我有一个包含大文本文件的文件夹。每个文件都是由[[文件名]]分隔的1000个文件的集合。我想拆分文件并从中制作1000个文件并将它们放在一个新文件夹中。 bash有没有办法做到这一点？任何其他快速方法也可以。
for f in $(find . -name '*.txt')
do mkdir $f
mv
cd $f
awk '/[[.*]]/{g++} { print $0 > g".txt"}' $f
cd ..
done

虽然不是由醉酒者写的和写的，但不能保证工作。
import re
import sys
def main():
pattern = re.compile(r'\[\[(.+)]]')
with open (sys.argv[1]) as f:
for line in f:
m = re.search(pattern, line)
if m:
try:
with open(fname, 'w+') as g:
g.writelines(lines)
except NameError:
pass
fname = m.group(1)
lines = []
else:
lines.append(line)
with open(fname, 'w+') as g:
g.writelines(lines)
if __name__ == '__main__':
main()

您正在尝试创建一个与现有文件名称相同的文件夹。
for f in $(find . -name '*.txt')
do mkdir $f
此处，“find”将列出当前路径中的文件，对于每个文件，您将尝试创建具有完全相同名称的目录。一种方法是首先创建一个临时文件夹：
for f in $(find . -name '*.txt')
do mkdir temporary # create a temporary folder
mv $f temporary # move the file into the folder
mv temporary $f # rename the temporary folder to the name of the file
cd $f # enter the folder and go on....
awk '/[[.*]]/{g++} { print $0 > g".txt"}' $f
cd ..
done
请注意，您的所有文件夹都将使用“.txt”扩展名。如果您不想这样，可以在创建文件夹之前将其剪掉;这样，您将不需要临时文件夹，因为您尝试创建的文件夹与.txt文件具有不同的名称。 例如：
for f in $(find . -name '*.txt' | rev | cut -b 5- | rev)

编写一个bash脚本。在这里，我已经为你完成了。
请注意此脚本的结构和功能：
usage()函数中的作用，该函数用于-h选项。-h，-n，-v。getopts进行选项处理$verbose模式下用户会发生什么。-n选项，$norun模式）。run功能，该功能会关注$norun，$verbose和$quiet变量。我不只是为你钓鱼，而是教你如何捕鱼。
祝你好运下一个bash脚本。

#!/bin/bash
# split-collections IN-FOLDER OUT-FOLDER
PROG="${0##*/}"
usage() {
cat 1>&2 <<EOF
usage: $PROG [OPTIONS] IN-FOLDER OUT-FOLDER
This script splits a collection of files within IN-FOLDER into
separate, named files into the given OUT-FOLDER. The created file
names are obtained from formatted text headers within the input
files.
The format of each input file is a set of HEADER and BODY pairs,
where each HEADER is a text line formatted as:
[[input-filename1]]
text line 1
text line 2
...
[[input-filename2]]
text line 1
text line 2
...
Normal processing will show the filenames being read, and file
names being created. Use the -v (verbose) option to show the
number of text lines being written to each created file. Use
-v twice to show the actual lines of text being written.
Use the -n option to show what would be done, without actually
doing it.
Options
-h Show this help
-n Dry run -- do NOT create any files or make any changes
-o Overwrite existing output files.
-v Be verbose
