tcar-hello(1) ======== Name ---- tcar-hello - Print out greetings and exit successfully. Synopsis -------- *centos-art tcar-hello [OPTIONS]* Description ----------- The *tcar-hello* module is very simple. Its main purpose is to print out the ``Hello, World!'' greeting to standard output and exit successfully. You can use options to change the greeting message and the way it is printed out. The *tcar-hello* module provides a very simple example you can use as base to understand how modules work inside *tcar.sh* script. You can this understanding to start writing your own modules for *tcar.sh* script. Options ------- The *tcar-hello* module accepts the following options: *-h | --help*:: Print out module's documentation. *-v | --version*:: Print out module's version and legal status. *-d | --debug*:: Run the script in debugging mode. This option is very useful if you want to get a closer look to module environments being executed and destroyed at run-time. *-g "TEXT" | --greeting="TEXT"*:: Set a different greeting message to be printed out. This option accepts a value as argument. The text you provide must not have empty spaces on it. By default, when you don't provide this option, *tcar-hello* module prints out ``Hello, World'' as greeting. If translations of this message are available for your locale, they will be printed instead. *-l | --lower*:: Print greeting message in lowercase. The final output is printed out all in one line. *-u | --upper*:: Print greeting message in uppercase. The final output is printed out all in one line. *-c | --camel*:: Print greeting messages in camel-case (e.g., "HeLlO, WoRlD!"). The output is printed out one character per line. This might not have sense but it helps to describe how execution of sibling modules work. Notice that, when printing final output, punctuation marks doesn't count for formating. *-r | --random*:: Print letters of a greeting message in a random order (e.g., rdodldrl!,,!). The final output is printed out one character per line. This might not have sense but it helps to describe how recursive execution of sibling modules work. Exit Status ----------- The *tcar-hello* module ends its execution with one of the following exit status: * 0 -- Exit successfully without errors. * 1 -- Exit with errors.
