No, actually it was quoted part that was bash-specific. Problematic condition was testing for return code 1 after cd ( '[ "$?" = "1" ]' ). Compare this: $ bash -c 'cd foo; echo $?' bash: line 0: cd: foo: No such file or directory 1 To this: $ dash -c 'cd foo; echo $?' dash: 1: cd: can't cd to foo 2 Reco
