https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D256473 --- Comment #6 from Jason W. Bacon <jwb@freebsd.org> --- (In reply to Stefan E=C3=9Fer from comment #4) >> FreeBSD coral.acadix bacon ~/Test 1032: ls >> aardvark Alan Bob zip >> FreeBSD coral.acadix bacon ~/Test 1033: ls -d [A-Z]* >Alan Bob zip >This is to be expected. The sequence is: "AaBb..Zz" and you are selecting = for >all initial letters except for the files starting with "z" (which come= s after >"Z"). I see the pattern now, but your range expansion above is incorrect and does= n't agree with the ls output I provided. The lower case letters actually come first, which is not what I expected either. That's why the output seemed inexplicable at first. [A-Z] =3D=3D [AbB..zZ] =3D=3D all letters except 'a' [a-z] =3D=3D [aAbB..z] =3D=3D all letters except 'Z' [A-Z]* selects for all but those that start with 'a', not 'z'. This explai= ns why zip is listed and aardvark is not. Adding one more file to clarify: FreeBSD coral.acadix bacon ~/Test 1013: ls aardvark Alan Bob Zed zip FreeBSD coral.acadix bacon ~/Test 1014: ls -d [A-Z]* Alan Bob Zed zip FreeBSD coral.acadix bacon ~/Test 1015: ls -d [a-z]* aardvark Alan Bob zip FreeBSD coral.acadix bacon ~/Test 1020: ls -d [A-z]* Alan Bob zip FreeBSD coral.acadix bacon ~/Test 1021: ls -d [a-Z]* aardvark Alan Bob Zed zip globasciirnages appears to be on by default in the bash port (not from anyt= hing in my env), but disabling with with shopt -u does make bash behave like tcs= h. --=20 You are receiving this mail because: You are the assignee for the bug.=
