As Library

Example:

import fss.constants
import fss.config.log
import fss.orchestrator

root_path = '/etc'

filter_rules = [
    (fss.constants.FT_DIR, fss.constants.FILTER_INCLUDE, 'init'),
    (fss.constants.FT_FILE, fss.constants.FILTER_INCLUDE, 'net*'),
    (fss.constants.FT_FILE, fss.constants.FILTER_EXCLUDE, 'networking.conf'),
]

o = fss.orchestrator.Orchestrator(root_path, filter_rules)
for (entry_type, entry_filepath) in o.recurse():
    if entry_type == fss.constants.FT_DIR:
        print("Directory: [%s]" % (entry_filepath,))
    else: # entry_type == fss.constants.FT_FILE:
        print("File: [%s]" % (entry_filepath,))

Output:

Directory: [/etc/init]
File: [/etc/networks]
File: [/etc/netconfig]
File: [/etc/init/network-interface-container.conf]
File: [/etc/init/networking.conf]
File: [/etc/init/network-interface-security.conf]
File: [/etc/init/network-interface.conf]

Notice that even though we only include directories named “init” we’ll still see matching files from the root-path.

As Script

You can also use FSS from the command-line. You’ll get a printout of the results that you can consume and parse.

Example:

$ pathscan -i "i*.h" -id php /usr/include
F /usr/include/iconv.h
F /usr/include/ifaddrs.h
F /usr/include/inttypes.h
F /usr/include/iso646.h
D /usr/include/php
