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

我会用:

awk 'FNR >= 16224 && FNR <= 16482' my_file > extracted.txt

FNR包含从文件中读取的行的记录(行)号。

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

又快又脏:

head -16428 < file.in | tail -259 > file.out

可能不是最好的方法，但应该有用。

顺便说一下:259 = 16482-16224+1。

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

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).
