Unix Equivalent of DOS COPY CON

This is an answer to a question I got by e-mail.

"A lot of times I need to create a quick text file, like a script (like I used to create Batch files in DOS/Windows). I used to use COPY CON for this. How can I do this in Unix?"

This is just as easy in Unix. Instead of COPY CON filename, use cat >filename. As before enter the text for the file. Then close the file by hitting enter one more time and entering control-D. Remember, if you are creating a shell script, make the file executable with chmod +x filename. Also, to execute the script, remember to include the path to the script, even if you are in the same directory as the script, like this ./scriptname.
