.Dd October 5, 2016 .Dt ECHO 1 .Os .Sh NAME .Nm echo .Nd write arguments to the standard output .Sh SYNOPSIS .Nm .Op Fl n .Op Ar string ... .Sh DESCRIPTION The .Nm utility writes any specified operands, separated by single blank
q Ql " " characters and followed by a newline
q Ql \en character, to the standard output.
p The following option is available: l -tag -width flag t Fl n Do not print the trailing newline character. .El
p The end-of-options marker .Fl Fl is not recognized and written literally.
p The newline may also be suppressed by appending .Ql \ec to the end of the string, as is done by iBCS2 compatible systems. Note that the .Fl n option as well as the effect of .Ql \ec are implementation-defined in .St -p1003.1-2001 as amended by Cor. 1-2002. For portability, .Nm should only be used if the first argument does not start with a hyphen
q Ql "-" and does not contain any backslashes
q Ql "\e" . If this is not sufficient, .Xr printf 1 should be used.
p Most shells provide a builtin .Nm command which tends to differ from this utility in the treatment of options and backslashes. Consult the .Xr builtin 1 manual page. .Sh EXIT STATUS .Ex -std .Sh SEE ALSO .Xr builtin 1 , .Xr csh 1 , .Xr printf 1 , .Xr sh 1 .Sh STANDARDS The .Nm utility conforms to .St -p1003.1-2001 as amended by Cor. 1-2002. .Sh HISTORY The .Nm command appeared in .At v2 .
