导读：open(FP,$file) || die "cannot open file $!"; binmode(FP); open(TMPFP,"a.tmp" || die "cannot open file $!"; binmode(TMPFP); my $buffer = ""; while(read(FP,$buffer,1024)) { ? syswrite(TMPFP,length($buffer)); ? print "$buffer"; ? print '=' x

open(FP,$file) || die "cannot open file $!"; binmode(FP);
open(TMPFP,">a.tmp"|| die "cannot open file $!"; binmode(TMPFP);
my $buffer = "";
while(read(FP,$buffer,1024)) { ? syswrite(TMPFP,length($buffer)); ? print "$buffer"; ? print '=' x 24; } close(FP); close(TMPFP);
