Good morning!
I met a problem on a FS with AIX 5.3
It's not possible to mount the FS because of a dirty superblock.
I tried few things without success. I need your help to solve my problem guys. Do you have any idea please?
I am creating a small bash file that will take one argument and compile it:
#!/bin/bash
OUT=${$1%.cpp} # C++ source files always end in .cpp
g++ -Wall $1 -o $OUT
chmod 777 $OUT The error message says 'bad substitution', namely where OUT is defined. How to fix this? (1 Reply)

Hello,
After a replacement of the motherboard of my server, all disks belonging to a raid6 are now marked as spare.
Is there any way to mark those disks as active and restore the raid6?

I have a list of multiple versions of software. The list is formated as follows:
NAME VERSION
I simply need to pull out the highest version of each software, for example:
Original File
a v1.0
a v1.1
a v1.2
b v2.1
b v2.2
b v2.21

Hi All,
How worried is everyone about the Dirty Cow Linux exploit? Has anybody experienced attacks yet?
From the research I've done it seems that the exploit is "reliable" (that is it works nearly every time on vulverable systems) which is not good news.
We all believe that Unix/Linux... (3 Replies)

Functions
__extern int caca_disable_dirty_rect (caca_canvas_t *)
Disable dirty rectangles.
__extern int caca_enable_dirty_rect (caca_canvas_t *)
Enable dirty rectangles.
__extern int caca_get_dirty_rect_count (caca_canvas_t *)
Get the number of dirty rectangles in the canvas.
__extern int caca_get_dirty_rect (caca_canvas_t *, int, int *, int *, int *, int *)
Get a canvas's dirty rectangle.
__extern int caca_add_dirty_rect (caca_canvas_t *, int, int, int, int)
Add an area to the canvas's dirty rectangle list.
__extern int caca_remove_dirty_rect (caca_canvas_t *, int, int, int, int)
Remove an area from the dirty rectangle list.
__extern int caca_clear_dirty_rect_list (caca_canvas_t *)
Clear a canvas's dirty rectangle list.
Detailed Description
These functions manipulate dirty rectangles for optimised blitting.
Function Documentation
__extern int caca_disable_dirty_rect (caca_canvas_t *cv) Disable dirty rectangle handling for all libcaca graphic calls. This is handy when the
calling application needs to do slow operations within a known area. Just call caca_add_dirty_rect() afterwards.
This function is recursive. Dirty rectangles are only reenabled when caca_enable_dirty_rect() is called as many times.
This function never fails.
Parameters:
cv A libcaca canvas.
Returns:
This function always returns 0.
__extern int caca_enable_dirty_rect (caca_canvas_t *cv) This function can only be called after caca_disable_dirty_rect() was called.
If an error occurs, -1 is returned and errno is set accordingly:
o EINVAL Dirty rectangles were not disabled.
Parameters:
cv A libcaca canvas.
Returns:
0 in case of success, -1 if an error occurred.
__extern int caca_get_dirty_rect_count (caca_canvas_t *cv) Get the number of dirty rectangles in a canvas. Dirty rectangles are areas that
contain cells that have changed since the last reset.
The dirty rectangles are used internally by display drivers to optimise rendering by avoiding to redraw the whole screen. Once the display
driver has rendered the canvas, it resets the dirty rectangle list.
Dirty rectangles are guaranteed not to overlap.
This function never fails.
Parameters:
cv A libcaca canvas.
Returns:
The number of dirty rectangles in the given canvas.
__extern int caca_get_dirty_rect (caca_canvas_t *cv, intr, int *x, int *y, int *width, int *height) Get the canvas's given dirty rectangle
coordinates. The index must be within the dirty rectangle count. See caca_get_dirty_rect_count() for how to compute this count.
If an error occurs, no coordinates are written in the pointer arguments, -1 is returned and errno is set accordingly:
o EINVAL Specified rectangle index is out of bounds.
Parameters:
cv A libcaca canvas.
r The requested rectangle index.
x A pointer to an integer where the leftmost edge of the dirty rectangle will be stored.
y A pointer to an integer where the topmost edge of the dirty rectangle will be stored.
width A pointer to an integer where the width of the dirty rectangle will be stored.
height A pointer to an integer where the height of the dirty rectangle will be stored.
Returns:
0 in case of success, -1 if an error occurred.
__extern int caca_add_dirty_rect (caca_canvas_t *cv, intx, inty, intwidth, intheight) Add an invalidating zone to the canvas's dirty rectangle
list. For more information about the dirty rectangles, see caca_get_dirty_rect().
This function may be useful to force refresh of a given zone of the canvas even if the dirty rectangle tracking indicates that it is
unchanged. This may happen if the canvas contents were somewhat directly modified.
If an error occurs, -1 is returned and errno is set accordingly:
o EINVAL Specified rectangle coordinates are out of bounds.
Parameters:
cv A libcaca canvas.
x The leftmost edge of the additional dirty rectangle.
y The topmost edge of the additional dirty rectangle.
width The width of the additional dirty rectangle.
height The height of the additional dirty rectangle.
Returns:
0 in case of success, -1 if an error occurred.

__extern int caca_remove_dirty_rect (caca_canvas_t *cv, intx, inty, intwidth, intheight) Mark a cell area in the canvas as not dirty. For more
information about the dirty rectangles, see caca_get_dirty_rect().
Values such that xmin > xmax or ymin > ymax indicate that the dirty rectangle is empty. They will be silently ignored.
If an error occurs, -1 is returned and errno is set accordingly:
o EINVAL Specified rectangle coordinates are out of bounds.
Parameters:
cv A libcaca canvas.
x The leftmost edge of the clean rectangle.
y The topmost edge of the clean rectangle.
width The width of the clean rectangle.
height The height of the clean rectangle.
Returns:
0 in case of success, -1 if an error occurred.
__extern int caca_clear_dirty_rect_list (caca_canvas_t *cv) Empty the canvas's dirty rectangle list.
This function never fails.
Parameters:
cv A libcaca canvas.
Returns:
This function always returns 0.
