How to use bash to test directory limits of filesystem

问题

I need to test how many directories and files I can create on a filesystem (network mounted and local (usb) drives). I now use this bash line:

for i in {0..999999}; do mkdir -p $i; pushd $i; done

I know that it probably can be done better and I'd like to know how to. (in bash, not too complicated)

回答1:

while (true); do
  mkdir a
  cd a
done

Creates something like ./a/a/a/a/a/a/a/a/a/a/a/a/a/a/a/a/a/a/a/a/a/a/...

回答2:

Any file/directory is represented using an inode, take a look at df -i and you should get an overview of the number of files/directories you have the possiblity to create/use.

The cd method actually works better and faster... My ext4 usb stick starts to mock at about 1040 folders...

And the network part is to test my wins2k3 config, but my virtualbox fails at the moment because I think I screwed something up...
