Hi, Using dash-0.5.11.1 I found that command -v sometimes will return 0 for a non-executable file. The posix spec says for 'command -v': "Utilities, regular built-in utilities, command_names including a <slash> character, and any implementation-defined functions that are found using the PATH variable" https://pubs.opengroup.org/onlinepubs/9699919799/utilities/command.html And under PATH it says: "in PATH. 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." https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap08.html In the attached test script it will return: $ dash ./test.sh test/testfile 0 Where 'testfile' is an empty file with the permissions of 0644 and not executable. I think this is a bug where 'command -v' should return 1 and not find a file? I've noticed that bash also shares this behavior, but not bash when executed as 'sh' or other shells like mksh, yash and zsh.
