Some Linux command that you can use it in termux emulater this command can be used for every Linux distribution.
cd command
Cd [directory name] use this command to move from local directory to next/previous directory
For examples : if you are in a directory called "local _directory" contain other directories one of them named "next_directory", to move from "local_directory " to " next_directory" just type :
cd next_directory then hit enter, if next_directory contain an other directory jus type cd directory_name , in case you want to return to previous folder in this case you don't have to know the name of the file just type cd .. (cd space then 2 point) then hit enter.
