ECHO(1V) — USER COMMANDS
NAME
echo − echo arguments
SYNOPSIS
echo [ −n ] [ argument ... ]
SYSTEM V SYNOPSIS
echo argument ...
DESCRIPTION
echo writes its arguments on the standard output. Arguments must be separated by spaces or tabs, and terminated by a newline.
echo is useful for producing diagnostics in shell programs and for writing constant data on pipes. If you are using the Bourne Shell (sh(1)), you can send diagnostics to the standard error file by typing:
echo ... 1>&
SYSTEM V DESCRIPTION
Note:If /usr/5bin is ahead of /usr/bin in the Bourne shell’s search path, its built-in echo command mimics the System V version of echo as described here.
echo also 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.
OPTIONS
−nDon’t add the newline to the output.
