wireshark recently. I have no idea in which directory it was installed, but it's not in
How do I find where it's installed?
Assuming you installed it from the repos:
$ dpkg -L wireshark wireshark-common /. /usr /usr/bin /usr/bin/wireshark /usr/share /usr/share/menu /usr/share/menu/wireshark /usr/share/pixmaps /usr/share/pixmaps/wsicon32.xpm /usr/share/applications /usr/share/applications/wireshark.desktop /usr/share/doc /usr/share/doc/wireshark /usr/share/doc/wireshark/copyright /usr/share/icons /usr/share/icons/hicolor /usr/share/icons/hicolor/48x48 /usr/share/icons/hicolor/48x48/apps /usr/share/icons/hicolor/48x48/apps/wireshark.png /usr/share/icons/hicolor/scalable /usr/share/icons/hicolor/scalable/apps /usr/share/icons/hicolor/scalable/apps/wireshark.svg /usr/share/man /usr/share/man/man1 /usr/share/man/man1/wireshark.1.gz /usr/share/doc/wireshark/changelog.Debian.gz /usr/share/doc/wireshark/README.Debian /. /usr /usr/bin /usr/bin/editcap /usr/bin/text2pcap /usr/bin/dumpcap /usr/bin/rawshark /usr/bin/mergecap /usr/bin/capinfos /usr/share /usr/share/doc /usr/share/doc/wireshark-common /usr/share/doc/wireshark-common/README.Debian /usr/share/doc/wireshark-common/copyright /usr/share/lintian /usr/share/lintian/overrides /usr/share/lintian/overrides/wireshark-common /usr/share/man /usr/share/man/man4 /usr/share/man/man4/wireshark-filter.4.gz /usr/share/man/man1 /usr/share/man/man1/mergecap.1.gz /usr/share/man/man1/capinfos.1.gz /usr/share/man/man1/dumpcap.1.gz /usr/share/man/man1/editcap.1.gz /usr/share/man/man1/text2pcap.1.gz /usr/share/man/man1/rawshark.1.gz /usr/share/doc/wireshark-common/changelog.Debian.gz
which wireshark will lead you to the executable. The output could ressemble this :
$ which wireshark /usr/bin/wireshark

I would recommend going with @Oli's answer, if that works for you. For applications that you (for whatever reason) didn't install with the
You can examine the unity launcher icon, it may be able to tell you:
The launcher file will usually be located in
/usr/share/applications/, and named something like
my-application-launcher.desktop. If you don't know exactly what the file is called, use
ls to examine the directory. (For your specific one, it is called
Once you know which one it is, examine its contents (anything from

gksu gksu gedit, not
The file will contain an entry with something like
Exec=/path/to/script.sh. If it only has a command, you can use
locate (like @Rinzwind said) to get the full path for it. Another option is to use
whereis to find the binary or source location.
The directory containing the launcher's target should be the installation directory for the program. If the launcher points to a shell script, sometimes examining its contents can reveal additional locations, if needed.
gksu nautilus when you get there will give you a windowed file browser with root permissions, meaning you can use it to copy/delete/edit any file, since normally installations are protected and will prevent you from modifying files as a normal user.
If that doesn't work, another option is to use
find, to find anything with the same name, or
grep, to find files containing the name.
However, you should only do this if you don't have any better alternatives. This can be a slow, tedious, mind-numbing process, especially since sometimes there is more than one location that stuff is installed to. If you can, use some other method.
if nothing of the above works try
locate. To do a
