文本处理，谁能帮我下。用shell实现。

[chengmoYS]

以“--”为分界线
把以下文本输出3个独立的文件
“--”是分割符，2个“--”把文本分割成3个文件
shell实现
谢谢

[枫叶饭团]

用python比较好写，恩恩。bash不会。。。

[qy117121]

码盲路过

[xyy_xx]

awk -F 结合管道 可以办到

[Jr.z]

sed -n '1,/--/p' filename | sed '/--/d' > file1

sed -n '/--/,/--/p' filename | sed '/--/d' > file2

sed '1,/--/d' filename | sed '1,/--/d' > file3

[eexpress]

awk

awk -F'Section' 'BEGIN{RS = ""} /.*\"Screen\"/ ' /etc/X11/xorg.conf

你这类似。

[chengmoYS]

这个是我用shell写的 sed awk还不熟悉

lshal | grep -A65 "scsi.type = 'cdrom'" | sed '/^$/d'> $TEMP/lshal_cdrom.$$


while read LINE
do
echo "$LINE" >> $TEMP/lshal_cdrom$NUMBER.$$
if [ "$LINE" = "--" ]
then
NUMBER=`expr $NUMBER - 1 | bc`
fi
done < $TEMP/lshal_cdrom.$$

[eexpress]

你会shell。那还问啥。自己写。

[aerofox]

代码： 全选

csplit file '/--/' '{*}'

[xyy_xx]

代码： 全选

sed -e '/^$/d' yourfile|awk -F "--"  'BEGIN{RS=""} { for (i=1; i<=NF; i++) print $i>i }'

[fnan]

如果不包括分割行：
awk -v n=1 '/^--$/{n++;next};{print $0>>n".txt"}' file

[Jr.z]

代码： 全选

csplit file '/--/' '{*}'

不错，之前不知道还有这个，看你发贴总能学到东西

[xiooli]

代码： 全选

for n, l in enumerate(open('file').read().split('--')): open('%s.txt' %n, 'w').write(l)

[chengmoYS]

谢谢大家啊 我也学到了啊

特别感谢aerofox那个命令 很好

[ubuntu_vivi]

csplit 原来还有这等神器，学习了～

Usage: csplit [OPTION]... FILE PATTERN...
Output pieces of FILE separated by PATTERN(s) to files `xx00', `xx01', ...,
and output byte counts of each piece to standard output.

Mandatory arguments to long options are mandatory for short options too.
-b, --suffix-format=FORMAT use sprintf FORMAT instead of %02d
-f, --prefix=PREFIX use PREFIX instead of `xx'
-k, --keep-files do not remove output files on errors
-n, --digits=DIGITS use specified number of digits instead of 2
-s, --quiet, --silent do not print counts of output file sizes
-z, --elide-empty-files remove empty output files
--help display this help and exit
--version output version information and exit

Read standard input if FILE is -. Each PATTERN may be:

INTEGER copy up to but not including specified line number
/REGEXP/[OFFSET] copy up to but not including a matching line
%REGEXP%[OFFSET] skip to, but not including a matching line
{INTEGER} repeat the previous pattern specified number of times
{*} repeat the previous pattern as many times as possible
