hello, i have a segment of code as followed:
...
#path for rlog command
$CMD{rlog} = 'D:/project/programs/rcs';
if (defined($tag)) {
if (!open($fh, "-|")) { #TRUE
open(STDERR, '>/dev/null') ;
# execute rlog comand for a list of the files
exec($CMD{rlog}, @files) or exit -1;
}
} else {
.....
}
I found that the code after this segment can not be executed at all. even a print operation can get nothing displyed. I don't know why. Seems the current task executed by this segment can not exit so that the program can not continue. but i indeed put "exit" there.
what is wrong with code?
pls help! thanks alot
