Free file deletion software for linux

File::Repl is a Perl module that provides file replication utilities.

SYNOPSIS

use File::Repl;

%con = {
dira => C:/perl,
dirb => M:/perl,
verbose => 1,
age => 10,
};

$ref=File::Repl->New(%con);
$r1 = $ref->Update(.p(l|m),ab,1);
$r2 = $ref->Update(.t.*,ab,1,.tmp$);

The File:Repl provides simple file replication and management utilities. Its main functions are

File Replication

Allowing two directory structures to be maintained, ensuring files that meet selection logic criteria are mirrored and otherwise synchronized.

Bulk Renaming

Allowing files in a directory structure to be renamed according to the selection logic.

Compressing

Allowing files in a directory structure to be compressed according to a given logic.

Process

Run a common perl process against files in a directory structure according to selection logic.

Deletion

Allowing files in a directory structure to be deleted according to the selection logic.

THC-SecureDelete is the best secure data deletion toolkit! If you overwrite a file for 10+ times, it can still be recovered. Read why and use the programs included (w/src!).

These tools can wipe files, free disk space, swap and memory! Changes: Linux LKM for secure file deletion included, small bufixes.

COMMANDLINE OPTIONS

Here are the commandline options:

srm [-d] [-f] [-l] [-l] [-v] [-z] file [file] [another file] [etc.]
sfill [-i] [-I] [-f] [-l] [-l] [-v] [-z] target-directory
sswap [-f] [-l] [-l] [-v] [-z] /dev/of_swap_filesystem
smem [-f] [-l] [-l] [-v]

The -s options are depricated now, and will be ignored.

-d dont delete the dot special files "." and ".." on the
commandline (only srm)
-i wipe only free inode space, not free disk space on the filesystem
(only sfill)
-I wipe only free disk space, not free inode space on the filesystem
(only sfill)
-f fast writes without O_SYNC and sync() between writes. Much faster
but less secure.
-l lessens the security. Only one random plus one pass with 0xff are
written.
-l a seconds time as parameter switches into the insecurest mode,
it overwrites the file only once with 0xff.
-v turn verbose mode on.
-z last wipe mode writes zeros instead of random data
file file to delete. Wildcards are of course allowed.
For unix: you need write permissions. For msdos: It may be hidden,
system, readonly etc. we dont care.
target-directory target is a directory in the filesystem to write to.
swap_filesystem your swap filesystem. Unmount it first!!
only tested on linux

Options may be applied like "-lfv", "-l -f -v" or a mix.

Note: If you use a gnu-compactible linux, you can use the patch rm.diff included in the package to put the features from srm into your normal rm. Just enter your fileutils-3.16 directory, type "patch < rm.diff" and then "make". You need at least one -s switch to activate (1 overwrite). Note that -sss is needed for full security.

NOTE:

For the linux kernel module, you just have to do "insmod sdel-mod" to load the module. After that, all files, which are deleted by any program are then wiped once before the space is marked as free.

File::Path is a Perl module to create or remove directory trees.

SYNOPSIS

use File::Path;

mkpath([/foo/bar/baz, blurfl/quux], 1, 0711);
rmtree([foo/bar/baz, blurfl/quux], 1, 1);

The mkpath function provides a convenient way to create directories, even if your mkdir kernel call wont create more than one level of directory at a time. mkpath takes three arguments:

the name of the path to create, or a reference to a list of paths to create,
a boolean value, which if TRUE will cause mkpath to print the name of each directory as it is created (defaults to FALSE), and
the numeric mode to use when creating the directories (defaults to 0777), to be modified by the current umask.
It returns a list of all directories (including intermediates, determined using the Unix / separator) created.
If a system error prevents a directory from being created, then the mkpath function throws a fatal error with Carp::croak. This error can be trapped with an eval block:

eval { mkpath($dir) };
if ($@) {
print "Couldnt create $dir: $@";
}

Similarly, the rmtree function provides a convenient way to delete a subtree from the directory structure, much like the Unix command rm -r. rmtree takes three arguments:

the root of the subtree to delete, or a reference to a list of roots. All of the files and directories below each root, as well as the roots themselves, will be deleted.
a boolean value, which if TRUE will cause rmtree to print a message each time it examines a file, giving the name of the file, and indicating whether its using rmdir or unlink to remove it, or that its skipping it. (defaults to FALSE)
a boolean value, which if TRUE will cause rmtree to skip any files to which you do not have delete access (if running under VMS) or write access (if running under another OS). This will change in the future when a criterion for delete permission under OSs other than VMS is settled. (defaults to FALSE)
It returns the number of files successfully deleted. Symlinks are simply deleted and not followed.

NOTE: There are race conditions internal to the implementation of rmtree making it unsafe to use on directory trees which may be altered or moved while rmtree is running, and in particular on any directory trees with any path components or subdirectories potentially writable by untrusted users.

Additionally, if the third parameter is not TRUE and rmtree is interrupted, it may leave files and directories with permissions altered to allow deletion (and older versions of this module would even set files and directories to world-read/writable!)

Note also that the occurrence of errors in rmtree can be determined only by trapping diagnostic messages using $SIG{__WARN__}; it is not apparent from the return value.

QDevelop project is a development environment entirely dedicated to Qt4.
QDevelop requires Qt4, gcc under Linux or MinGW under Windows, possibly gdb for programs debugging and ctags for code completion.
QDevelop is available in English, French, German, Dutch, Polish, Spanish, Chinese, Russian and Italian. If you want to translate in your language, please contact me.
QDevelop is not a Kdevelop like or reduced. Its an independent IDE dedicated to Qt and is totally independent of KDevelop. Less complete, but faster, light and especially multi-platforms. QDevelop and KDevelop have different code sources.
Main features:
- Cross Platform: Supports Linux, Windows 2000/XP/Vista, Mac OS X and FreeBSD
- Reading and writing project files (with some small restrictions)
- Add / Delete and edit project files (or external files)
- Management of normal projects and project SUBDIRS.
- Independent build for each projects. I.e. are rebuild only the really modified projects.
- A powerful editor with code completion, syntax highligthing, bookmarks, auto-brackets, auto-indentation, auto-save before build, line numbers and selection margin.
- A class browser who allows the programmer to browse, navigate, or visualize the structure of classes, members and functions of projects.
- In the event of errors or warnings of compilation, double-click on the line opens the corresponding editor.
- Debugging with gdb. Toggle breakpoints by click in the line number on editor or by right click. When the program is stopped on breakpoint, the local variables are automatically showed on output dock.
- In the editor, F1 call Assistant to show help for the word under the cursor.
- Open Source
- Its Free!
Enhancements:
Name:
- QIde becomes QDevelop at October 4, 2006
Corrections:
- A crash if a file is opened without project
- Bug in classes explorer when a sub-project have a name identical of the main project.
- Deletion of Auto-Hide docks, not working with Qt 4.2
- The settings are now written in qdevelop.ini file in the user home directory.
- The database of project is named "qdevelop-settings.db" in project directory.

- Add Bookmarks toolbar.
- Save bookmarks and breakpoints in project settings
- Add "console" to CONFIG variable in (.pro) file for new projects to have qDebug() written on debug console under Windows.
- Modification of the class browser to understand functions overloading.
- When a project is closed, the content of class browser is saved in database project.db. With this database, the content is reloaded very quickly during the loading of the project. This feature require to have the SQL driver sqlite enable. On build enter the option -qt-sql-sqlite after the configure command.
- Moving tabs with mouse to switch between us
- Detection when a file was modified by another program and ask for save or reload.
- Two tabs to show debugged variables program. Deletion of line edit "Debug command", obsolete with new tabs.
- Templates to create a project (based on dialog or main window).
- The code completion list contains the name and signature of functions.
- Entries "Close Other Tabs" and "Close All Tabs" in popup menu showed by right-click on editor Tab.

- The application can be build using cmake (experimental!)

DupeFinder is a simple application for locating, renaming, moving and deleting duplicate files in a directory structure.
Its perfect both for users who havent kept their hard drives very well organized and need to do some cleaning to free space, and for users who like to keep lots of backup copies of important data "just in case" something bad should happen.
Main features:
Although DupeFinder is a quite small application, it should have all of the features you will need to remove and reorganize large directories full of duplicate files:
- Well designed graphical interface with full tooltip and "Whats This?" question button support, useful in an application which you probably wont need to use frequently
- Quick processing by eliminating analysis of unwanted data through file extension filtering
- View files in external applications by double-clicking
- Rename files in place or move to new locations
- Default settings disallow deletion of all copies of duplicate files to prevent accidental data loss
- Generate simple reports identifying groups of duplicate files for later processing
While everything works pretty well in most cases, there are a few issues with DupeFinder to be aware of. I hope to fix most of the following bugs sometime soon:
- May crash if files containing "~" or ":" characters are encountered
- May crash if self referencing symlinks are encountered
- Zero byte files cannot be deleted
- May not be able to delete files with Unicode characters in filename
- Display does not update if identified duplicates are moved, renamed or modified external to DupeFinder

phpCodeCabinet provides an extensive, multi-platform code snippet library for any programming language.
phpCodeCabinet allows developers to store code snippets from any language. Features include user-defined categories, syntax highlighting, an extensive search engine, a theme-based interface, user authentication, and code/category ownership privileges.
Enhancements:
- Fixed bug in snippet.php and input.php that stripped slashes from snippet if magic_quotes_gpc was enabled in the php.ini.
- Added another link for "ENTER CODE" in the category bar below the snippet listings. (Just to make it easier to find.)
- Added option in config.php to specify allowable html tags for form fields other than the actual snippet (which allows all html tags by default).
- Modified search.php to include author name/email and language when searching. Now also presents snippet category with search results.
- Fixed bug in category deletion that leaves subcategories and snippets orphaned. Category deletion is now recursive in deleting subcategories and snippets, provided user is either an admin or owns all subordinate items.
- Fixed http script injection vulnerability within several files. Thanks to Yao-Wen (Wayne) Huang for pointing them out.
- Tabs are now preserved within code snippets.
- Added functionality for importing / exportingcategories and snippets. Currently exports in CSV format.
