File change detection

[Bangieff]

Hi all
Can anyone tell me how may I untherstand immediatly when a file has been changed without looping?

thanks

 

[Lim]

check the date

 

[sramki]

use the stat command .

stat <filename>

u can use the ctime(member of stat ) to see whether the file has changed or not

regards
sramki

What I meaned was without looping...
If I use some of these methods I shoud do something like

while(1)
{
lstat(&quot;file.dat&quot;,filestat);
....
}

but I want to avoid this &quot;while&quot; loop....
