PYF：程序员的发现
pyf-programmers-find的Python项目详细描述
它的发音是“pif”。
pyf [options][search-pattern [filename-pattern [start-directory]]]
递归搜索其内容与搜索模式匹配的文件。
- （可选）将搜索限制为名称匹配的文件 文件名模式。
- （可选）chdir在开始搜索之前启动目录。
- 模式是python正则表达式。
因为我厌倦了写作而写作：
find . -name '*.py' -exec egrep -l regex {}\;
上面的PYF是：
pyf regex '\.py$'或
pyf regex 'py$'或者只是
pyf regex py
如果不将regex作为文件名模式传入，pyf假定它是 文件扩展名匹配，并在末尾添加$。
文件名模式和文件内部的搜索模式都是 Python regular expressions。
示例
查找包含regex
的文件pyf regex
上面的示例将递归地查找文件并在 文件。
将搜索限制为某些文件扩展名
pyf regex py
上面的示例将递归地查找名称以“py”结尾的文件 并在文件中搜索“regex”。
查找包含一个内容但不包含另一个内容的文件
pyf post html | pyf -v -f - csrf_token
上面查找名称以“html”结尾并包含“post”但 不包含“csrf\u令牌”。
在匹配的文件上运行命令
pyf -r "sed -i '' -e 's/yajogo\.core\.debug/yajogo.core.logging/g'"'yajogo\.core\.debug' py
上面查找扩展名为“py”且包含字符串的文件 “yajogo.core.debug”并对其运行sed命令。
打印regex匹配项
pyf -s -m '\d+x\d+' html
上面将在其名称为的文件中打印模式“+x+”的所有匹配项 以“html”结尾。-s选项禁止打印 比赛。m选项将导致打印匹配的正则表达式。所以， 使用上面的命令，您可能会得到如下输出：
57x57 72x72 114x114 512x512 200x200 150x150 150x150 150x150 500x500 800x600 150x150 150x150
我们可以把这个命令的输出通过管道传送到另一个程序。为了 示例：
pyf -s -m html '(\d+x\d+)'| sort | uniq
会给我们一个排序的唯一匹配列表：
114x114 150x150 200x200 500x500 512x512 57x57 72x72 800x600
安装
pip install pyf-programmers-find
用法
$ pyf -h usage: pyf [options][search-pattern [filename-pattern [start-directory]]] pyf: programmers find Recursively search for files whose contents matches search-pattern. Optionally restrict the search to files whose name matches filename-pattern. Patterns are Python regular expressions. It's pronounced "pif". positional arguments: search-pattern Match this pattern in files. filename-pattern Only search files whose name matches this pattern. start-directory Change to this directory before findind and searching files. optional arguments: -h, --help show this help message and exit --version show program's version number and exit --debug Turn on debug logging. --debug-log FILE Save debug logging to FILE. -c COUNT, --context COUNT Show COUNT surrounding context lines of the matches. Only makes sense when printing matched lines with the -p option. Default 0. -d START_DIRECTORY, --chdir START_DIRECTORY Change to directory START_DIRECTORY before starting the search. Can also be given as the third positional argument. -e SEARCH_PATTERN, --regexp SEARCH_PATTERN Use SEARCH_PATTERN as the pattern to match in a file; use when defining patterns beginning with -. Can also be given as the first positional argument. -f FILE, --file FILE File to search for a match. Instead of recursively searching all files. Can be given multiple times. If argument is - reads a list of files to match from stdin. -i, --ignore-case Ignore case. Default False. -l, --line-number Print the matching line number. Default False. -m, --matches Print the matching regex group. Default False. -n FILENAME_PATTERN, --filename FILENAME_PATTERN Recursively find files whose name matches FILENAME_PATTERN. Only search in those files. Can also be given as the second positional argument. Default: .+ -p, --print-lines Print the matching line. Default False. -r CMD, --run CMD Run a program CMD for each matching file, passing the path name of the matching file as an argument. Ignored if the -p or -l options are given. -s, --no-filename Do not print the file name when printing matched lines. Only makes sense with the -p option. Default False. -v, --invert-match Invert the sense of the match. Print non-matching files and lines. Default False. -A, --suppress-file-access-errors Do not print file/directory access errors. -B, --no-binary-check Ignore (heuristic) binary file check, do not skip probably binary files. -N, --no-pager Do not pipe output to a pager when stdout it detected as a tty. --force-pager Always try to pipe output to a pager, do not check if stdout is a tty. Ignored when running with the -r option. --skip-dirs-pattern SKIP_DIRS_PATTERN Regex of directories to skip. Default '(^\..+|CVS|RCS|__pycache__)'. --skip-files-pattern SKIP_FILES_PATTERN Regex of files to skip. Default '(^\..+|\.pyc$)'.
