编辑/分割/保存数据在文本文件中
我有一个名为 playlist.pls 的文本文件，它是动态创建的，在该文本文件中我有数千行，如下所示：
File000001=/home/ubu32sc/Documents/octave/pre/wavefn_0001.wav
File000002=/home/ubu32sc/Documents/octave/pre/wavefn_0002.wav
File000003=/home/ubu32sc/Documents/octave/pre/wavefn_0003.wav
File000004=/home/ubu32sc/Documents/octave/pre/wavefn_0004.wav
File000005=/home/ubu32sc/Documents/octave/pre/wavefn_0005.wav
File000006=/home/ubu32sc/Documents/octave/pre/wavefn_0006.wav
File000007=/home/ubu32sc/Documents/octave/pre/wavefn_0007.wav
File000008=/home/ubu32sc/Documents/octave/pre/wavefn_0008.wav
File000009=/home/ubu32sc/Documents/octave/pre/wavefn_0009.wav
File000010=/home/ubu32sc/Documents/octave/pre/wavefn_0010.wav etc...
我需要将文本文件中的数据拆分为几个不同的文件。 示例：
The play1.pls file would contain:
File000001=/home/ubu32sc/Documents/octave/pre/wavefn_0001.wav
File000002=/home/ubu32sc/Documents/octave/pre/wavefn_0002.wav
File000003=/home/ubu32sc/Documents/octave/pre/wavefn_0003.wav
The play2.pls file would contain:
File000004=/home/ubu32sc/Documents/octave/pre/wavefn_0004.wav
File000005=/home/ubu32sc/Documents/octave/pre/wavefn_0005.wav
File000006=/home/ubu32sc/Documents/octave/pre/wavefn_0006.wav
The play3.pls file would contain:
File000007=/home/ubu32sc/Documents/octave/pre/wavefn_0007.wav
File000008=/home/ubu32sc/Documents/octave/pre/wavefn_0008.wav
File000009=/home/ubu32sc/Documents/octave/pre/wavefn_0009.wav
The play4.pls file would contain:
File000010=/home/ubu32sc/Documents/octave/pre/wavefn_0010.wav etc...
执行此操作的最佳方法是什么我正在考虑使用 Octave/Matlab 来执行此操作，但我认为在包含数十数千行的文本文件上运行 for 循环会过度消耗和资源密集型。 grep 或 perl 是否适合使用，或者我应该使用其他类型的程序？如果是这样我该怎么做呢？
我正在使用 Ubuntu 32 10.04 6 gig 内存 谢谢
I have a text file called playlist.pls which is dynamically created, and in the text file I have thousands of lines that look like this:
File000001=/home/ubu32sc/Documents/octave/pre/wavefn_0001.wav
File000002=/home/ubu32sc/Documents/octave/pre/wavefn_0002.wav
File000003=/home/ubu32sc/Documents/octave/pre/wavefn_0003.wav
File000004=/home/ubu32sc/Documents/octave/pre/wavefn_0004.wav
File000005=/home/ubu32sc/Documents/octave/pre/wavefn_0005.wav
File000006=/home/ubu32sc/Documents/octave/pre/wavefn_0006.wav
File000007=/home/ubu32sc/Documents/octave/pre/wavefn_0007.wav
File000008=/home/ubu32sc/Documents/octave/pre/wavefn_0008.wav
File000009=/home/ubu32sc/Documents/octave/pre/wavefn_0009.wav
File000010=/home/ubu32sc/Documents/octave/pre/wavefn_0010.wav etc...
I need to have the data in the text file split into several different files.
example:
The play1.pls file would contain:
File000001=/home/ubu32sc/Documents/octave/pre/wavefn_0001.wav
File000002=/home/ubu32sc/Documents/octave/pre/wavefn_0002.wav
File000003=/home/ubu32sc/Documents/octave/pre/wavefn_0003.wav
The play2.pls file would contain:
File000004=/home/ubu32sc/Documents/octave/pre/wavefn_0004.wav
File000005=/home/ubu32sc/Documents/octave/pre/wavefn_0005.wav
File000006=/home/ubu32sc/Documents/octave/pre/wavefn_0006.wav
The play3.pls file would contain:
File000007=/home/ubu32sc/Documents/octave/pre/wavefn_0007.wav
File000008=/home/ubu32sc/Documents/octave/pre/wavefn_0008.wav
File000009=/home/ubu32sc/Documents/octave/pre/wavefn_0009.wav
The play4.pls file would contain:
File000010=/home/ubu32sc/Documents/octave/pre/wavefn_0010.wav etc...
What's the best way to go about doing this I was thinking about using octave/matlab to do this but I think this would be over kill and resource intensive to run a for loop on a text file with 10's of thousands of lines. Is grep or perl the proper thing to use and or should I use another type of program? and if so how could I do this with it?
I'm using Ubuntu 32 10.04 6 gig ram
Thanks

正如您所提到的，如果您只想将一个文本文件拆分为多个文件，Matlab / Octave 似乎有点矫枉过正。
有一千种方法可以做到这一点（特别是在 UNIX 系统上），所以只需选择你的方法即可。
一种可能性是使用
split是这样的：As you mentionned it, Matlab / Octave seems to be an overkill if you just want to split a text file into multiple files.
There are a thousand ways to do this (espcially on a unix system) so just pick yours.
One of the possibilities is to use
splitwhich goes like this:
