Description

The eset command is used to edit environment variable values. For each
variable name given as an argument the eset command displays the variable
name and its value. and then allows you to edit it using the same line-editing
facilities available in the sh command, as described on page X??X. When you
press carriage-retur n, the new value is stored.

When using this command you should not place quotation marks around a
multiple-word value; otherwise the quotation marks will be stored with the
variable, which is probably not what you want.

See also the set and unset commands, on pages X??X and X??X respectively.
