This means that your path has been extended with /usr/src/hive/build/dist/bin/ . Usually / usr / bin, / bin, / usr / sbin, etc. Are "on your way." If you have the / bin / sh program, you can simply type sh to run it. If you have a program in /usr/src/hive/build/dist/bin/appname , you can simply run appname to execute it.

export is a command in the Bash shell language. When used to set a variable, as in your example, the variable (PATH) will be visible ("exported to"), any running subprocesses from this Bash instance. Without the export command, the variable would not exist in the subprocess.

It sets the PATH environment variable to the value of any PATH currently plus the new path added to it.
