ECHO(1V)  —  NEWS-OS Programmer’s Manual

NAME

echo − echo arguments

SYNOPSIS

echo [ −n ] [ arg ] ... 
/usr/5bin/echo [ arg ] ... 

DESCRIPTION

echo writes its arguments separated by blanks and terminated by a newline on the standard output.  If the flag −n is used, no newline is added to the output. 

/usr/5bin/echo (or echo built in /usr/5bin/sh) understands C-like escape conventions; beware of conflicts with the shell’s use of \:

\b backspace

\c print line without new-line

\f form-feed

\n new-line

\r carriage return

\t tab

\v vertical tab

\\ backslash

\n the 8-bit character whose ASCII code is the 1-, 2- or 3-digit octal number n, which must start with a zero.

echo is useful for producing diagnostics in shell programs and for writing constant data on pipes.  To send diagnostics to the standard error file, do ‘echo ... 1>&2’.
