Hi Chang Min Jeon,
Please use back stick operator here, instead of system command,
because system command doesn't return anything.
Replace the system command with,
$Result = `$command`;
If ($Result) {
Print " appropriate message \n";
} else {
print " Failed message \n";
}

Regards,
Mustafa

Subject: use system() function
hello
I trying to modify file using perl one line like below.
my $cmd = "perl -pi -e's/aaa/bbb/' ";
open(MAKEFILES, '<', $ARGV[0]) or die "file open error";
my @filelist = <MAKEFILES>;
foreach my $file (@filelist) {
chomp($file);
my $command = $cmd.$file;
print $command,"\n";
!system($command) or die "shell command not work";
}
close(MAKEFILES);
but system function does not work.
It print
./Windowset/Common/Makefile.gmk
perl -pi -e's/-+g -+dwarf2//' ./Windowset/Common/Makefile.gmk
: No such file or directory.mmon/Makefile.gmk
./Windowset/Special/Makefile.gmk
perl -pi -e's/-+g -+dwarf2//' ./Windowset/Special/Makefile.gmk
: No such file or directory.cial/Makefile.gmk
