If your Unix box doesn't support bash scripts then do not do the following.
Create a file named version. type chmod 755 version and then copy and paste the code below into the file. Then type "mv version /bin" and presto, type version. A cool full hearty command. If you know more about you're Os you could add echo commands before or after the type of os your running.
Anyways there's a cool contribution from a cool dude.
version:
#!/bin/bash
uname -a
Alias's are pretty awesome as well.
You can add the following to your ~.bash_profile. You can substitute uname -a with any commands.
alias version='uname -a'
alias crazypath='cd /to/the/crazy/long/path/that/i/hate/typing'
logout and back in or:
source ~/.bash_profile
Then type version or crazypath at the command prompt and prepare to be amazed.
