我正准备发布头部/尾部技巧，但实际上我可能只是启动emacs。: -)

Esc-x goto-line ret 16224 马克(ctrl-space) Esc-x goto-line ret 16482 esc-w

打开新的输出文件ctl-y 保存

让我看看发生了什么。

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

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。

站在拳击手的肩膀上，我喜欢这样:

sed -n '<first line>,$p;<last line>q' input

e.g.

sed -n '16224,$p;16482q' input

$表示“最后一行”，因此第一个命令使sed打印从第16224行开始的所有行，第二个命令使sed在打印第16428行之后退出。(在boxxar的解决方案中，为q范围添加1似乎没有必要。)

我喜欢这个变体，因为我不需要两次指定结束行号。而且我认为使用$不会对性能产生不利影响。

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。
