Usage

#Script

You can write a script for your shell demo. It can be started with run_demo.sh <FILE>.

#Syntax of scripts

• It is close to a shell script - with a limitiation of commands in a single line.
• Lines with starting # are comments and will be ignored.
• Leading whitespace will be ignored
• Additional commands:
  • cdm. prefix is detected - these function will be executed directly without prompt
  • rem [TEXT] is a shortcut for cdm.rem [TEXT]

But in short: for a first start write your commands line by line.

#Examples

#Basic example

# --------------------------------------------------
# example cdm script
# --------------------------------------------------
  
  rem ""
  rem "I am a remark."
  rem "and can display infos and hints."
  rem ""

  ls -ld /tmp
  uptime

# --------------------------------------------------

#Override the prompt

By default the prompt is set to user@tux-client (path) > - so your own user or hostname is not shown.

If you want to update it just to see something else or to simulate a remote session you can do it with these commands:

• cdm.setuser <username>
• cdm.sethost <host>

These commmands will be executed silently.

The path is the current directory which can change with cd <path> during your script.

• cdm.setpath <path>

You can set a fixed path value - but then keep in mind to update it again when you change directories.

# --------------------------------------------------

  cdm.shell "cd"

  rem ""
  rem "Have a look to the default prompt:"
  rem ""

  echo "That is the default prompt"

  rem "Now I set another user"
  cdm.setuser "anna"

  echo "I updated the user in the prompt"

  rem "Now I set another host"
  cdm.sethost "webserver-01"

  echo "I updated the host in the prompt"
