shtool-echo - GNU shtool echo(1) extensional command
shtool echo [-n|--newline] [-e|--expand] string
shtool echo is an echo(1) style command which prints string to stdout
and optionally provides special expansion constructs (terminal bold
mode, environment details, date, etc) and newline control. The trick of
this command is that it provides a portable -n option and hides the
gory details needed to find out the environment details under option
The following command line options are available.
By default, output is written to stdout followed by a "newline"
(ASCII character 0x0a). If option -n is used, this newline
character is omitted.
If option -e is used, string can contain special "%x" constructs
which are expanded before the output is written. Currently the
following constructs are recognized:
%B switch terminal mode to bold display mode.
%b switch terminal mode back to normal display mode.
%u the current user name.
%U the current user id (numerical).
%g the current group name.
%G the current group id (numerical).
%h the current hostname (without any domain extension).
%d the current domain name.
%D the current day of the month.
%M the current month (numerical).
%m the current month name.
%Y the current year.
