Task node (HEX), Display type, status, priority (decimal), CPU usage
- (percent), processnumber for Dos-Processes (decimal), taskname.
-
- S = Task Signals
- Task node (HEX), Allocated Signals (HEX), Signals the Task is waiting for
- (HEX), Signals received (HEX), Address of the next instruction to be
- executed (HEX).
-
- L = Libraries
- Base address (HEX), open count (decimal), version (decimal), revision
- (decimal), flags (binary), libraryname.
-
- D = Devices
- Base address (HEX), open count (decimal), version (decimal), revision
- (decimal), flags (binary), devicename.
-
- R = Resident
- Base address (HEX), priority (decimal), flags (binary), version
- (decimal), type, name.
-
- E = Resources (sorry)
- Base address (HEX), open count (decimal), version (decimal), revision
- (decimal), flags (binary), resource name.
-
- M = Memory
- Lower and upper bounds (HEX), bytes free (decimal), attributes, priority
- (decimal), hunk name.
-
- P = Ports
- Node address (HEX), portname, flags, signal bit (decimal), queue length
- [number of messages] (decimal), taskname.
-
- I = Interrupts
- Node address (HEX), pointer to interrupt data (HEX), pointer to interrupt
- code (HEX), priority (decimal),type [interupt queue the interrupt belongs
- to], interrupt name.
-
- H = Help ( or ?)
- Show a list of commands.
-
- Q = Quit
- Same as QUIT (see below).
-
- Example: Entering TPM would display Tasks, Ports and Memory. The display
- would be updated after a few seconds (5 by default, may be changed
- anytime, see below.)
-
- Other commands that do not display lists:
- These commands may be entered upper or lower case. Parameters enclosed
- in '<>' must be, enclosed in '[]' may be specified. Names are usualy
- entered as ascii-strings, it can however happen that two or more nodes of
- the same name exist. On tasks you may specify the DOS-Processnumber to
- sort them out. If everything fails, you can enter the Node-Address with a
- leading '$'. This Address will be checked first before the command is being
- executed. If the check fails, you'll get an error message or a warning or
- a prompt, depending on what went wrong. Names are always the last parameter
- to enter. This may seem strange, but it is the simplest way to get rid of
- enbedded blanks.
-
- Time <seconds>
- Set time between updates. Minimum is 1 second, maximum is 255, default is 5
- seconds.
- Example: Time 1
-
- Taskpri <priority> [processnumber] <taskname>
- Change the priority of a task. Values may range from -127 to 127, better
- use values between -5 and 5.
- Example: Taskpri 5 New Cli
-
- Mypri <priority>
- Shortcut for "Taskpri Xoper <priority>"
- Example: Mypri 6
-
- Pri <priority> <nodename>
- Change the priority of any other node. This commad does not work for Tasks.
- If the specified node has been found, the entire list the node belongs to
- will be resorted.
- Example: Pri 1 Chip Memory (try to allocate memory in CHIP first)
-
- Break [processnumber] <taskname>
- Set break signals. Useful for tasks running in background or from Workbench.
- Example: Break 3 New CLI
-
- Hunks [processnumber] <processname>
- Show location, BCPL-Pointers and length of memory blocks the process uses.
- Example: Hunks RAM
-
- Snoop [processnumber] <taskname>
- Track memory allocation/deallocation of a task. Press break (CTRL-C) to
- stop. List includes: action (alloc/free), memory requirents (CHIP/ FAST/
- PUBLIC etc), memory size, memory location (start, end) and the address from
- where AllocMem() was called.
-
- Files
- List lock, access, size and name of open files.
-
- Locks
- List any lock.
- BUG: Trying to lock the Volume "RAM Disk" crashes the machine sometimes. If
- a Volume "RAM Disk" is found it will be replaced by the devicename "RAM:"
- (this has been fixed on WB 1.3). Make sure you don't have a disk labeled
- "RAM Disk" or you'll never see its locks:-)
-
- Currentdir
- List current directory settings of all processes.
-
- Devices
- List name,heads,sectors,tracks,startup-buffers and handler-process of every
- DOS-device.
-
- Capture
- Show vectors controling the reset, i.e. CoolCapture, ColdCapture and
- WarmCapture pointers, KickMem allocations. Useful when searching
- for Viruses, but remember that the RAD: device in 1.3 uses the KickMem
- pointer to recover from a reset.
-
- ClrCool
- ClrCold
- ClrWarm
- Clear one of those pointers.
-
- Lockdrive <drivename:>
- Prevent DOS, Workbench and Disk-Validator from cluttering on the drive.
- This command isn't very useful, but I needed it myself. Please note that
- the drivename is case sensitive and has to end with a ':'.
-
- Freedrive <drivename:>
- Re-enable a drive.
-
- Windows
- List address and title of all windows.
-
- Screens
- List address and title of screens.
-
- Fonts
- List address,height,width,type,fist character and last character of all
- loaded fonts.
-
- Windowfonts
- List Windows and associated fonts.
-
- Freeze [processnumber] <taskname>
- Halt a Task. The task should be READY or WAITING. Frozen tasks are queued in
- a new list called FREEZED. When you leave Xoper, halted Task will be
- released.
- Example: Freeze Killer Graphics Task
-
- Warm [processnum] <taskname>
- Restart a halted Task. Task must be FREEZED.
- Example: Warm Killer Graphics Task
-
- Info <librarynode | devicenode>
- Show additional information stored in the lib_IdString field.
- Example: Info arp.library
-
- Openlib <libraryname>
- Open a library. This is useful if you don't want a specified library being
- 'flushed' out.
- Example: Openlibrary arp.library
-
- Clear [longword]
- Fill unused memory chunks with pattern, default is 0. Handy for debuggers.
- Example: Clear $66726565
-
- Flush
- Clean up memory, flush unused libraries, devices and fonts.
-
- Lastalert
- Show last Guru Meditation code or rubbish.
-
- Usage
- Toggle CPUSE field on the task display between usage relative to all
- possible dispatches and usage relative to actually dispatched tasks.
- Ahem...not very clear I think. Well, let me try again...
- If you add all CPUSE fields together you get 100 % (more or less 1%). After
- entering "Usage" adding the fields together will give you the same value as
- shown in the 'CPU Activity field'. (I HATE having to write docs)
-
- Taskports
- Disable / enable a listing of taskports if ports are displayed.
-
- More
- Stop displaying "<MORE>" and "<RETURN>" if output exceeds window.
-
- Quit or just Q
- Exit Xoper. If Xoper was started with '-b' or if 'Hold' was specified it
- will stay in background waiting for LeftAmiga-RightAmiga-X.
-
- Hold
- Exit Xoper but install a key-handler and stay in background. Window
- settings and display commands are saved.
-
- Exit
- Clean up and quit.
-
- !!!! WARNING: The next few commands are dangerous and 'dirty' !!!!!
- !!!!!!!!!!!! don't use them if not strictly necessary !!!!!!!!!!!!!
-
- Cancel [processnumber] <taskname>
- Cancel a task or a process. If the task has been called from CLI, the Task
- itself and the CLI will be killed. Hunks, Windows, Screens and the
- teminal-window will be freed. Simple tasks are just RemTask()'ed. If it is
- not a CLI Task you'll be asked if it is a Workbench task, if the answer is
- 'Yes' unloading will be done by the Workbench. If not, you will be prompted
- if Xoper should unload the code. Enter 'No' if you don't know how the task
- has been started.
-
- Closewindow <title>
- Closes a Window. Please, use it only if the corresponding Task has been
- 'Cancel'ed. Use the Window-Structure address if the window has no name.
-
- Closescreen <title>
- same as above, but for screens.
-
- Unlock <lock (BPTR)>
- Unlock a file.
-
- Closelib <libraryname>
- This is exactly the same as CloseLibrary().
-
- CD [processnumber] <processname>
- Change the current directory of a process. You are prompted if the old
- directory lock should be unlocked.
-
- Signal <mask> [processnumber] <taskname>
- Set any task-signal. Mask is a hexadecimal value with or w/o leading '$'.
- See task's SIGWAIT field for sensible values. Tasks normaly do not wait for
- signals only, but for messages, that's why this command may not have the
- desired effect, but it is quite useful for tasks hanging around and waiting
- for events that may never happen. Warning: Using Signal without any
- knowledge about what you are going to signal may cause a system-crash!
- Example: Signal 10000000 PopCLI III
