You are on the command line and are searching for certain file names in a directory. You know that the command:

Code:

ls te[stf]*

will return with all files in the directory beginning with the letters "te" and containing any of the characters in the brackets, then anything afterwards. You want to search for all files in this directory that begin with "te" but do not contain the letter "f" in the file name and then anything afterwards. Of the selections below, which would be the proper command? Select only one answer.

1. ls te[#f]*
2. ls te[!f]*
3. ls te[&f]*
4. ls te[^f]*
5. ls te[<f]*
6. ls te[>f]*

Answer later.

 

I say 2...

Just because I remember that in C++ and VB != means not equal to, so I take it the ! means not?!

 

Answer time. Jellyman nailed it. The answer is #2. The "!" symbol between the brackets means that you want the search pattern to return a result with none of the characters (in this case "f") to be returned.
