如何在Windows中拆分大文本文件? [英] How to split large text file in windows?
问题描述
我有一个大小为 2.5 GB 的日志文件.有没有办法使用 Windows 命令提示符将此文件拆分为更小的文件?
如果你已经安装了
在这张图中可以看到split
生成的文件被命名为xaa
、xab
、<代码>xac 等
这些名称由前缀和后缀组成,您可以指定它们.由于我没有指定我希望前缀或后缀的外观,因此前缀默认为 x
,后缀默认为两个字符的字母枚举.
另一个例子:
这个例子演示了
- 使用
MySlice
的文件名前缀(而不是默认的x
), -d
标志用于使用数字后缀(而不是aa
、ab
、ac
等...),- 和选项
-a 5
告诉它我希望后缀长度为 5 位:
I have a log file with size of 2.5 GB. Is there any way to split this file into smaller files using windows command prompt?
If you have installed Git for Windows, you should have Git Bash installed, since that comes with Git.
Use the split
command in Git Bash to split a file:
into files of size 500MB each:
split myLargeFile.txt -b 500m
into files with 10000 lines each:
split myLargeFile.txt -l 10000
Tips:
If you don't have Git/Git Bash, download at https://git-scm.com/download
If you lost the shortcut to Git Bash, you can run it using
C:Program FilesGitgit-bash.exe
That's it!
I always like examples though...
Example:
You can see in this image that the files generated by split
are named xaa
, xab
, xac
, etc.
These names are made up of a prefix and a suffix, which you can specify. Since I didn't specify what I want the prefix or suffix to look like, the prefix defaulted to x
, and the suffix defaulted to a two-character alphabetical enumeration.
Another Example:
This example demonstrates
- using a filename prefix of
MySlice
(instead of the defaultx
), - the
-d
flag for using numerical suffixes (instead ofaa
,ab
,ac
, etc...), - and the option
-a 5
to tell it I want the suffixes to be 5 digits long:
