If you have ever found yourself in the situation of needing to perform an action in Linux, but you are not sure which console command you may need there is a way you can find that command.
man -k are the command that will come to rescue you.
The way you can use the is.
Where copy is the action you want to perform, the output will be something like this.
cp (1) - copy files and directories cpgr (8) - copy with locking the given file to the password or group file cpio (1) - copy files to and from archives cppw (8) - copy with locking the given file to the password or group file dd (1) - convert and copy a file debconf-copydb (1) - copy a debconf database install (1) - copy files and set attributes mcopy (1) - copy MSDOS files to/from Unix objcopy (1) - copy and translate object files rcp (1) - secure copy (remote file copy program) scp (1) - secure copy (remote file copy program) ssh-copy-id (1) - install your public key in a remote machine's authorized_keys
As you can see it shows you a set of command that copies something, so you now only need to pick up the right one for your task.
You will have the same result using man -k, actually apropos is a synonym of man -k.
