当你向某个过程投管时,管道与这一进程相连,是标准投入。 这意味着你们的终端投入与编辑连接起来。 多数编辑还检查其标准投入是否为终端(isatty, 管道为t;如果是个终点站,他们就拒绝开办。 在<代码>nano的情况下,这似乎使其偏离了你包括的信息:

% echo | nano
Received SIGHUP or SIGTERM

如果你希望能向设在终端的编辑传递其标准投入,那么你就不得不以另一种方式,如通过档案,向您的陈词提供意见。

现在,你澄清了你的问题,即你不希望打捞过程stdin。 附录一

editorprocess = subprocess.Popen([editor or "vi", temppath],
                                 stdin=open( /dev/tty ,  r ))

此处处理<代码>find -type f vidir-具体案例:

foreach my $item (@ARGV) {
    if ($item eq "-") {
        push @dir, map { chomp; $_ } <STDIN>;
        close STDIN;
        open(STDIN, "/dev/tty") || die "reopen: $!
";
    }

你们也可以在沙尔恢复这一行为:

#!/usr/bin/python

import os
import sys

sys.stdin.close()
o = os.open("/dev/tty", os.O_RDONLY)
os.dup2(o, 0)
os.system( vim )

当然,closes 标准输入档案记录员,因此,如果您在编辑开始后打算再次阅读,你可能会在结案前重复其档案记录。
