Find system path linux

How to find the installation path for a software under linux?

Under linux, I launch a software by typing, e.g., fluidplot. How can I find the installation path for this software?

to see where it is executing from (if it’s in your $PATH). Or:

find / -name fluidpoint 2> /dev/null 

to look for a file named fluipoint and redirect errors on virtual filesystems.

Usually they are in /sbin , /usr/sbin , /usr/local/bin or ~ as a hidden directory.

NAME which - shows the full path of (shell) commands. SYNOPSIS which [options] [--] programname [. ] 

@Michael excellent to know. Because of your comment, I just discovered that newer versions of bash also do this. +1 to your comment.

The «Usually they are . » line is pretty disingenuous, additional software should be in /opt/* or /usr/local/bin . ~ is your home directory, I’m confused why you call it «hidden».

Sorry to be ambiguous, I mean ~/.dir . The hidden directory is below the home directory. And I completely forgot about /usr/local/bin dop.

If you use an RPM based distribution (CentOS, RHEL, SUSE, openSUSE) you can use rpm -ql

rpm -ql findutils /bin/find /usr/bin/find /usr/bin/xargs /usr/share/doc/packages/findutils /usr/share/doc/packages/findutils/AUTHORS /usr/share/doc/packages/findutils/COPYING /usr/share/doc/packages/findutils/NEWS /usr/share/doc/packages/findutils/README /usr/share/doc/packages/findutils/THANKS /usr/share/doc/packages/findutils/TODO /usr/share/info/find.info.gz /usr/share/man/man1/find.1.gz 

Things aren’t installed to locations in the Linux/UNIX world like they are in the Windows (and even somewhat in the Mac) world. They are more distributed. Binaries are in /bin or /sbin , libraries are in /lib , icons/graphics/docs are in /share, configuration is in /etc and program data is in /var .

The /bin , /lib , /sbin contain the core applications needed for booting and the /usr contains all the other user and system applications.

Just to add some point to @djsumdog’s answer, if you are using DPKG based dist, like Ubuntu, you can use

to check what it is about, and

dpkg --listfiles some_package 

to check what files are included/relevant to this package. It’s for packages that don’t have a binary to run, like libnss3 . And

to find what package includes this file.

For example, dpkg —listfiles libnss3 gives me:

/. /usr /usr/lib /usr/lib/i386-linux-gnu /usr/lib/i386-linux-gnu/libssl3.so /usr/lib/i386-linux-gnu/nss /usr/lib/i386-linux-gnu/nss/libsoftokn3.chk /usr/lib/i386-linux-gnu/nss/libnssckbi.so /usr/lib/i386-linux-gnu/nss/libnsssysinit.so /usr/lib/i386-linux-gnu/nss/libfreebl3.chk /usr/lib/i386-linux-gnu/nss/libnssdbm3.chk /usr/lib/i386-linux-gnu/nss/libnssdbm3.so /usr/lib/i386-linux-gnu/nss/libsoftokn3.so /usr/lib/i386-linux-gnu/nss/libfreebl3.so /usr/lib/i386-linux-gnu/libnssutil3.so /usr/lib/i386-linux-gnu/libsmime3.so /usr/lib/i386-linux-gnu/libnss3.so /usr/share /usr/share/doc /usr/share/doc/libnss3 /usr/share/doc/libnss3/copyright /usr/share/doc/libnss3/changelog.Debian.gz /usr/share/lintian /usr/share/lintian/overrides /usr/share/lintian/overrides/libnss3 

Note that the folders are not only owned by this packages, but by others too. Just check the files.

And reversely, dpkg —search libnss3.so gives me:

firefox: /usr/lib/firefox/libnss3.so thunderbird: /usr/lib/thunderbird/libnss3.so libnss3:i386: /usr/lib/i386-linux-gnu/libnss3.so libnss3-1d:i386: /usr/lib/i386-linux-gnu/libnss3.so.1d

services are automatically installed. How to find exact path where any service is installed and their configuration files??

3 Answers 3

There are quite a few ways to find this but I usually prefer following

and to find from which path program is using, I use

If you’re using apt-get , install apt-file program and you can list the contents of the package:

sudo apt-file update apt-file list package_name 

This will show all the files that will be installed by a package, binaries, configuration files, systemd startup files, etc.

If you use yum , install yum-utils and use repoquery :

Suppose service name is nginx then you can find it in /etc/nginx/ on ubuntu .

On centos you can check path using commands given by slashRahul. As per my knowledge you can not change installation path while installing by apt-get. Software components are not installed in a single directory, but across many folders like binaries stay in /usr/bin/, /bin, /sbin, Configuration in other directories.
