# print section of file based on line numbers
 sed -n '16224 ,16482p'               # method 1
 sed '16224,16482!d'                 # method 2

sed -n '16224,16482p;16483q' filename > newfile

来自sed手册:

p - Print out the pattern space (to the standard output). This command is usually only used in conjunction with the -n command-line option. n - If auto-print is not disabled, print the pattern space, then, regardless, replace the pattern space with the next line of input. If there is no more input then sed exits without processing any more commands. q - Exit sed without processing any more commands or input. Note that the current pattern space is printed if auto-print is not disabled with the -n option.

sed脚本中的地址可以是以下任何一种形式: 数量 指定行号将只匹配输入中的该行。 一个地址范围可以通过指定两个地址来指定 用逗号(，)分隔。地址范围匹配从 第一个地址匹配，并一直持续到第二个 地址匹配(包括)。

我编写了一个小型bash脚本，您可以从命令行运行它，只要您更新PATH以包含它的目录(或者您可以将它放在PATH中已经包含的目录中)。

用法:$ pinch filename起始行结束行

sed -n '16224,16482 p' orig-data-file > new-file

其中16224、16482是起始行号和结束行号，包括。这是1索引。-n抑制将输入回显为输出，这显然不是你想要的;数字表示要执行以下命令的行范围;命令p输出相关的行。

使用head/tail非常简单:

head -16482 in.sql | tail -258 > out.sql

使用sed:

sed -n '16224,16482p' in.sql > out.sql

使用awk:

awk 'NR>=16224&&NR<=16482' in.sql > out.sql

perl -ne 'print if 16224..16482' file.txt > new_file.txt
