[英]linux stdout pipe issues
I have a server program just writes output log to STDOUT. 我有一个服务器程序只是将输出日志写入STDOUT。 I also have another Perl shell script named "logfile" ,it will gets data from STDIN and shows some output.
我还有另一个名为“logfile”的Perl shell脚本,它将从STDIN获取数据并显示一些输出。
linux$ server | logfile
at first log-file has output ,but after a few moments it stops.. is there anyone has came across this problem? 在第一个日志文件有输出,但过了一会儿它停止..有没有人遇到过这个问题?
server
probably buffers its output, feeding it to the pipe in chunks. server
可能会缓冲其输出,将其以块的形式提供给管道。 Is server
a Perl script? server
是Perl脚本吗? Add 加
$| = 1;
or 要么
use Handle qw( );
STDOUT->autoflush(1);
to it to disable buffering for STDOUT. 它禁用STDOUT的缓冲。 (Well, the first one will disable buffering for whatever handle you have
select
ed, but that's STDOUT by default.) (好吧,第一个会为你
select
任何句柄禁用缓冲,但默认情况下这是STDOUT。)
