set_clip_rect(3alleg4) Allegro manual set_clip_rect(3alleg4)NAME
set_clip_rect - Sets the clipping rectangle of a bitmap. Allegro game programming library.
void set_clip_rect(BITMAP *bitmap, int x1, int y1, int x2, int y2);
Each bitmap has an associated clipping rectangle, which is the area of the image that it is OK to draw onto. Nothing will be drawn to posi-
tions outside this space. This function sets the clipping rectangle for the specified bitmap. Pass the coordinates of the top-left and bot-
tom-right corners of the clipping rectangle in this order; these are both inclusive, i.e. set_clip_rect(bitmap, 16, 16, 32, 32) will allow
drawing to (16, 16) and (32, 32), but not to (15, 15) and (33, 33).
Drawing operations will be performed (at least partially) on the bitmap as long as the first coordinates of its clipping rectangle are not
greater than the second coordinates and its intersection with the actual image is non-empty. If either condition is not fulfilled, drawing
will be turned off for the bitmap, e.g.
set_clip_rect(bmp, 0, 0, -1, -1); /* disable drawing on bmp */
Note that passing "out-of-bitmap" coordinates is allowed, but they are likely to be altered (and so the coordinates returned by
get_clip_rect() will be different). However, such modifications are guaranteed to preserve the external effect of the clipping rectangle,
that is not to modify the actual area of the image that it is OK to draw onto.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it

I'm trying to delete a file with a weird name from within Terminal on a Mac.
It's a very old file (1992) with null characters in the name: ââWord FinderÂŽ Plusâ˘.
Here are some examples of what I've tried:
12FX009:5 dpontius$ ls
