Description
Examples
Usage Note
Localization
echo writes its arguments, specified with the argument argument, to standard
output. echo accepts these C-style escape sequences:
\a Bell
\b Backspace
\c Removes any following characters, including \n and \r.
\f Form feed
\n Newline
\r Carriage return
\t Horizontal tab
\v Vertical tab
\0num The byte with the numeric value specified by the zero to three-digit octal
num.
\– Backslash
echo follows the final argument with a newline unless it finds \c in the arguments.
Arguments are subject to standard argument manipulation.
echo in the tcsh shell
In the tcsh shell, echo writes each word to the shell’s standard output, separated by
spaces and terminated with a newline.
tcsh echo accepts these C-style escape sequences:
\a Bell
\b Backspace
\e Escape
\f Form feed
\n Newline
\r Carriage return
\t Horizontal tab
\v Vertical tab
\nnn The EBCDIC character corresponding to the octal number nnn
See “tcsh — Invoke a C shell” on page 626.
1. One important use of echo is to expand filenames on the command line, as in:
echo *.[ch]
This displays the names of all files with names ending in .c or .h—typically C
source and include (header) files. echo displays the names on a single line. If
there are no filenames in the working directory that end in .c or .h, echo simply
displays the string *.[ch].
2. echo is also convenient for passing small amounts of input to a filter or a file:
echo 'this is\nreal handy' > testfile
echo is a built-in shell command.
echo uses the following localization environment variables:
v LANG
v LC_ALL
