linux下搜索文件的python方法，linuxpython,linux下如何用pyt

linux下如何用python方法来搜索文件，看看我写的方法是否可行。新手练习，多多指教！

python fsearch.py <file_pattern> [-p] 'path1 path2 path3'

os、sys、glob、re是代码中需要用到的几个方法

如果加-p选项则为指定目录查找
如果在-p选项添加完后跟一个-d选项则为深度查找

#!/usr/bin/env pythonimport os, sys, glob, reif sys.hexversion < 0x02040000:        print >> sys.stderr, 'Your python version is too old (%s)' % \                                                        (sys.version.split()[0])        print >> sys.stderr, 'You need at least Python 2.4'        sys.exit(1)PPATH = Falsedef search_all_files(pattern, search_path, pathsep=os.pathsep):    for path in search_path.split(pathsep):        '''        candidate = os.path.join(path, filename)        if os.path.isfile(candidate):            return os.path.abspath(candidate)        '''        for match in glob.glob(os.path.join(path, pattern)):            yield matchdef print_file(pattern, path=None):    if PPATH:p = path.split(' ')path = lambda p : os.pathsep.join(p)matches = list(search_all_files(pattern, path(p)))if matches:            for match in matches:                print match        else:print "Not find like '%s' !" % patternsys.exit(1)    else:       matches = list(search_all_files(pattern, os.environ['PATH']))if matches:    for match in matches:print matchelse:    print "Not find like '%s' !" % pattern    sys.exit(1)def deep_search(fpattern, path):pathlist = path.split(' ')finded = Falsefor p in pathlist:if os.path.exists(p):for dirpath, dirnames, filenames in os.walk(p):for file in filenames:fullpath = os.path.join(dirpath, file)if re.search(fpattern, fullpath):print fullpathfinded = Trueelse:continueelse:print "[*]Path %s don't exit !" % psys.exit(1)if not finded:print "Don't find like %s !" % fpatternif __name__ == '__main__':    if '-p' in sys.argv:PPATH = Trueif '-d' not in sys.argv:if len(sys.argv) != 4 or sys.argv[1].startswith('-'):    print "Usage %s <pattern> -p 'path1 path2 path3....' use escape to split pathname" % sys.argv[0]else:    print_file(sys.argv[1], sys.argv[3])elif sys.argv[4] == '-d':deep_search(sys.argv[1], sys.argv[3])    else:if len(sys.argv) != 2 or sys.argv[1].startswith('-'):print "Usage %s <pattern> " % sys.argv[0]sys.exit(1)        else:            print_file(sys.argv[1])
