ftool

by ShadowlessWalker

简介

ftool(file tool)是一个python小工具,提供了一些批量、灵活处理文件的功能。

安装

可以直接下载源码去运行(需要切换目录,稍微麻烦一点);

推荐下载编译好的 ftool-0.2-py3-none-any.whl 包,使用pip install ftool-0.2-py3-none-any.whl安装,然后就可以直接运行如下命令:

python -m ftool 选项和参数

使用教程

批量重命名文件

命令格式:

ftool [-t] --renames rootdir srcPattern dstPattern

-t:测试模式,在测试模式下,只输出重命名过程信息,不执行实际重命名操作,可用于检查命令正确与否。

rootdir:目录名,该目录下的所有文件将被重命名,当前目录用"."表示。

srcPattern:要匹配的原方件名模板,使用python正则表达式语法,只有文件名匹配的的文件会被重命名。这个参数的另一个重要作用是可以从原文件名中提取出部分字符串(以()括起来的子表达式的匹配结果将作为参数提供给新文件名),提取出的子字符串可以用在新文件名中。下面举几个例子:

原文件名 srcPattern 意义 提取出的参数
abc.S01E01.mp4 .* 匹配任何文件名
abc.S01E01.mp4 (S\d+E\d+) 匹配包含SmEn样式的文件名 S01E01
abc第1季第15集.mp4 第(\d+)第(\d+) 匹配包含第m季第n集样式的文件名 1,15
abc第1季第15集.mp4 .(..).*第(\d+) 匹配包含第n样式的文件名,并提取第2-3字符 bc,15

dstPattern:新文件名模板,使用python的format格式化语法。模板中可以使用以{}括起来的变量或参数。

例如:my-{0}-{C}-{1}{surfix},其中:

  • {0}表示srcPattern中提取出的第1个参数;

  • {1}表示srcPattern中提取出的第2个参数;

  • {C}是程序预置的一个计数器变量,每扫描到一个匹配文件,其值自动加1;

  • {surfix}是程序预置的一个变量,表示原文件名的后缀部分(包含.);

    默认的文件名模板是{C:02}{surfix},表达以2位数字重命名文件,并保留文件后缀。


假设有以下目录:

test/

| ----/abcS01E01def256.mp4

|----/abcdeS01E02def365.mp4

|----/abcfffffffS01E03fiiienifnsifn.mp4

|----/abc.txt


把test目录下的所有文件统一重命名为以数字编号的样式:

cd test  #切换到test目录
ftool.py --renames .  #使用了默认参数

test/ #重命名的结果如下:

| ----/00.mp4

|----/01.mp4

|----/02.mp4

|----/03.txt


现在我们只把test目录下的所有mp4文件重命名为以数字编号的样式:

cd test   #切换到test目录
ftool.py --renames . (mp4)

test/ #重命名的结果如下:

| ----/00.mp4

|----/01.mp4

|----/02.mp4

|----/abc.txt #txt文件名保持不变


现在我们来个稍微复杂一点的,把test目录下的所有mp4文件重命名为"abc-S01E01.mp4"的样式:

cd test   #切换到test目录
ftool.py --renames . (...).*(S\d\dE\d\d).*(mp4) {0}-{1}{surfix}

test/ #重命名的结果如下:

| ----/abc-S01E01.mp4

|----/abc-S01E02.mp4

|----/abc-S01E03.mp4

|----/abc.txt #txt文件名保持不变

GNU LESSER GENERAL PUBLIC LICENSE Version 3, 29 June 2007 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. This version of the GNU Lesser General Public License incorporates the terms and conditions of version 3 of the GNU General Public License, supplemented by the additional permissions listed below. 0. Additional Definitions. As used herein, "this License" refers to version 3 of the GNU Lesser General Public License, and the "GNU GPL" refers to version 3 of the GNU General Public License. "The Library" refers to a covered work governed by this License, other than an Application or a Combined Work as defined below. An "Application" is any work that makes use of an interface provided by the Library, but which is not otherwise based on the Library. Defining a subclass of a class defined by the Library is deemed a mode of using an interface provided by the Library. A "Combined Work" is a work produced by combining or linking an Application with the Library. The particular version of the Library with which the Combined Work was made is also called the "Linked Version". The "Minimal Corresponding Source" for a Combined Work means the Corresponding Source for the Combined Work, excluding any source code for portions of the Combined Work that, considered in isolation, are based on the Application, and not on the Linked Version. The "Corresponding Application Code" for a Combined Work means the object code and/or source code for the Application, including any data and utility programs needed for reproducing the Combined Work from the Application, but excluding the System Libraries of the Combined Work. 1. Exception to Section 3 of the GNU GPL. You may convey a covered work under sections 3 and 4 of this License without being bound by section 3 of the GNU GPL. 2. Conveying Modified Versions. If you modify a copy of the Library, and, in your modifications, a facility refers to a function or data to be supplied by an Application that uses the facility (other than as an argument passed when the facility is invoked), then you may convey a copy of the modified version: a) under this License, provided that you make a good faith effort to ensure that, in the event an Application does not supply the function or data, the facility still operates, and performs whatever part of its purpose remains meaningful, or b) under the GNU GPL, with none of the additional permissions of this License applicable to that copy. 3. Object Code Incorporating Material from Library Header Files. The object code form of an Application may incorporate material from a header file that is part of the Library. You may convey such object code under terms of your choice, provided that, if the incorporated material is not limited to numerical parameters, data structure layouts and accessors, or small macros, inline functions and templates (ten or fewer lines in length), you do both of the following: a) Give prominent notice with each copy of the object code that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the object code with a copy of the GNU GPL and this license document. 4. Combined Works. You may convey a Combined Work under terms of your choice that, taken together, effectively do not restrict modification of the portions of the Library contained in the Combined Work and reverse engineering for debugging such modifications, if you also do each of the following: a) Give prominent notice with each copy of the Combined Work that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the Combined Work with a copy of the GNU GPL and this license document. c) For a Combined Work that displays copyright notices during execution, include the copyright notice for the Library among these notices, as well as a reference directing the user to the copies of the GNU GPL and this license document. d) Do one of the following: 0) Convey the Minimal Corresponding Source under the terms of this License, and the Corresponding Application Code in a form suitable for, and under terms that permit, the user to recombine or relink the Application with a modified version of the Linked Version to produce a modified Combined Work, in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source. 1) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (a) uses at run time a copy of the Library already present on the user's computer system, and (b) will operate properly with a modified version of the Library that is interface-compatible with the Linked Version. e) Provide Installation Information, but only if you would otherwise be required to provide such information under section 6 of the GNU GPL, and only to the extent that such information is necessary to install and execute a modified version of the Combined Work produced by recombining or relinking the Application with a modified version of the Linked Version. (If you use option 4d0, the Installation Information must accompany the Minimal Corresponding Source and Corresponding Application Code. If you use option 4d1, you must provide the Installation Information in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source.) 5. Combined Libraries. You may place library facilities that are a work based on the Library side by side in a single library together with other library facilities that are not Applications and are not covered by this License, and convey such a combined library under terms of your choice, if you do both of the following: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities, conveyed under the terms of this License. b) Give prominent notice with the combined library that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 6. Revised Versions of the GNU Lesser General Public License. The Free Software Foundation may publish revised and/or new versions of the GNU Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library as you received it specifies that a certain numbered version of the GNU Lesser General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that published version or of any later version published by the Free Software Foundation. If the Library as you received it does not specify a version number of the GNU Lesser General Public License, you may choose any version of the GNU Lesser General Public License ever published by the Free Software Foundation. If the Library as you received it specifies that a proxy can decide whether future versions of the GNU Lesser General Public License shall apply, that proxy's public statement of acceptance of any version is permanent authorization for you to choose that version for the Library.
