NAME
echo - produce message in a shell script
SYNOPSIS
echo [ -n | -e ] args...
DESCRIPTION
Echo prints its arguments on the standard output, separated
by spaces. Unless the -n option is present, a newline is
output following the arguments. The -e option causes echo
to treat the escape sequences specially, as described in the
following paragraph. Only one of the options -n and -e may
be given.
If any of the following sequences of characters is encoun-
tered during output, the sequence is not output. Instead,
the specified action is performed:
\b A backspace character is output.
\c Subsequent output is suppressed. This is normally used
at the end of the last argument to suppress the trail-
ing newline that echo would otherwise output.
\f Output a form feed.
\n Output a newline character.
\r Output a carriage return.
\t Output a (horizontal) tab character.
\v Output a vertical tab.
\0digits
Output the character whose value is given by zero to
three digits. If there are zero digits, a nul charac-
ter is output.
\\ Output a backslash.
HINTS
Remember that backslash is special to the shell and needs to
be escaped. To output a message to standard error, say
echo message >&2
BUGS
The octal character escape mechanism (\0digits) differs from
the C language mechanism.
