Question

我想按字节分割文件，同时通过

保持完整行

split -C <bytes> filename

但是，默认拆分不接受-C

split: illegal option -- C
usage: split [-a sufflen] [-b byte_count] [-l line_count] [-p pattern]
             [file [prefix]]

我brew install coreutils，looks like it should support what I want。

如何更改拆分以使用coreutils？

Answer 1

brew install coreutils将安装以＆＃39; g＆＃39;为前缀的命令默认情况下。因此，如果您输入split，gsplit应该可用。您可以使用选项--with-default-names安装包，以正常名称安装命令。

Answer 2

发现它！

brew info coreutils
...
==> Caveats
All commands have been installed with the prefix 'g'.

所以它只是gsplit -C $BYTES filename

Answer 3

请转到文件的路径并执行以下命令分割-b 500m inputFile output_files.split.txt

示例

split -b 500m sample.txt output_files.split.txt

Answer 4

--with-default-names已从brew中删除，因此，如果您需要使用正常名称运行一个命令，则需要在路径中添加一些内容。见下文

brew info coreutils
...
==> Caveats
Commands also provided by macOS have been installed with the prefix "g".
If you need to use these commands with their normal names, you
can add a "gnubin" directory to your PATH from your bashrc like:
   PATH="/usr/local/opt/coreutils/libexec/gnubin:$PATH"

Mac bash拆分不能按行字节拆分
