Linux shell scripting

So you can re-script the Linux shell to act more like ms-dos. The DOS command CLS in ubuntu linux is clear. so you can create a short bash shell script and this is the example:

open a new shell with the command "konsole --type us" ...
then type the next commands,
1. cd /bin
2. vi cls
OK, so now you have opened a new file to be scripted called "cls". Next we have to use the shell text editor "VI".

type in the script:
#!/bin/sh
clear

it's just 2 lines of text.

To Setup the script to execute as a command you change the permissions:
1. chmod 555 cls and/or chmod 255 cls
(gives everyone read/execute permission)
and/or
2. chmod +rx cls
(gives everyone read/execute permission)
3. chmod u+rx cls
(gives only the script owner read/execute permission)
