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.
trickle is a lightweight, portable, per-application bandwidth shaper. It works in collaboration, has peak detection, and does smoothing. trickle works entirely in userland and does not require root to run. It has been developed on OpenBSD and is known to run on Linux, FreeBSD, and Solaris.
tsf is a command line utility for creating timestamped copies of files. When invoked on a file, a copy of that file is created with a name made of the file name plus a timestamp. When invoked again on the same timestamp mark, a copy with a timestamp plus a sub-index is created, and so on. tsf provides an easy and quick way for creating timestamped copies of files before modifying them.
tsocks provides transparent network access through a SOCKS version 4 or 5 proxy (usually on a firewall). tsocks intercepts the calls applications make to create TCP connections and determines if they can be directly accessed or need the SOCKS server. If they need the SOCKS server they connection is negotiated with the server transparently to the application. This allows existing applications to use SOCKS without recompilation or modification. tsocks is a wrapper library for the libc connect() call.
ttyload is a tty-based utility for monitoring the load averages on a Unix system. It presents 3 graphs, one for each of the 3 common load average numbers (1min, 5min, 15min) that things like uptime normally show you. Each graph is in its own color, and if two or more of the graphs happen to intersect, then the color changes to reflect that.
txt2pdf PRO is a very flexible and powerfu program that converts files from text to PDF format. It extends txt2pdf with features such as the ability to add form feeds, to skip the first form feed, to set the top and left margins, to use images (JPEGs) in the background, and to create compressed PDFs.
tzls and tzx are commandline utilities for quickly unpacking or listing the contents of various types of common Unix archive files, which may be compressed in any of several ways. The supported compression types are bzip2, gzip, and compress. The supported archive types are tar, cpio, zip, rar, and arj. The tools are implemented as shell scripts, so no compilation is required.
