.TH ECHO 1 "15 April 1985" .SH NAME echo \- echo arguments .SH SYNOPSIS .B echo [ .B \-nqr ] [ arg ] ... .SH DESCRIPTION .I Echo writes its arguments separated by blanks and terminated by a newline on the standard output. If the flag .B \-n is used, no newline is added to the output. If the flag .B \-q is used, the .I echo runs quietly (arguments are not echoed). .B \-r is used to echo arguments randomly. .PP .I 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'. .I Echo with the .B \-q or .B \-r option is not useful.
