ftff - fault tolerant file find utility


ftff [-#fFhIpq][-t#][start_directory] file_to_find


ftff recursively descends the directory hierarchy and reports all objects in the file
system with a name that approximately matches the given filename.

ftff achieves fault tolerance by calculating the so called Weighted Levenshtein
Distance. The Levenshtein Distance is defined as the minimum number of character
insertions, deletions and replacements that transform a string A into a string B.

ftff behaves like

'find start_directory -name file_to_find -print'

with the following differences:

- ftff is fault tolerant

- ftff is NOT case sensitive

- the level of fault tolerance can be adjusted by specifying the optional parameter
tolerance. A tolerance of 0 specifies exact match.


-h Prints a little help/usage information.

-f Follow symbolic links on directories. Note: a symbolic link like "somewhere -> .."
causes naturally an endless loop. By default ftff does not follow symbolic links
to directories.

-F Classify the file type by appending a character to each file name. This character
'*' for regular files that are executable
'/' for directories
'@' for symbolic links
'|' for FIFOs
'=' for sockets

-p print the actual distance value in front of the filename. This value is equal to
the number of insertions, deletions and replacements necessary to transform the
file that was found into the search key (the file_to_find).

-q keep quiet and do not print any warning about non readable directories.

-# or -t#
Set the fault tolerance level to #. The fault tolerance level is an integer in the
range 0-255. It specifies the maximum number of errors permitted in finding the
approximate match. The default tolerance is (strlen(searchpattern) - number of
wildcards)/6 + 1

-I Do case sensitive search (default is case in-sensitive)

The filename to search for. '*' and '?' can be used as wildcards.
'?' denotes one single character.
'*' denotes an arbitrary number of characters.

The directory to start the search. The current directory is the default.

The last argument to ftff is not parsed for options as the program needs at least one
file-name argument. This means that ftff -x will not complain about a wrong option but
search for the file named -x.


ftff samething

This will e.g. find a file called something or sameting or sum-thing or ...

To find all files that start with any prefix, have something like IOComm in between and
end on a two letter suffix:

ftff '*iocomm.??'

To find all files that exactly start with the prefix DuPeg:

ftff -0 'dupeg*'
