我需要在某个嵌套目录中查找所有文件，并使用这些文件对同一目录中的project.updated文件进行内容替换。project.json

我正在使用 BusyBox (1.33.1)。

/apps
    /project1
        project.json
        project.updated
    /project2
        project.json

如您所见，project.updatedproject1 文件夹中有一个文件。此文件的内容应替换project.json文件。

这只有在我知道确切文件的情况下才有效：

cat /apps/project1/project.updated > /apps/project1/project.json

我如何以动态方式执行此操作，因为有很多项目并且其中只有少数有project.updated文件？

--build-arg我需要在busybox shell 中使用一些键/值对（build.args 文件）来构建参数字符串：

脚本.sh

#!/bin/sh
one=$1
two=$2
shift

while IFS= read -r line; do
    set "$@" --build-arg "$line"
done < "build.args"

echo "$@"

构建.args

ONE=first
TWO=second

运行sh script.sh foo bar（是的，脚本需要两个参数）应该读取 build.args 的内容并添加键/值对作为--build-arg参数并输出这个生成的字符串。这是我所期待的：

--build-arg ONE=first --build-arg TWO=second

但是用我的脚本我确实得到了

bar --build-arg ONE=first --build-arg TWO=second

asbar在脚本调用中作为第二个参数传递。

我正在使用这个 .ssh/config：

Host myserver
    HostName 12.34.67.89
    User anyuser
    IdentityFile /root/.ssh/anything_rsa

但是运行ssh myserver会返回Permission denied (publickey)错误。

为什么不使用给定的身份文件 ( root/.ssh/anything_rsa)？相反，它似乎使用/root/.ssh/id_rsa

跑步ssh -v -i /root/.ssh/anything_rsa -l anyuser myserver是有效的。所以似乎配置文件没有正确使用......我根本不明白......

我正在尝试编写一个小脚本来安装最新的 nodeJS 版本。这就是我开始的方式：

NODE="$(curl -sL https://nodejs.org/dist/latest | grep 'armv6l.tar.gz' | cut -d'"' -f2)" &&
wget https://nodejs.org/dist/latest/$NODE &&
tar -xzf $NODE

对于接下来的步骤，我需要做类似的事情node-v8.12.0-linux-armv6l/bin/node -v，如果它返回一个我想做的值

$ cd node-v8.12.0-linux-armv6l/
$ sudo cp -R * /usr/local/

我的问题是，它$NODE有完整的文件名——包括文件扩展名。但是对于我需要替换的命令node-v8.12.0-linux-armv6l。我也不知道如何检查返回的版本值。

bash ubuntu
