SHTOOL-ECHO.TMP(1) GNU Portable Shell Tool SHTOOL-ECHO.TMP(1) NAME shtool echo - GNU shtool echo(1) extensional command SYNOPSIS shtool echo [-n|--newline] [-e|--expand] string DESCRIPTION shtool echo is an echo(1) style command which prints string to stdout and optionally provides special expansion constructs (terminal bold mode, envi- ronment 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 -e. OPTIONS The following command line options are available. -n, --newline By default, output is written to stdout followed by a "newline" (ASCII character 0x0a). If option -n is used, this newline character is omit- ted. -e, --expand If option -e is used, string can contain special "%x" constructs which are expanded before the output is written. Currently the following con- structs 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. EXAMPLE # shell script shtool echo -n -e "Enter your name [%B%u%b]: "; read name shtool echo -e "Your Email address might be %u@%h%d" shtool echo -e "The current date is %D-%m-%Y" HISTORY The GNU shtool echo command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 1998 for Website META Language (WML) under the name buildinfo. It was later taken over into GNU shtool.
