NAME

echo − echo arguments

SYNOPSIS

echo [-n] [ arg ] ... 

DESCRIPTION

The echo command writes its arguments separated by blanks and terminated by a new-line on the standard output. The -n option prints a line without the new-line; same as using the \c escape sequence. 

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

\0n where n is the 8-bit character whose ASCII code is the 1-, 2- or 3-digit octal number representing that character. 

The echo command is useful for producing diagnostics in command files and for sending known data into a pipe. 

SEE ALSO

sh(1). 

CAVEATS

When representing an 8-bit character by using the escape convention \0n, the n must always be preceded by the digit zero (0). 

For example, typing: echo ´WARNING:\07´ will print the phrase WARNING: and sound the “bell” on your terminal.  The use of single (or double) quotes (or two backslashes) is required to protect the “\” that precedes the “07”. 

For the octal equivalents of each character, see ascii(5) in the INTER­ACTIVE SDS Guide and Programmer’s Reference Manual.
