has anyone read the chapter?

I am looking for resources on writing a menu now without a dialog box utility in unix
http://www.freeos.com/guides/lsst/

a menu box utility can be seen here

this may be a case of or nested while loop with a keyboard input reader so

I have also looked up a little bit of template complaint letters
http://www.businessballs.com/complaintsletters.htm



this is a mix of different text processing commands
as in java how we use files it doesn't matter much we just need a stream of input data

and the same thing here

so we'll go over a couple of them


like cat where we can create a file

so our command will look like


@cat > file.txt



etc etc etc
enter return enter return
control D and when we use ls
we can see our directory
and $less <filename> will display the contents of our file

control C is to kill


of course we can use our sort utility as well


how do we sort a file and put it in another file?
the Linux kernel is open source which means it is worked on by a lot of people
we create a diff file and patch command it or something
