[MLUG] the Linux command "script"

[Mike Miller <EMAIL:PROTECTED>]

This is an interesting command.  I was making a little script of my own 
for temporary use and I named it "script."  Then I made the mistake of 
entering this command...

script

...instead of this command:

./script

A single line appeared telling me "Script started, file is typescript."  I 
realized my mistake, entered the "./script" command and continued on my 
merry way.  A little later I found out that my command history was lost. 
That was a little disturbing, but I thought it might have to do with my 
accidentally running the command "script."  So I took a look at this:

man script

It isn't exactly clear from the documentation that script starts a new 
shell.  So that's why I didn't have my command history.  I hit Ctrl-D and 
that stopped 'script' and returned me to my shell and command history.

Then I looked at the file 'typescript' (the file script had made) and sure 
enough, it contained everything I had seen on the screen.  It's best to 
view it this way because of the control characters:

less -r typescript
