bash 如何在 Mac OS 10.10+ 上使用 GNU sed，不再支持“brew install --default-names”

How to use GNU sed on Mac OS 10.10+, 'brew install --default-names' no longer supported

提问by user3781201

Under Mac OS 10.10.3, I installed gnu-sed by typing:

在 Mac OS 10.10.3 下，我通过键入以下内容安装了 gnu-sed：

brew install gnu-sed --default-names

When I type it again, I get the message:

当我再次输入时，我收到消息：

gnu-sed-4.2.2 already installed

gnu-sed-4.2.2 已经安装

However, even after rebooting the system and restarting Terminal, I still cannot use the GNU version of sed. For example:

但是，即使在重新启动系统并重新启动终端后，我仍然无法使用 sed 的 GNU 版本。例如：

echo a |?sed 's_A_X_i'

returns: bad flag in substitution command 'i'

返回：替换命令“i”中的错误标志

What should I do to get the GNU version working? Here are the paths in my $PATH variable.

我应该怎么做才能使 GNU 版本正常工作？这是我的 $PATH 变量中的路径。

/Users/WN/-myUnix
/opt/local/bin
/opt/local/sbin
/usr/bin
/bin
/usr/sbin
/sbin
/usr/local/bin
/Applications/calibre.app/Contents/MacOS
/opt/ImageMagick/bin
/usr/texbin 

I'm sorry if my question seems obvious, but I am learning shell scripting on my own and don't quite understand yet how UNIX programs are installed. Any help to use GNU compliant commands (in this case sed, but soon I'll need others as well) on my Mac without causing damage or unnecessary clutter would be greatly appreciated.

如果我的问题看起来很明显，我很抱歉，但我正在自己学习 shell 脚本并且不太了解 UNIX 程序是如何安装的。在我的 Mac 上使用 GNU 兼容命令（在这种情况下为 sed，但很快我也需要其他命令）而不会造成损坏或不必要的混乱的任何帮助将不胜感激。

Note (2019):

注（2019）：

The --with-default-namesoption is removedsince January 2019, so now that option is not available anymore.

该--with-default-names选项自 2019 年 1 月起被删除，因此现在该选项不再可用。

When installing, Homebrew instructs on how to adapt the path, if one wants to use sed without the gprefix.

安装时，Homebrew 会指示如何调整路径，如果您想使用不带g前缀的sed 。

You already have the gnu-sed installed without the --with-default-namesoption.

您已经安装了没有该--with-default-names选项的 gnu-sed 。

• With --with-default-namesoption it installs sedto /usr/local/bin/
• Without that option it installs gsed

• 使用--with-default-names选项安装sed到/usr/local/bin/
• 如果没有该选项，它会安装 gsed

So in your case what you gotta do is:

所以在你的情况下你要做的是：

$ brew uninstall gnu-sed
$ brew install gnu-sed --with-default-names

Update path if needed...

如果需要，更新路径...

$ echo $PATH | grep -q '/usr/local/bin'; [ $? -ne 0 ] && export PATH=/usr/local/bin:$PATH
$ echo a | sed 's_A_X_i'

or use gsedas others suggested.

或gsed按照其他人的建议使用。

When you install the GNU version of sedfor Mac OS X using:

当您使用以下命令安装sedMac OS X的 GNU 版本时：

$ brew install gnu-sed

The program that you use is gsed.

您使用的程序是gsed.

So for example:

例如：

$ echo "Calimero is a little chicken" > test
$ cat test
Calimero is a little chicken
$ gsed -i "s/little/big/g" test
$ cat test
Calimero is a big chicken

Also, to compliment the use of GNU command tools on Mac OS X, there is a nice blog post here to get the tools from linux:

此外，为了赞美在 Mac OS X 上使用 GNU 命令工具，这里有一篇不错的博客文章可以从 linux 获取这些工具：

The sedthat ships with OS X is in /usr/bin.

该sed附带OS X中/usr/bin。

The sedthat homebrewinstalls is in /usr/local/bin.

在sed这homebrew安装在/usr/local/bin。

If you prefer to use the homebrewone, you have two options:

如果您更喜欢使用其中homebrew一种，您有两种选择：

Option 1

选项1

Every time you want to use homebrewsed, type

每次要使用时homebrewsed，请键入

/usr/local/bin/sed

or, preferably

或者，最好

Option 2

选项 2

Move /usr/local/bin/ahead (i.e. before) /usr/binin your PATH in your login profile, like this

移动/usr/local/bin/提前（即前）/usr/bin在PATH中的登录配置，这样

 export PATH=/usr/local/bin:<other places>

$ brew install gnu-sed

$ brew install gnu-sed

$ export PATH="/usr/local/opt/gnu-sed/libexec/gnubin:$PATH"

With these two commands gnu-sed works properly

使用这两个命令 gnu-sed 可以正常工作

回答by imechemi

If you need to use gnu-sed command with their normal names, you can add a "gnubin" directory to your PATH from your bashrc. Just use the following command in your bash or terminal.

如果您需要使用具有正常名称的 gnu-sed 命令，您可以从您的 bashrc 向您的 PATH 添加一个“gnubin”目录。只需在 bash 或终端中使用以下命令。

export PATH="/usr/local/opt/gnu-sed/libexec/gnubin:$PATH"

--with-default-namesdidn't work for me on Mac OS X 10.14.2 so I created a symlink named sedto gsedhigher in the $PATH

--with-default-names没有对我来说有效在Mac OS X 10.14.2所以我创建了一个名为符号链接sed到gsed在较高$PATH

I also created a symlink named sed.1to the gsed.1manpage higher in the $MANPATHso manwould access the gsedmanpage instead of the default sedmanpage

我还创建了一个符号链接，命名sed.1为gsed.1更高的联机帮助页，$MANPATH以便man访问gsed联机帮助页而不是默认sed联机帮助页
