Why don't you just

<pre><code>GENERATE INPUT | (
 # do whatever you like to the input here
)
</code></pre>

But sometimes, especially when you want to complete the input first, then operate on the modified output, you should still use temporary files:

<pre><code>TMPFILE="/tmp/fileA-$$"
GENERATE INPUT | (
 # modify input
) &gt; "$TMPFILE"
(
 # do something with the input from TMPFILE
) &lt; "$TMPFILE"
rm "$TMPFILE"
</code></pre>

blocks|key|919718|text|我不认为有从stdin到EOF的内置内容，但您可以这样做：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|919719|#!/bin/bash
exec+>+/tmp/file
while+IFS=+read+-r+line;+do
++printf+'%25s\n'+"$line"

I don't think there is a builtin that reads from stdin until EOF, but you can do this:

<pre><code>#!/bin/bash
exec &gt; /tmp/file
while IFS= read -r line; do
 printf '%s\n' "$line"
done
</code></pre>

blocks|key|1690928|text|另一种使用纯BASH的方法：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1690929|#!/bin/bash

IFS=+read+-t+0.01+-r+-d+''+indata

[[+-n+$indata+]]+&&+printf+"%25s"+"$indata"+>/tmp/file|code-block|syntax|javascript|1690930|IFS=和-d+''导致将所有stdin数据读入变量indata中。|offset|length|style|CODE|1690931|在没有输入管道的情况下调用此脚本时，使用-t+0.01**:**的原因，则read将在可忽略的0.01秒延迟后超时。如果输入中有可用的数据，则将在indata变量中读取数据，并将其重定向到>/tmp/file。|BOLD|1690932|entityMap^0|0|0|0|4|5|5|Q|6|0|K|9|X|20|K|7|11|4|1B|4|21|6|2M|A|0^^$0|@$1|2|3|4|5|6|7|R|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|S|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|T|8|@$I|U|J|V|K|L]|$I|W|J|X|K|L]|$I|Y|J|Z|K|L]]|9|@]|A|$]]|$1|M|3|N|5|6|7|10|8|@$I|11|J|12|K|O]|$I|13|J|14|K|O]|$I|15|J|16|K|L]|$I|17|J|18|K|L]|$I|19|J|1A|K|L]|$I|1B|J|1C|K|L]|$I|1D|J|1E|K|L]]|9|@]|A|$]]|$1|P|3|-4|5|6|7|1F|8|@]|9|@]|A|$]]]|Q|$]]

Another way of doing it using pure BASH:

<pre><code>#!/bin/bash

IFS= read -t 0.01 -r -d '' indata

[[ -n $indata ]] &amp;&amp; printf "%s" "$indata" &gt;/tmp/file
</code></pre>

<code>IFS=</code> and <code>-d ''</code> causes all of stdin data to be read into a variable <code>indata</code>.

Reason of using <code>-t 0.01</code>: When this script is called with no input pipe then <code>read</code> will timeout after negligible <code>0.01</code> seconds delay. If there is any data available in input it will be read in <code>indata</code> variable and it will be redirected to <code>&gt;/tmp/file</code>.

blocks|key|158392|text|你可以简单地|type|unstyled|depth|inlineStyleRanges|entityRanges|data|158393|cp+/dev/stdin++myfile.txt|code-block|syntax|javascript|158394|终止您的输入与Ctrl%2BD或Ctrl%2BZ和，中提琴！您可以使用stdin中的文本创建文件。|158395|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

You could simply do 

<pre><code>cp /dev/stdin myfile.txt
</code></pre>

Terminate your input with Ctrl+D or Ctrl+Z and, viola! You have your file created with text from the stdin.

blocks|key|1690987|text|另一种选择：dd+of=/tmp/myfile/txt|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1690988|注意：--这是而不是--内置的，但是，它可能会帮助其他人寻找一个简单的解决方案。|BOLD|1690989|entityMap^0|6|L|0|0|3|7|3|0^^$0|@$1|2|3|4|5|6|7|K|8|@$9|L|A|M|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|N|8|@$9|O|A|P|B|H]|$9|Q|A|R|B|H]]|D|@]|E|$]]|$1|I|3|-4|5|6|7|S|8|@]|D|@]|E|$]]]|J|$]]

Another option: <code>dd of=/tmp/myfile/txt</code>

Note: This is not a built-in, however, it might help other people looking for a simple solution.

blocks|key|919929|text|如果您不希望程序在到达EOF后结束，这可能会有所帮助。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|919930|#!/bin/bash
exec+<+<(tail+-F+/tmp/a)
cat+-|code-block|syntax|javascript|919931|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

If you don't want the program to end after reaching EOF, this might be helpful.
<pre><code>#!/bin/bash
exec &lt; &lt;(tail -F /tmp/a)
cat -
</code></pre>

Consider this very simple bash script:

<pre><code>#!/bin/bash
cat &gt; /tmp/file
</code></pre>

It redirects whatever you pipe into it to a file. e.g.

<pre><code>echo "hello" | script.sh
</code></pre>

and "hello" will be in the file /tmp/file. This works... but it seems like there should be a native bash way of doing this without using "cat". But I can't figure it out.

NOTE: 

<ol>
<li>It must be in a script. I want the script to operate on the file contents afterwards. </li>
<li>It must be in a file, the steps afterward in my case involve a tool that only reads from a file.</li>
<li>I already have a pretty good way of doing this - its just that it seems like a hack. Is there a native way? Like "/tmp/file &lt; 0 " or "0> /tmp/file". I thought bash would have a native syntax to do this...</li>
</ol>

考虑下面这个非常简单的bash脚本：#!/bin/bashcat > /tmp/file它会将你的管道重定向到一个文件中。例如：echo "hello" | script.sh"hello“将出现在文件/tmp/file中。这很管用..。但似乎应该有一种不使用"cat“的本地bash方式来实现这一目的。但我搞不懂。注意...
