Linux application installation?
Unlike windows in linux files get put all over the place. For the most part they are installed in the usr directory. the execute file is stored in the bin or in /usr/sbin directories.





as for uninstalling them, that depends on how you installed it. if you used an rpm then it is easy, if you installed from source thats hard you just have to delete every file associated with the program. but with an rpm you can use the rpm command to remove the program. if you are using a installation program like yum or yast then you can remove it that way.

Reply:In linux you can install programs whereever you want.


It is completely under your control. If you like a


Windows style program directory, you can create one


and install all your programs there. Otherwise, you


can pick and choose where each program installs at the


time of installation. If a program is supposed to be


used by many (even all) users of the machine, it is


customary to put it in a directory, which is usually


included in everybody's environment variable PATH,


such as /usr, or /usr/local, /usr/bin, /usr/local/bin.


But doing so is not a requirement, it's a matter of taste.


(If you use c-shell or t-shell you can check your


PATH by typing 'printenv PATH' (without the quotes.)


You can also change it to be something else.)





There is one other big difference in program installation.


In Windows, the installed programs modify a very special


directory called "registry", which most users are not even


aware of. In linux, there is no registry at all. A


program does not have to register with OS in order to be


able to execute. This makes the process of installation


and uninstallation much simpler in Linux. You can simply


remove the executable and all the directories that


executable has modified (the directories where its files


and data resides) the program is gone! In windows, in


contrast, this does not remove the program, you also have


to clean up the registry, which is a mess.
