Free files software for linux

FileSystem Investigator is a platform independent file system viewer and data extraction tool. It allows the user to:

* View the contents of the target file system in a forensicly safe manner, bypassing the normal operating system mechanisms.
* Extract files and whole directory trees of files from the source filesystem.

Since it is written in platform-neutral Java, it can be used to examine filesystems outside their native environment. For example, it can be used to view a Linux filesystem while running under Windows.

FileSystem Investigator directly accesses the source disk and processes the data using it own built in filesystem drivers. This ensures that it is safe to use FileSystem Investigator for forensic investigations.

FileSystem Investigator will never write to the source media thus important timestamps are preserved. FileSystem Investigator can also read disk-image files such as those created by dd.

Files and whole directory structures can be extracted easily from the source drive and stored for further use or analysis. Due to limitations imposed by Java, special files such as device nodes, pipes, sockets and links, cannot be extracted.

The Apache::FileManager module is a simple HTML file manager. It provides file manipulations such as cut, copy, paste, delete, rename, extract archive, create directory, create file, edit file, and upload files.
It also has the ability to rsync the server htdocs tree to another server with the click of a button.
Enhancements:
- prevented file edit screen from opening when cancel is clicked when creating new filenames
- fixed up documentation

File Activity Viewer opens a file and shows you the last lines (this is configurable) and then keeps waiting for changes in that file.
It works like a graphical (with GUI) tail -f.
Enhancements:
- Add Edit menu with Copy, Clear and Select All functions.
- Add possibility to open multiple files at once in the same window

php file browser is a simple Web-based file browser.
php file browser allows the user to upload files, delete, copy, make directories and paste files and directories. It has two access levels: one for admin, one for guest.
Access for guests can be optionally password protected.
Enhancements:
- A PHP file source viewer was added.
- The directory lister now works much faster than in older versions.
- Big changes were made in the class files.

Tie::File can access the lines of a disk file via a Perl array.

SYNOPSIS

# This file documents Tie::File version 0.96
use Tie::File;

tie @array, Tie::File, filename or die ...;

$array[13] = blah; # line 13 of the file is now blah
print $array[42]; # display line 42 of the file

$n_recs = @array; # how many records are in the file?
$#array -= 2; # chop two records off the end


for (@array) {
s/PERL/Perl/g; # Replace PERL with Perl everywhere in the file
}

# These are just like regular push, pop, unshift, shift, and splice
# Except that they modify the file in the way you would expect

push @array, new recs...;
my $r1 = pop @array;
unshift @array, new recs...;
my $r2 = shift @array;
@old_recs = splice @array, 3, 7, new recs...;

untie @array; # all finished

Tie::File represents a regular text file as a Perl array. Each element in the array corresponds to a record in the file. The first line of the file is element 0 of the array; the second line is element 1, and so on.

The file is not loaded into memory, so this will work even for gigantic files. Changes to the array are reflected in the file immediately. Lazy people and beginners may now stop reading the manual.

Audio::File is a audio file abstraction library.

SYNOPSIS

use Audio::File;
my $file = Audio::File->new( "foo.bar" );

print "The ". $file->type() ."-file ". $file->name
." is ". int $file->length() ." seconds long.n";

print "Its interpreted by ". $file->tag->artist()
." and called ". $file->tag->title() ".n";

Audio::File abstracts a single audio file, independant of its format. Using this module you can access a files meta-info like title, album, etc. as well as the files audio-properties like its length and bitrate.

Currently only the formats flac, ogg vorbis and mp3 are supported, but support for other formats may be easily added.

Audio::TagLib::File is a file class with some useful methods for tag manipulation.

This class is a basic file class with some methods that are particularly useful for tag editors. It has methods to take advantage of ByteVector and a binary search method for finding patterns in a file.

DESTROY()

Destroys this File instance.

PV name()

Returns the file name in the local file system encoding.

Tag tag() [pure virtual]

Returns this files tag. This should be reimplemented in the concrete subclasses.

AudioProperties audioProperties() [pure virtual]

Returns this files audio properties. This should be reimplemented in the concrete subclasses. If no audio properties were read then this will return undef.

BOOL save() [pure virtual]

Save the file and its associated tags. This should be reimplemented in the concrete subclasses. Returns true if the save succeeds.

ByteVector readBlock(UV $length)

Reads a block of size $length at the current get pointer.

void writeBlock(ByteVector $data)

Attempts to write the block $data at the current get pointer. If the file is currently only opened read only -- i.e. readOnly() returns true -- this attempts to reopen the file in read/write mode.

IV find(ByteVector $pattern, IV $fromOffset = 0, ByteVector $before = ByteVector::null)

Returns the offset in the file that $pattern occurs at or -1 if it can not be found. If $before is set, the search will only continue until the pattern $before is found. This is useful for tagging purposes to search for a tag before the synch frame.

Searching starts at $fromOffset, which defaults to the beginning of the file.

This has the practial limitation that $pattern can not be longer than the buffer size used by readBlock(). Currently this is 1024 bytes.

IV rfind(ByteVector $pattern, IV $fromOffset = 0, ByteVector $before = ByteVector::null)

Returns the offset in the file that $pattern at or -1 if it can not be found. If $before is set, the search will only continue until the pattern $before is found. This is useful for tagging purposes to search for a tag before the synch frame.

Searching starts at $fromOffset and proceeds from the that point to the beginning of the file and defaults to the end of the file.

This has the practial limitation that $pattern can not be longer than the buffer size used by readBlock(). Currently this is 1024 bytes.

void insert(ByteVector $data, UV $start = 0, UV $replace = 0)

Insert $data at position $start in the file overwriting $replace bytes of the original content.

This method is slow since it requires rewriting all of the file after the insertion point.

void removeBlock(UV $start = 0, UV $length = 0)

Removes a block of the file starting a $start and continuing for $length bytes.
This method is slow since it involves rewriting all of the file after the removed portion.

BOOL readOnly()

Returns true if the file is read only (or if the file can not be opened).

BOOL isOpen()

Since the file can currently only be opened as an argument to the constructor (sort-of by design), this returns if that open succeeded.

BOOL isValid()

Returns true if the file is open and readble and valid information for the Tag and / or AudioProperties was found.

void seek(IV $offset, PV $p = "Beginning")

Move the I/O pointer to $offset in the file from position $p. This defaults to seeking from the beginning of the file.

void clear()

Reset the end-of-file and error flags on the file.

IV tell()

Returns the current offset withing the file.

IV length()

Returns the length of the file.

BOOL isReadable(PV $file) [static]

Returns true if $file can be opened for reading. If the file does not exist, this will return false.

BOOL isWritable(PV $file) [static]

Returns true if $file can be opened for writing.

%_Position

Position in the file used for seeking. C<<less
