The only like that I've seen are some pieces of code that sit on top of the shell and provide a VAX/VMS-like comand line interface.
It expects that you know VMS DCL already. Windows PC's have the reverse available- a unix interface - cygwin.
Depending on the shell you use, those commands may be different like: export vs setenv for example.
Just because I haven't seen it doesn't mean there isn't one.
Your best option is to get a copy 'unix in a nutshell' - the Oreilly book. Keep it at your terminal - it has cross referencing like
Delete - see rm
And it groups related commands.
Plus, a lot of stuff you do involves piping to multiple commands
> ll | grep "Oct" | grep -v "2002"
to find files dated October this year but not last year "2002"
So you just have to learn on your own or sit by an experienced user for a while.
