我写了一个叫做splitter的Haskell程序，它就是这样做的:阅读我发布的博客文章。

您可以使用该程序如下:

$ cat somefile | splitter 16224-16482

这就是它的全部。您将需要Haskell来安装它。只是:

$ cabal install splitter

这样就做完了。我希望这个程序对您有用。

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

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

#!/bin/bash
# Display line number ranges of a file to the terminal.
# Usage: $ pinch filename start-line end-line
# By Evan J. Coon

FILENAME=$1
START=$2
END=$3

ERROR="[PINCH ERROR]"

# Check that the number of arguments is 3
if [ $# -lt 3 ]; then
    echo "$ERROR Need three arguments: Filename Start-line End-line"
    exit 1
fi

# Check that the file exists.
if [ ! -f "$FILENAME" ]; then
    echo -e "$ERROR File does not exist. \n\t$FILENAME"
    exit 1
fi

# Check that start-line is not greater than end-line
if [ "$START" -gt "$END" ]; then
    echo -e "$ERROR Start line is greater than End line."
    exit 1
fi

# Check that start-line is positive.
if [ "$START" -lt 0 ]; then
    echo -e "$ERROR Start line is less than 0."
    exit 1
fi

# Check that end-line is positive.
if [ "$END" -lt 0 ]; then
    echo -e "$ERROR End line is less than 0."
    exit 1
fi

NUMOFLINES=$(wc -l < "$FILENAME")

# Check that end-line is not greater than the number of lines in the file.
if [ "$END" -gt "$NUMOFLINES" ]; then
    echo -e "$ERROR End line is greater than number of lines in file."
    exit 1
fi

# The distance from the end of the file to end-line
ENDDIFF=$(( NUMOFLINES - END ))

# For larger files, this will run more quickly. If the distance from the
# end of the file to the end-line is less than the distance from the
# start of the file to the start-line, then start pinching from the
# bottom as opposed to the top.
if [ "$START" -lt "$ENDDIFF" ]; then
    < "$FILENAME" head -n $END | tail -n +$START
else
    < "$FILENAME" tail -n +$START | head -n $(( END-START+1 ))
fi

# Success
exit 0

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
