Top Forums Shell Programming and Scripting error "test: [-d: unary operator expected" very confused. Post 302325278 by ahmad.diab on Sunday 14th of June 2009 09:49:30 AM

You have to remove the word "test", the if statment is enough..

example:-

if [ -d TEMP ]
then
echo "it is a directory"
else
mkdir TEMP
fi

and it will work..

NAME
extract_font_range - Extracts a range of characters from a font. Allegro game programming library. SYNOPSIS
#include <allegro.h> FONT *extract_font_range(FONT *f, int begin, int end) DESCRIPTION
This function extracts a character range from a font and returns a new font that contains only the range of characters selected by this function. You can pass -1 for either the lower or upper bound if you want to select all characters from the start or to the end of the font. Example: FONT *myfont; FONT *capitals; FONT *fontcopy; ... /* Create a font of only capital letters */ capitals = extract_font_range(myfont, 'A', 'Z'); /* Create a copy of the font */ fontcopy = extract_font_range(myfont, -1, -1); ... destroy_font(capitals); destroy_font(fontcopy); RETURN VALUE
Returns a pointer to the new font or NULL on error. Remember that you are responsible for destroying the font when you are finished with it to avoid memory leaks. SEE ALSO
