问题描述

我执行了以下命令(源):

I did the commands (source):

$ exec 3>/tmp/thirdfile
$ exec 4>/tmp/fourthfile
$ echo drib >&3
$ echo drab >&4
$ echo another drib >&3

如何查看文件句柄(类似于lsof -l)?

How can I see the file handles, something like with lsof -l?

推荐答案

我不明白，为什么不只使用lsof:

I don't understand, why not just use lsof:

lsof -p $$

$$是一个shell变量，用于保存shell的进程ID

$$ being a shell variable that holds the shell's process ID

您还可以将文件描述符限制为:

You can also limit to just file descriptors like:

lsof -a -d0-65535 -p $$
