yes, if they're set up to make shotcuts there....if not, then just find them
usually they reside in /usr/bin or /bin or in other bin-directory, so that you can run them just by writing the executable's name in terminal (no path needed). or just write the beginning (like "kaz" without quotes) and press TAB so the rest of the name is displayed or then the names that equal the beginning.
if you wish to see where they are, do either
where "command" is the name of the executable. for the locate-command you need to do "updatedb" after installation if it's not done, so that it finds the file. whereis finds it if it's in some bin-directory.
