Tmpf is tiny script (written in Ruby) to write standard output to a temporary file, run an application with the name of that file as an argument, then delete the temporary file when done. This is useful when you want to pipe output to a program that only accepts files, not standard input. Example: cat myfile.ps | tmpf gv (equivalent to: gv myfile.ps). Despite the incredible simplicity of this script, there is nothing quite like it provided among the standard Unix tools.
toast is a simple package manager for Unix. It automatically locates and downloads source code, determines how to compile it, installs each package in its own directory tree, and makes the resulting binaries available through an encap/GNU stow-like symlink tree. It also supports binary packages. It is often used to install and manage software in a non-root user's home directory.
toolwrap is a tool for managing package installation that extendes the functionality of Stow or Tinypackage. It makes it possible for different releases of a given application to coexist on a single workstation or be deployed on a file server. Policies files allow end-users to select which package is used when a tool is invoked from the command line.
tracx reads and stores any kind of XML data using a dedicated programming language. Read XML structure can be traced and changed. Unix Shell and JDBC database escapes allows you to retrieve data and store it into the XML structure. Implementations based on C++ and Java are available.
Trafmetux is a network traffic meter for Linux. It tells you how much IP traffic has been seen by the Linux kernel module during the last few minutes, hours, days, weeks, and months. It's very useful when you have a limited Internet connection with quotas. For instance, many mobile broadband ISP provide only 3GB/month. In that case, you need to know how many megabytes you already used.
trapdoor2 allows remote users to execute local commands by sending 'magic cookies'. this can e.g. be used to alter local firewalling rules so people can connect to local services after sending the magic cookie. trapdoor2 is implemented as a high-secure HTTPS server and includes support for the Wireless Application Protocol (WAP).
Treeps is program for Unix/Linux that is designed to make monitoring and interacting with the running programs on your system easy and intuitive. A "real time" tree view shows the relationships between the processes and is color-coded to provide easy interpretation of various values. The process tree displays any combination of users/groups and can be used to drill down into process details and then extract key fields for continuous monitoring. A number of actions can be performed on processes, such as signal, renice, trace, view man page, etc.
ttm is a simple but flexible command-line based Perl program for managing lists of tasks. Arbitrary properties can be attached to each task. Standard properties such as `priority', `status' and `categories' are used to provide different ways of viewing the task list. Editing is done with your favourite text editor.
