Profiling utilities for Linux
This is a set of profiling utilities, currently targeting only Linux. It includes a simple command line profiling tool, with the following characteristics: * It is intended to be easy to install and use. No kernel modules or changes are required for basic use. It can be used without root access. * It supports profiling of dynamically linked code and includes information on time spent in dynamic libraries. * It supports profiling of multithreaded applications. * It generates profiles for all subprocesses started from a shell. Thus it easily can be used to profile application with multiple processes. * It tries to generate symbolic output. This is usually successful for the main program, if that has debug information, i.e. was compiled with -g. If not, you may need a debugger to fully interpret the results. However the raw output will often give you a rough idea of where processor time is spent. * It currently generates "flat" profiles. The output tells you roughly how much time was spent in a given instruction, line, or function f. By default this does not include time spent in functions called by f, but on platforms supported by libunwind a possible alternative is to include callees in profile counts, thus recovering some gprof-like functionality. * Linux kernel functions are not profiled separately. By default, time spent in the kernel is credited to the library function which made the kernel call. * On Itanium, it can be used to generate hardware-event-based profiles. For example, it can tell you where most of the cache misses occur.
More information about apt-get remove
Advanced Package Tool, or APT, is a free software user interface that works with core libraries to handle the installation and removal of software on Debian, Ubuntu and other Linux distributions. APT simplifies the process of managing software on Unix-like computer systems by automating the retrieval, configuration and installation of software packages, either from precompiled files or by compiling source code.
apt-get is the command-line tool for handling packages, and may be considered the user's "back-end" to other tools using the APT library.
apt-get remove is identical to install except that packages are removed instead of installed. Note that removing a package leaves its configuration files on the system. If a plus sign is appended to the package name (with no intervening space), the identified package will be installed instead of removed.
