\echo text [ ... ]

Prints the evaluated arguments to standard output, separated by spaces and followed by a newline. This can be useful to intersperse information in the output of scripts. For example:

=> \echo `date`
Tue Oct 26 21:40:57 CEST 1999

If the first argument is an unquoted -n the trailing newline is not written (nor is the first argument).

Tip

If you use the \o command to redirect your query output you might wish to use \qecho instead of this command. See also \warn.
