[-- Attachment #1 --] Dear folks, I have recently found a find(1) feature (or bug) that, it would exit immediately if the working directory is not accessible. HOW TO REPEAT: [su to root] cd /tmp mkdir find_testcase chmod 700 find_testcase cd find_testcase [su to your user, e.g. su delphij] Now that we have an non-accessible working directory (/tmp/find_testcase). Any attempt of find would fail with: find: .: Permission Denied This was caused by line 157-158 of find/main.c, which was inherted from 4.4BSD. This behavior also exists in CentOS 3.5, OpenBSD 3.8 and Solaris 8. It seems that the purpose of the code was to conform the POSIX statement that: "-exec ... The current directory for the invocation of utility_name shall be the same as the current directory when the find utility was started. ..." However, it looks somewhat confusing that find(1) refuse to work even if no -exec is specified. So, should we consider this as a feature (add some comments in the BUGS section), or it's a bug that should be fixed?
