@Scrutinizer: can you please explain what is "IFS" in this loop.is it the string that I'm trying to search? and why i need text.out? can't i go without it? and sorry If my question wasn't clear enough.

simply, I just need a way to keep a check all the time on a log file so that whenever some specific text comes into that file, i get alert regarding that text. any function call? or any loop, condition? any way in scripting?

Thanks for your time and efforts.

alert(3alleg4)                                                    Allegro manual                                                    alert(3alleg4)

NAME
alert - Displays a popup alert box. Allegro game programming library. SYNOPSIS
#include <allegro.h> int alert(const char *s1, *s2, *s3, const char *b1, *b2, int c1, c2); DESCRIPTION
Displays a popup alert box, containing three lines of text (s1-s3), and with either one or two buttons. The text for these buttons is passed in `b1' and `b2' (`b2' may be NULL), and the keyboard shortcuts in `c1' and `c2' as ASCII value. Example: if (!exists(CONFIG_FILE)) alert(CONFIG_FILE, "not found.", "Using defaults.", "&Continue", NULL, 'c', 0); RETURN VALUE
Returns 1 or 2 depending on which button was clicked. If the alert is dismissed by pressing ESC when ESC is not one of the keyboard short- cuts, it treats it as a click on the second button (this is consistent with the common "Ok", "Cancel" alert). SEE ALSO
