Thanks for the reply,
Code:
 
 
filefound=0
 
while [[ $filefound -eq 0 ]]
do
 
if [[ -f abc.dat ]]
then
mv abc.dat xyz.dat
filefound=1
fi
 
done

In the above if the file is not found the loop keeps iterating, adding a sleep command will introduce some wait between iterations. Just wondering if by adding the sleep will add any advantage in terms reducing processor load OR it just doesn't make any difference.

Thanks
Zulfi

load_datafile(3alleg4)						  Allegro manual					    load_datafile(3alleg4)

NAME
load_datafile - Loads a datafile into memory. Allegro game programming library. SYNOPSIS
#include <allegro.h> DATAFILE *load_datafile(const char *filename); DESCRIPTION
Loads a datafile into memory in one go. If the datafile has been encrypted, you must first call packfile_password() to set the appropriate key. If the datafile contains truecolor graphics, you must set the video mode or call set_color_conversion() before loading it. Example: /* Load the resources for our game. */ DATAFILE *dat = load_datafile("game.dat"); if (!dat) abort_on_error("Couldn't load sound resources!"); /* Use resources. */ ... /* Destroy them when we don't need them any more. */ unload_datafile(dat); RETURN VALUE
Returns a pointer to the DATAFILE, or NULL on error. Remember to free this DATAFILE later to avoid memory leaks. SEE ALSO
