The echo command echos a string to the terminal. One use for
this command is in determining the contents of environment variables.
Environment variables are variables that Unix keeps track of at the
shell level. Two common examples are TERM and PATH. The TERM variable
identifies what kind of terminal you are using. The PATH variable
contains a list of pathnames to search through when looking for commands.
More information on environment variables can be found in
the Login files section.
To see the contents of the TERM variable type echo $TERM.
