How could we identify the installation path of firefox.exe using java code.
accumulator = (accumulator) && (runCommand("C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe", "-P PAX-PROFILE-1 %s", "google"));
accumulator = (accumulator) && (runCommand("C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe", "-P PAX-PROFILE-2 %s", "google"));
accumulator = (accumulator) && (runCommand("C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe", "-P PAX-PROFILE-3 %s", "google"));
Here I am passing windows complete firefox.exe path.
Right now i am executing these command in Java, using
Process p = Runtime.getRuntime().exec(parts);
Is there any way through which we can identify the location of
firefox.exe
as per the operating system.
Since you tagged the question as 'unix', on a Unix / Linux / MacOSX system, you can do this from the command line using the which
command; eg
$ which firefox
/usr/bin/firefox
So, to do the same in Java, you can use a Process
to run that command, and read the output into a string. It is also possible to do the same thing by reading the $PATH
environment variable, splitting it, and checking each of the directories on the path to see if they contain a "firefox" executable. (You could probably do the same thing on Windows).
BTW, executables on Unix / Linux / MacOSX do not have a ".exe" file suffix. The ".exe" suffix is a Windows-ism.
This is not java-specific. On unix systems (and DOS shells) the general contract of locating an executable is as follows:
At least that's what's used on the CLI. Desktop environments may use separate application registries.
