apt

apt, short for Advanced Package Tool, is a package management system commonly used in Debian-based Linux distributions like Ubuntu. It simplifies the process of installing, updating, and managing software packages on a system.

Usually, we could do apt insatll or sudo apt install. In this case, commands would link into /usr/bin or /usr/local/bin which requires root permission. You could also use it to down load the deb file and download in local. Take a common software tree as an example:

apt download tree
dpkg -x tree_2.1.1-2ubuntu3_amd64.deb tree

After that, you just need to export the bin from tree into the environment.

wget

wget -c ulr
