Run lynx -dump in background?
提问by system PAUSE
I have a bash script mystuffcontaining a line like
我有一个 bash 脚本，mystuff其中包含一行
lynx -dump http://example.com >tmpfile
and the script works fine, including this part, exceptwhen I run it non-interactively:
并且脚本工作正常，包括这部分，除非我以非交互方式运行它：
$ ./mystuff &
[1] 3712
$ jobs
[1]+ Stopped
The job is stopped. I find that lynx is the culprit. Even running this command directly from the bash prompt causes the job to be stopped immediately:
作业已停止。我发现lynx是罪魁祸首。即使直接从 bash 提示符运行此命令也会导致作业立即停止：
$ lynx -dump http://example.com >tmpfile &
[1] 1836
$ jobs
[1]+ Stopped
Why won't lynx run in the background? How can I fix this?
为什么lynx不会在后台运行？我怎样才能解决这个问题？
EDIT:
编辑：
I am using lynx because I don't want to have to parse the raw HTML. The difference between wgetand lynx -dumpis that lynx will render the HTML; it will hide all the tags, arrange text nicely, etc.
我使用 lynx 是因为我不想解析原始 HTML。wget和之间的区别在于lynx -dumplynx 将呈现 HTML；它将隐藏所有标签，很好地排列文本等。

Lynx wants to talk to your terminal, but can't, so it does a SIGSTP (tty input) and waits for you to foreground the process.
Lynx 想与您的终端对话，但不能，因此它执行 SIGSTP（tty 输入）并等待您将进程置于前台。
As mgb said above: use wget. wget -O tmpfile http://example.comdoes the same thing as what you're doing with lynx above.
正如mgb上面所说：使用wget。wget -O tmpfile http://example.com做与你在上面用 lynx 做的事情一样的事情。

On my system, your lynx command works as is. Try this and see what happens:
在我的系统上，您的 lynx 命令按原样运行。试试这个，看看会发生什么：
lynx -dump -term=xterm http://example.com >tmpfile &

We had luck running lynx --source http_setting://whatever|bash.
我们很幸运地运行了 lynx --source http_setting://whatever|bash。
Running as bash allowed the background process to bypass running with my personal credentials and no tty discrepancies.
以 bash 身份运行允许后台进程绕过使用我的个人凭据运行并且没有 tty 差异。
