Linux append console output to a logfile?
提问by Wingblade
I know that I can let Linux to write the console output to a logfile by doing:
我知道我可以通过执行以下操作让 Linux 将控制台输出写入日志文件：
command > logfile.log
But this overwrites whatever was in the logfile before. How do I make it append the output to the logfile rather than overwriting it?
但这会覆盖之前日志文件中的任何内容。如何让它将输出附加到日志文件而不是覆盖它？

A couple ways:
几种方式：
1) Uses io piping as follows:
1）使用io管道如下：
$> echo 'some text' >> file.txt (will be appended)
$> echo 'some text' >> file.txt（将被附加）
2) Using a program like sed:
2）使用像sed这样的程序：
$> cat file.txt
$> 猫文件.txt
some text
一些文字
$> sed -i '$ a\ here is some more text' file.txt (will also be appended, without piping)
$> sed -i '$ a\ here is some more text' file.txt（也将被附加，没有管道）
Gl hf!
高频！

A single greater than character >WRITES output to a file.
单个大于字符>WRITES 输出到文件。
A double character >>APPENDS output into an existing file
