How to add shared libraries to Linux's system library path (.so)

Ubuntu

Create a new file in /etc/ld.so.conf.d/ called .conf Edit the file and add a line per directory of shared libraries (*.so files), it will look something like:

/usr/lib/APPLICATION/lib

Reload the list of system-wide library paths:

sudo ldconfig

Debian

Edit /etc/ld.so.conf Add a line per directory of shared libraries (*.so files) to the bottom of the file, it will look something like:

/usr/X11R6/lib
/usr/lib/APPLICATION/lib

Reload the list of system-wide library paths:

ldconfig

If you run your new application it should now work fine without you having to set any LD_LIBRARY_PATH environment variables. If you still have problems you can obtain a list of the libraries that are on the system path by re-running the ldconfig command in verbose mode:

ldconfig -v

Terminal

Copy/paste to clipboard

sudo apt install xclip

  • Create alias to commands inside .bashrc or .zshrc

alias tcopy="xclip -selection c"; 
alias tpaste="xclip -selection clipboard -o"

  • Example

echo -n test | tcopy

Install `.deb` files

sudo apt install gdebi
sudo gdebi deb-file.deb
