批量替换空格特殊符号文件名的脚本

Question

比如下面csv目录中的文件
lf-orders-2018-11-20（1700).csv
lf-orders-2018-11-20 17002.csv

文件名中带有空格，和夹杂着中英文圆括号，需要将他们替换为下划线_
生成下面的：
lf-orders-2018-11-20_1700_.csv
lf-orders-2018-11-20_17002.csv

SAVEIFS=$IFS
IFS=$'\n'
for file in `ls csv | grep .csv`
do
 newfile=`echo ${file} | sed 's/ /_/g'| sed 's/（/_/g'| sed 's/)/_/g'`
 # echo $newfile
 mv csv/$file csv/$newfile
done
# revert IFS
IFS=$SAVEIFS

我现在已经有了上面的脚本，不太好用，
会报mv: cannot stat 'csv/lf-orders-2018-11-20 17002 .csv'$'\n''lf-orders-2018-11-20'$'\357\274\210''1700).csv': No such file or directory

求更简洁的写法，谢谢！

Answer 1

rename命令了解下

Answer 2

把下面两条命令在csv文件所在目录都执行一下。

ls *.csv|sed -r 's/(.*)（([^)]+)\)(.*)/mv "&" \1_\2_\3/e'
ls *.csv|sed -r 's/(.*)\s+(.*)/mv "&" \1_\2/e'

测试：

回答题主评论里的问题，远程到别的机器上执行方法：

ssh lft "ls csv/*.csv|sed -r 's/(.*)（([^)]+)\)(.*)/mv \"&\" \1_\2_\3/e'"
ssh lft "ls csv/*.csv|sed -r 's/(.*)\s+(.*)/mv \"&\" \1_\2/e'"

既然你都打算用脚本来处理了，那为啥不用python呢？
python轻松搞定，脚本如下：

#!/usr/bin/env python3
#-*- coding: utf-8 -*-

import sys
import os
import re

def main():

    path = sys.argv[1]
    for dirpath, dirnames, filenames in os.walk(path):
        for filename in filenames:
            newname = re.sub('[ 　\(（]+', '_', filename)
            newname = re.sub('[\)）]+', '', newname)
            if filename != newname:
                print('rename> {}: {} => {}'.format(dirpath, filename, newname))
                os.rename(os.path.join(dirpath, filename), os.path.join(dirpath, newname))

if __name__ == '__main__':
    main()

测试执行结果如下：

$ find csv
csv
csv/lf-orders-2018-11-20 17002.csv
csv/ccc
csv/ccc/lf-orders-2018-11-20 17002.csv

csv/ccc/csv/ccc/lf-orders-2018-11-20 17002.csv
csv/lf-orders-2018-11-20（1700).csv
$ ./z.py csv
rename> csv: lf-orders-2018-11-20 17002.csv => lf-orders-2018-11-20_17002.csv
rename> csv: lf-orders-2018-11-20（1700).csv => lf-orders-2018-11-20_1700.csv
rename> csv/ccc: lf-orders-2018-11-20 17002.csv => lf-orders-2018-11-20_17002.csv

rename> csv/ccc/csv/ccc: lf-orders-2018-11-20 17002.csv => lf-orders-2018-11-20_17002.csv
$ find csv

Answer 4

for name in ./*;do mv "${name}" "${name// /}";done

一行 shell 的事....干嘛整那么麻烦
