where is my installed program in ubuntu?
 

i install matlab software in ubuntu and now i don't find it, where is it?

How should we know? YOU installed it.

Did you install it via RPM? Build from source? Did you specify an alternate install directory? Install it system-wide or just for your user? You don't say, and we can't guess.

Try doing "find / -name matlab".

Just a guess since you're a newbie... have you tried opening a terminal and typing 'matlab' at the command line?

The normal place for User Programs is in /usr, but some systems will use /opt

I use /opt only for things that I install manually. When I use the package manager, I take the defaults.

TBone has the answer---the "find" command, but here's a tip:
Always search for something using wildcards and quotes---like so:

find <dirname> -name "*matlab*" ## this gets you any file or directory name containing "matlab". I'm fuzzy on why the quotes are needed--I just do it because it seems to work more consistently.

Wait a second.. wasn't there a command that can tell the path of a program..? I think i read that somewhere.. just can't remember..

You can also try
on a shell. Or run
and see if it is installed at all.

Arch Linux

You can use "which", if the executable is in one of the directories listed in your $PATH.

oh, now i remember. I thought which worked even if the executable wasn't in one of the path directories..

Without quotes, the shell expands *matlab* to either:

• all files in the current directory with "matlab" in the name
• or the literal string *matlab* if no such files exist.

It then passes the result to find. The latter is what you want, and you can force the shell not to expand the *'s by using quotes.

If the package is a Debian package, ( matlab_x.x.deb ) :

Get a file list ( from an already installed package )
with the command 'dpkg -L matlab'

If you have the package present : 'less <package>'

.....

of course rude.

Not at all - you didn't give much info in your OP and it wasn't clear if you were asking:
a) I just installed Matlab and can't start it because it doesn't appear in the Applications menu, or:
b) I just installed Matlab and want to know where in the filesystem the binaries and other files are located.

(a) is a perfectly plausible (and sensible) question for someone used to having all programs in the start menu a la Windows/Mac OS. I guessed that might be what you meant and tried to help out (calling someone a newbie is no insult - we've all been there, I've still got quite a few newbish tendencies myself).

Have you found it yet?
