Hello, the shell standard section on Command Search and Execution, says command shall be searched for using the PATH environment variable as described in XBD Environment Variables and that section says the value of PATH is split into a list and "The list shall be searched from beginning to end, applying the filename to each prefix, until an executable file with the specified name and appropriate execution permissions is found".
Well, that is not how both dash and bash behave. They do not search until an exec file with appropriate permissions is found. They stop when a regular file or a symlink is found. Then, if that does not refer to an executable with correct permissions, they do not continue but issue an error. Is the standard wrong, are bash and dash wrong or am I wrong? Thank you, Mark
