unix find command

Question

how to use the find command to find files/directories which are not matching the pattern. for eg:

find <some options > -name "dontfile.txt"

should give me output of all the find whose file name is not dontfile.txt

Answer 1

Use the -not operator:

find <some options > -not -name "dontfile.txt"

You may need to add parenthesis to get the desired effect, depending on how complex the rest of the command is:

find <some options > \( -not -name "dontfile.txt" \)

Answer 2

find <some options> ! -name "dontfile.txt"

this should be the answer. thanks Dave.
