1.分割 -- split命令 可以指定按行数分割和按字节大小分割两种模式。 (1) 按行数分割 $ split -l 300 large_file.txt new_file_prefix 加上-d,使用数字后缀;加上--verbose,显示分割进度: $ split -l50000 -d large_file.txt part_ --verbose (2) 按字节大小分割 $ split
“p” command prints the buffer (remember to use -n option with “p”) “d” command is just opposite, its for deletion. ‘d’ will delete the pattern space buffer and immediately starts the next cycle. :删除从第4行到第8行 $sed 4,8d thegeekstuff.txt 命令:split -l 300 large_file....

sed[-nefri]‘command’ 输入文本 常用选项:-n∶使用安静(silent)模式。在一般 sed 的用法中,所有来自STDIN的资料一般都会被列出到萤幕上。但如果加上-n 参数后,则只有经过sed特殊处理的那一行(或者动作)才会被列出来。-e∶直接在指令列模式上进行 sed 的动作编辑;-f∶直接将 sed 的动作写在一个档案内,-...
As does any command with redirected output, this sends some stuff from the standard output to a file. However, the file is /dev/null, a device, and the kernel decides what to do with any data written to this device. In the case of /dev/null, the kernel simply ignores the input and...
Thesplitcommand would seem to be most useful for programmers. It's used to split a large file into smaller chunks, with 1000 lines being the default chunk size. Because 1000 lines are far too long to show in this article, here's what I did to demonstrate the split command for myself:...

Runtime equivalent of the classic static ldd command and because the system pldd command often fails to attach to a process random_select.sh - selects one of given args at random. Useful for sampling, running randomized subsets of large test suites etc. random_number.sh - prints a random ...
