Meld Nautilus 上下文菜单的 Shell 脚本

Beyond Compare 通过使用两个 nautilus 脚本（存储在在 /home/user/.gnome2/nautilus-scripts 中）。

脚本 1：选择进行比较

#!/bin/sh
quoted=$(echo "$NAUTILUS_SCRIPT_SELECTED_FILE_PATHS" | awk 'BEGIN { FS = "\n" } { printf "\"%s\" ", $1 }' | sed -e s#\"\"##)
echo "$quoted" > $HOME/.beyondcompare/nautilus

脚本 2：与选定的比较

#!/bin/sh
arg2=$(cat $HOME/.beyondcompare/nautilus)
arg1=$(echo "$NAUTILUS_SCRIPT_SELECTED_FILE_PATHS" | awk 'BEGIN { FS = "\n" } { printf "\"%s\" ", $1 }' | sed -e s#\"\"##)
bcompare $arg1 $arg2

我正在尝试为 Meld 执行类似的脚本，但它不工作。

我对 shell 脚本不熟悉。谁能帮助我理解这一点：

quoted=$(echo "$NAUTILUS_SCRIPT_SELECTED_FILE_PATHS" | awk 'BEGIN { FS = "\n" } { printf "\"%s\" ", $1 }' | sed -e s#\"\"##)

以便我能够适应融合。

Beyond Compare provides "Select for compare" and "Compare to Selected" by using two nautilus scripts (stored in /home/user/.gnome2/nautilus-scripts).

Script 1: Select for compare

#!/bin/sh
quoted=$(echo "$NAUTILUS_SCRIPT_SELECTED_FILE_PATHS" | awk 'BEGIN { FS = "\n" } { printf "\"%s\" ", $1 }' | sed -e s#\"\"##)
echo "$quoted" > $HOME/.beyondcompare/nautilus

Script 2: Compare to Selected

#!/bin/sh
arg2=$(cat $HOME/.beyondcompare/nautilus)
arg1=$(echo "$NAUTILUS_SCRIPT_SELECTED_FILE_PATHS" | awk 'BEGIN { FS = "\n" } { printf "\"%s\" ", $1 }' | sed -e s#\"\"##)
bcompare $arg1 $arg2

I am trying to do similar scripts for Meld, but it is not working.

I am not familiar with shell scripts. Can anyone help me understand this:

quoted=$(echo "$NAUTILUS_SCRIPT_SELECTED_FILE_PATHS" | awk 'BEGIN { FS = "\n" } { printf "\"%s\" ", $1 }' | sed -e s#\"\"##)

so that I can adapt to meld.

如果您不是为了学习而推出自己的解决方案，我建议您将 diff-ext 扩展安装到 nautilus。它是跨平台的，如果您运行的是 Debian/Ubuntu，安装它应该像 sudo apt-get install diff-ext 一样简单。

在这里查看一些屏幕截图 - http://diff-ext.sourceforge.net/screenshots.shtml

quote=$( ...) 将任何输出分配给名为quoted 的变量，并且可以稍后在脚本中用作 $quoted OR ${quoted} OR "${quoted}" OR "$quoted

" |' char 在 unix/linux 中被称为“管道”，它将前面命令的输出连接到后面的命令中。

所以你只需一次将脚本拆开一小部分，看看它做了什么，

quoted=$(
# I would execute below by itself first
echo "$NAUTILUS_SCRIPT_SELECTED_FILE_PATHS"
# then add on this piped program to see how data gets transformed
| awk 'BEGIN { FS = "\n" } { printf "\"%s\" ", $1 }' 
# then add this
| sed -e s#\"\"##
# the capturing of the output to the var 'quoted' is the final step of code
)

# you **cannot** copy paste this whole block of code and expect it to work ;-)

我不知道 $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS 中应该有什么，所以很难在这里向你展示。并且，该变量未在您在此处指定的任何代码中定义，因此当您echo其值时，您可能只会得到一个空行。准备好研究如何设置该值以及什么是正确的值。

我还注意到您的代码“前缀”为 #!/bin/sh。如果它确实是 /bin/sh，那么像 quoted=$(....) 这样的命令替换将不起作用，并且应该生成错误消息。也许您的系统实际上正在使用 bash 来执行 /bin/sh。您可以通过将 'shebang' 更改为 #! 来消除将来可能出现的任何混乱（当更改为 /bin/sh = bourne shell 的系统时）。 /bin/bash。

我希望这有帮助。

The quoted=$( ...) assigns whatever output there is to the variable named quoted, and can be used later in the script as $quoted OR ${quoted} OR "${quoted}" OR "$quoted"

The '|' char is called a 'pipe' in unix/linux and it connects the output of the preceding command to feed into the following command.

So you just take the script apart 1 piece at a time and see what it does,

quoted=$(
# I would execute below by itself first
echo "$NAUTILUS_SCRIPT_SELECTED_FILE_PATHS"
# then add on this piped program to see how data gets transformed
| awk 'BEGIN { FS = "\n" } { printf "\"%s\" ", $1 }' 
# then add this
| sed -e s#\"\"##
# the capturing of the output to the var 'quoted' is the final step of code
)

# you **cannot** copy paste this whole block of code and expect it to work ;-)

I don't know what is supposed to be in $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS, so it is hard to show you here. AND, that variable is not defined in any of the code you specify here, so you may only get a blank line when you echo its value. Be prepared to do some research on how that value get set AND what are the correct values.

Also I notice that your code is 'prefixed' as #!/bin/sh. If it is truly /bin/sh then command substitution like quoted=$(....) will not work and should generate an error message. Persumably your system is really using bash for /bin/sh. You can eliminate any possible confusion in the future (when changing to a system where /bin/sh = bourne shell), by changing the 'shebang' to #! /bin/bash.

I hope this helps.
