Bash Version: 4.1 Patch Level: 9 Release Status: release Description: Negative or zero arguments to yank-last-arg in bound keystrokes do not perform as expected when the keystroke is pressed repeatedly. Comparing to yank-last-arg with no arguments or positive arguments which step backwards successively through history entries, when the argument is zero or negative, repeated keypresses only alternate between the two previous history entries. Also present in: GNU bash, version 4.1.0(1)-release (i686-pc-linux-gnu) GNU bash, version 4.0.33(1)-release (i486-pc-linux-gnu) GNU bash, version 3.2.51(24)-release (i686-pc-cygwin) Repeat-By: Create these keystroke bindings using whatever keystrokes you like. The demo below will use Alt-h, Alt-i, Alt-j, Alt-k and Alt-m: bind '"\eh": "\e1\e."' bind '"\ei": "\e0\e."' bind '"\ej": "\e-\e."' bind '"\ek": "\e-1\e."' bind '"\em": "\e-2\e."' Enter four example commands for testing. It doesn't matter what they are as long as they are different commands and have a few arguments that differ so it's easy to see the demonstration. printf '%s\n' foo bar echo aaa bbb ccc ls -ld . .. getent passwd root sys Press Alt-h four times, you should correctly get "passwd", "-ld", "aaa" and "'%s\n'" in succession. Clear the line (Ctrl-u). Alt-. also correctly gives "sys", "..", "ccc" and "bar". (Ctrl-u to clear) Now try the same thing with each of the other keystrokes, clearing the line between each test. Alt-i: Instead of "getent", "ls", "echo" and "printf" you will see "getent", "getent", "ls" and "getent". Subsequent repetitions will alternate between "ls" and "getent". Alt-j: Instead of "root", ".", "bbb" and "foo" you will see "root", "root", "." and "root". Subsequent repetitions will alternate between "." and "root". Alt-k: Same behavior as Alt-j. Alt-m: Instead of "passwd", "-ld", "aaa" and "'%s\n'" you will see "passwd", "passwd", "-ld" and "passwd". Subsequent repetitions will alternate between "-ld" and "passwd". Other negative arguments behave similarly.
