如果需要重复处理文件的操作,手动选择往往低效,繁琐,这种情况往往可以写一个脚本来处理.所以学会写批处理脚本能大大提高效率,为此特地花了点时间总结下批处理脚本的编写,并写了几个例子,以供查阅.
python os and os.path module
os.mkdir(dirPath)
os.system("terminal command")
os.rename(filename, Newfilename)
os.path.listdir(path)
os.path.join(os.getcwd(), 'folder')
os.path.exists(path)
os.path.abspath(path) #绝对路径
os.path.basename(path) #文件名
os.path.split(path) #return (head,tail), path = join(head, tail)，父目录与文件名分离
os.path.splitext(path) # return (root, ext), root + ext = path， 扩展名分离
Matlab批处理脚本
str_prefix = pwd;
str_prefix = fullfile(str_prefix, 'images');
fileList = dir([str_prefix, '/TP*']);
% for i = 1:length(file)
% fprintf('%s\n',tmp(i).name)
% end
for i = 1:length(fileList)
filepath = fullfile(str_prefix, fileList(i).name);
LJ_demo1(filepath);
end
Python批处理脚本
# coding:utf-8
import sys
import os
def main():
'''
批处理文件,如序列化重命名文件
:return:
'''
# os.system("mkdir images")
# os.system("touch images/a.jpg images/b.jpg images/c.jpg")
print sys.version
path = os.getcwd()
if not os.path.exists('./images'):
print "not exist " + os.path.join(path, "images")
return
prefix = os.path.join(path, "images")
i = 1
for file in os.listdir(prefix):
[root, ext] = os.path.splitext(file)
if ext == '.jpg':
newname = str(i) + ext
os.rename(os.path.join(prefix, file), os.path.join(prefix, newname))
print "rename:", file, "->", newname
i += 1
if __name__ == '__main__':
main()
