I wanted to install polybar-themes and one of the dependencies was networkmanager_dmenu so, i want to install it. Im on Ubuntu 20.04 and only valid option there for me is: Copy script somewhere into $PATH I have no idea on how to implement this, can someone explain this to me?
PATH is an environmental variable that contains a list of directories where the system searches for an executable that matched a command. See here for more information. The contents can be seen in your terminal with the command
echo $PATH
In theory, you thus could have your install program look at the directories in there, and install it in one of the directories listed.
However, there are conventions on the use of directories. sbins directories are intended for system binaries, bin directories for all other executables. You thus will select a bin directory:
/usr/bin. For Ubuntu, this means your software is packaged as a .deb installation file./usr/local/bin. That directory is not managed by the packaging system of the operating system.
