这可能为你工作(GNU sed):

sed -ne '16224,16482w newfile' -e '16482q' file

或者利用bash:

sed -n $'16224,16482w newfile\n16482q' file

awk还有另一种方法:

awk 'NR==16224, NR==16482' file

如果文件很大，最好在读取最后一行之后退出。这样，它就不会不必要地读取以下行:

awk 'NR==16224, NR==16482-1; NR==16482 {print; exit}' file

awk 'NR==16224, NR==16482; NR==16482 {exit}' file

也许，你会给这个简陋的脚本一个机会;-)

#!/usr/bin/bash

# Usage:
#   body n m|-m

from=$1
to=$2

if [ $to -gt 0 ]; then
# count $from the begin of the file $to selected line
    awk "NR >= $from && NR <= $to {print}"
else
# count $from the begin of the file skipping tailing $to lines
    awk '
    BEGIN   {lines=0; from='$from'; to='$to'}
            {++lines}
    NR >= $from {line[lines]=$0}
    END     {for (i = from; i < lines + to + 1; i++) {
                print line[i]
            }
    }'
fi

我已经为sed、perl、head+tail和我自己的awk代码编译了一些最高评级的解决方案，并通过管道关注性能，同时使用LC_ALL=C确保所有候选程序以尽可能快的速度运行，并在两者之间分配2秒的睡眠间隔。

差距是显而易见的:

   abs time    awk/app speed ratio
 ----------------------------------
   0.0672 sec :   1.00x mawk-2
   0.0839 sec :   1.25x gnu-sed
   0.1289 sec :   1.92x perl
   0.2151 sec :   3.20x gnu-head+tail

还没有机会测试这些工具的python或BSD变体。

那些想要计算头部、|、尾部组合的间隔的人是想多了。

下面是如何在不计算任何东西的情况下得到“16224 - 16482”范围:

cat file | head -n +16482 | tail -n +16224

解释:

The + instructs the head/tail command to "go up to / start from" (respectively) the specified line number as counted from the beginning of the file. Similarly, a - instructs them to "go up to / start from" (respectively) the specified line number as counted from the end of the file The solution shown above simply uses head first, to 'keep everything up to the top number', and then tail second, to 'keep everything from the bottom number upwards', thus defining our range of interest (with no need to compute an interval).

您可以使用'vi'，然后使用以下命令:

:16224,16482w!/tmp/some-file

另外:

cat file | head -n 16482 | tail -n 258

编辑:-只是补充解释，您使用head -n 16482显示前16482行，然后使用tail -n 258显示第一次输出的最后258行。
