Listing files with an certain extension
I'm suppose to write a command that would list all files that end in .tx with an optional t at the end.

So far all I got is listing the files that end in .tx which is:

Code:
ls *.tx

Now my problem is how do I add the optional t at the end.

Try:
Code:
ls *.tx *.txt

Try:
[CODE]ls *.tx[t][/CODE]
EDIT:
Oops, was too certain it would work.

Try this instead:
Code:
ls *.{tx,txt}
