Ubuntu 13.04：查找以。结尾的文件

Question

Can someone please tell me how I'm misusing find?

I want to find all files in a directory that end in .config.

$:~/esrc$ find . -type f
./t.config
./util/ebin/config.beam
./util/ebin/gen_spec.beam
./util/etc/util.config
./util/etc/v.config
./util/src/config.erl
./util/src/gen_spec.erl
./util/src/v.config
./util/u.config

My first thought was to use find . -type f -name *.config

Unfortunately that's only finding a file in the root directory.

$:~/esrc$ find . -type f -name *.config
./t.config

The same command does work to find all *.erl files though...

$:~/esrc$ find . -type f -name *.erl
./util/src/config.erl
./util/src/gen_spec.erl

Any clue why this works for *.erl but not *.config?

Thanks.

find . -type f -name '*.config'

The confusion here is that the wildcard (the * character) is interpreted by the shell before it makes it to the find command. To get around that issue you need to escape it:

find . -type f -name \*.config

By escaping the * with the \\ the shell will pass the * through to the find command.

An example would be if you had a file named foo.config in the current directory, the shell would expand the wildcard to foo.config and pass that to find, so the resulting command from the find command's perspective would be:

find . -type f -name foo.config
