find filenames NOT ending in specific extensions on Unix?

Question

Or without ( and the need to escape it:

find . -not -name "*.exe" -not -name "*.dll"

and to also exclude the listing of directories

find . -not -name "*.exe" -not -name "*.dll" -not -type d

or in positive logic ;-)

find . -not -name "*.exe" -not -name "*.dll" -type f

find . ! \( -name "*.exe" -o -name "*.dll" \)

$ find . -name \*.exe -o -name \*.dll -o -print

The first two -name options have no -print option, so they skipped. Everything else is printed.

You could do something using the grep command:

find . | grep -v '(dll|exe)$'

The -v flag on grep specifically means "find things that don't match this expression."

Unix find command reference

find  /data1/batch/source/export   -type f -not  -name "*.dll" -not -name "*.exe"

Linux/OS X:

Starting from the current directory, recursively find all files ending in .dll or .exe

find . -type f | grep -P "\.dll$|\.exe$"

Starting from the current directory, recursively find all files that DON'T end in .dll or .exe

find . -type f | grep -vP "\.dll$|\.exe$"

Notes:

(1) The P option in grep indicates that we are using the Perl style to write our regular expressions to be used in conjunction with the grep command. For the purpose of excecuting the grep command in conjunction with regular expressions, I find that the Perl style is the most powerful style around.

(2) The v option in grep instructs the shell to exclude any file that satisfies the regular expression

(3) The $ character at the end of say ".dll$" is a delimiter control character that tells the shell that the filename string ends with ".dll"
