我正在尝试仅从文件（output.txt）到while循环的1到1000行。
我已经尝试过这样的事情：
#!/bin/bash
while read -r line; do
echo "$line"
done < (sed -n 1,1000p data/output.txt)
$ make dependencies
在我的 Mac 终端中给出
make: lsb_release: Command not found
这是完整的消息：
make: lsb_release: Command not found

/bin/bash: md5sum: command not found

我安装了 GNU Make 3.81。另外，我做了：
$ xcode-select -p
/Applications/Xcode.app/Contents/Developer
$ gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 7.3.0 (clang-703.0.29)

Thread model: posix

我在 Mac OS X 上。它可以链接到 zsh，因为我不久前安装了它，我相信我所有与 xcode 相关的工具以前都运行得很好。
感谢您的任何帮助或指示，可以为我指明解决此问题的正确方向。
