I would like to append both the last command and the output of the last command to a text file for the purpose of a tutorial.
For example: After I do an
ls in my home directory I see this on the screen
bguiz@sheen:~$ ls Desktop Music Documents
I want to then be able to enter a single command which will append the following to a textfile named
$ ls Desktop Music Documents
The idea is that each time I enter a command, I can log both the command itself and its output to the same file, and after several commands, it will demonstrate a particular series of commands. I know this can be done manually – but why do that if there's an easy alternative, right?
This is what I've cooked up so far:
echo -n "\$ " >> cmd.txt; echo !-1:p >> cmd.txt; !-1 >> cmd.txt
It works, but is rather clunky, and has several gotchas such as not being able to preserve the exact screen formatting.
Is the a more elegant solution?
Thank you for the answers so far, but I have a requiement that it needs to work with pipe, e.g.:
ls -lart | grep ^d
Needs to get this appended in the file:
$ ls -lart | grep ^d drwx------ 14 bguiz staff 4096 2010-03-03 15:52 .cache drwx------ 5 bguiz staff 4096 2010-03-03 09:38 .ssh
