有一个小众的需求: 创建大量的某种特性的文件, 用于测试程序.
个人实现了一个简单的程序, cttfiles, 可以:
-
设置目录和文件的数量, 目录层级;
-
设置文件的内容来源为其他文件, 目录或随机生成;
-
设置文件的大小范围;
-
设置文件名和目录名的生成规则;
使用说明如下
Usage:
cttfiles.py [options] directory
Options:
-d create directories, default false, Create directories recursivly,
depth of directry is set by argument 'depth'.
-f create files, default true
-h show help message
-m mix mode, default false. Create directories recursivly, then create files in each directory.
Directory
--depth=DEPTH directory depth, default 1
--dnum=DNUM num of directories, default 10
--dprefix=DPRE prefix of directory name
--dsuffix=DSUF suffix of directory name
File
--exts=EXTS file extensions, separated by ','
--from_dirs=DIRECTORIES A test file's content is one of file in DIRECTORIES, which is randomly selected.
--from_files=FILES A test file's content is one of FILES, which is randomly selected.
--fprefix=FPRE prefix of file name
--fsuffix=FSUF suffix of file name
--fnum=FNUM num of files, default 10
--fminsize=FMINSIZE min size of file when file's content is created randomly. default 1.
--fmaxsize=FMAXSIZE max size of file when file's content is created randomly. default 1024.
示例:
$ python cttfiles.py -m --depth=2 --dnum=3 --dprefix='dp' --dsuffix='ds' --exts='php,jsp' --from_files="1.jsp,1.php" --fprefix="fp" --fsuffix="fs" --fnum=2 tmp_dir
