在替换之前通过外部程序管道 sed 捕获组？
Pipe sed capture group through external program before replacing?
有没有办法 sed 将捕获组通过管道传递给另一个程序，使正则表达式的 RHS 中的 </code> 等于该程序的输出？</p>
<p>例如，运行</p>
<pre><code>sed 's/lorem ipsum \(foobar\)//g' file.txt
会通过另一个程序（例如 tr 'o' 'a'）将 "foobar" 管道化，使 </code> 成为 "faabar"，让 <code>sed 替换 "lorem ipsum foobar" "lorem ipsum faabar"?
这只是一个简单的例子。我意识到我可以在不使用 tr.
的情况下将 "foobar" 转换为 "faabar"
使用执行选项：
e
This command allows one to pipe input from a shell command into pattern space. If a substitution was made, the command that is found in pattern space is executed and pattern space is replaced with its output. A trailing newline is suppressed; results are undefined if the command to be executed contains a NUL character. This is a GNU sed extension.
