Where are the Programs in Ubuntu [duplicate]

I am new to ubuntu and linux world. Where can I see the list of all programs installed in ubuntu ? Ex: If I want to launch «terminal». I need to click the upper left icon and type «terminal». Where is the icon really located ? I would like to take a look in the programs installed. Are they separeted by category ? I don’t know. Thanks

@empedokles — no, in anything is a lot more organised than many other OSes. Felippe Leite, you can also open terminal by pressing ‘Ctrl’+’Alt’+’T’ by default — you can also add applications to the launcher/favourites/whatever.

The OP is not asking about where the programs are installed. He wants to see a list of all installed programs to find out what is installed. @BryceAtNetwork23 this is not a duplicate. Don’t close. Felippe Leite Please edit your question to clarify what you want to know. Otherwise your question will be closed.

If you are new to Ubuntu, you will probably not feel comfortable with scripts, but this might be interesting for you: askubuntu.com/a/490398/72216

Most of launchers for programs that appear in menus/launcher/dash can be found in /usr/share/applications :

the menu/dash program searches their for launchers. Each user can also have their own launchers in ~/.local/share/applications .

The actual files end with the .desktop extension, and have something like the following contents:

[Desktop Entry] Version=1.0 Name=Firefox GenericName=Web Browser Comment=Browse the Web Exec=firefox %u Icon=firefox Terminal=false Type=Application MimeType=text/html;text/xml;application/xhtml+xml;application/vnd.mozilla.xul+xml;text/mml;x-scheme-handler/http;x-scheme-handler/https; StartupNotify=true Categories=Network;WebBrowser; Keywords=web;browser;internet; X-Desktop-File-Install-Version=0.21 

Note the exec line indicated what command to execute (in /usr/bin or somewhere else in the user’s $PATH ) — other information is also included, such as the icon to use (by default from /usr/share/icons , also from ~/.local/share/icons ), name, category, etc.

Launchers can also be hidden using NoDisplay / Hidden , mutiple version can also be in place, each with different configuration (e.g. the three Banshee launchers above)

You can also create your own launchers, and read the specification of .desktop files here

How do I list all installed programs?

Hm, I’m interested in Red Hat, Ubuntu, and cygwin. Is there a distribution-free way to list the programs with some command line argument?

4 Answers 4

That depends on your distribution.

• Aptitude-based distributions (Ubuntu, Debian, etc): dpkg -l
• RPM-based distributions (Fedora, RHEL, etc): rpm -qa
• pkg*-based distributions (OpenBSD, FreeBSD, etc): pkg_info
• Portage-based distributions (Gentoo, etc): equery list or eix -I
• pacman-based distributions (Arch Linux, etc): pacman -Q
• Cygwin: cygcheck —check-setup —dump-only *
• Slackware: slapt-get —installed

All of these will list the packages rather than the programs however. If you truly want to list the programs, you probably want to list the executables in your $PATH , which can be done like so using bash’s compgen :

Or, if you don’t have compgen :

#!/bin/bash IFS=: read -ra dirs_in_path "; do for file in "$dir"/*; do [[ -x $file && -f $file ]] && printf '%s\n' "$" done done 

It would be better to distinguish between package managers instead of «distributions». NetBSD’s pkgsrc runs on any Linux, and some package managers can be used on multiple Uinces.

Answering the second part of the question (nothing really to be added to Chris’ answer for the first part):

There is generally no way of listing manually installed programs and their components. This is not recorded anywhere if you didn’t use a package manager. All you can do is find the binaries in standard locations (like Chris suggested) and in a similar way, guess where some libraries or some manual pages etc. came from. That is why, whenever possible, you should always install programs using your package manager.

Programs should be reachable via the PATH, so just list everything in the path:

Expect a result of about 3k-4k programs.

To exclude a probable minority of false positives, you may refine the approach:

for d in $ ; do for f in $d/* ; do test -x $f && test -f $f && echo $f done done 

It didn’t make a difference for me.
