Thank you for reporint the issue about lsfd. diff-{{{ --- /home/glaubitz/util-linux/tests/expected/lsfd/column-xmode-MODE-x-bit 2023-11-11 18:12:22.478579711 +0000 +++ /home/glaubitz/util-linux/tests/output/lsfd/column-xmode-MODE-x-bit 2023-11-11 18:19:47.434570270 +0000 @@ -1,2 +1,3 @@ r-x +rwx MODE(x-bit): 0 }}}-diff Could you show the outout of "pmap $$" on the target platform? On my PC (Fedora 38 running on x86_64): 929547: zsh 000055e86f2d7000 92K r---- zsh 000055e86f2ee000 716K r-x-- zsh 000055e86f3a1000 88K r---- zsh ... The failed test case is highly depends on "r-x--" iin the line "000055e86f2ee000 716K r-x-- zsh". I guess, on your environment, the field is "rwx--". If, my guessing is correct, I must fix the test case. Masatake YAMATO
