23$BUILTIN pushd-
24$FUNCTION pushd_builtin-
25$DEPENDS_ON PUSHD_AND_POPD-
26$SHORT_DOC pushd [-n] [+N | -N | dir]-
27Add directories to stack.-
28-
29Adds a directory to the top of the directory stack, or rotates-
30the stack, making the new top of the stack the current working-
31directory. With no arguments, exchanges the top two directories.-
32-
33Options:-
34 -n Suppresses the normal change of directory when adding-
35 directories to the stack, so only the stack is manipulated.-
36-
37Arguments:-
38 +N Rotates the stack so that the Nth directory (counting-
39 from the left of the list shown by `dirs', starting with-
40 zero) is at the top.-
41-
42 -N Rotates the stack so that the Nth directory (counting-
43 from the right of the list shown by `dirs', starting with-
44 zero) is at the top.-
45-
46 dir Adds DIR to the directory stack at the top, making it the-
47 new current working directory.-
48-
49The `dirs' builtin displays the directory stack.-
50-
51Exit Status:-
52Returns success unless an invalid argument is supplied or the directory-
53change fails.-
54$END-
55-
56$BUILTIN popd-
57$FUNCTION popd_builtin-
58$DEPENDS_ON PUSHD_AND_POPD-
59$SHORT_DOC popd [-n] [+N | -N]-
60Remove directories from stack.-
61-
62Removes entries from the directory stack. With no arguments, removes-
63the top directory from the stack, and changes to the new top directory.-
64-
65Options:-
66 -n Suppresses the normal change of directory when removing-
67 directories from the stack, so only the stack is manipulated.-
68-
69Arguments:-
70 +N Removes the Nth entry counting from the left of the list-
71 shown by `dirs', starting with zero. For example: `popd +0'-
72 removes the first directory, `popd +1' the second.-
73-
74 -N Removes the Nth entry counting from the right of the list-
75 shown by `dirs', starting with zero. For example: `popd -0'-
76 removes the last directory, `popd -1' the next to last.-
77-
78The `dirs' builtin displays the directory stack.-
79-
80Exit Status:-
81Returns success unless an invalid argument is supplied or the directory-
82change fails.-
83$END-
84-
85$BUILTIN dirs-
86$FUNCTION dirs_builtin-
87$DEPENDS_ON PUSHD_AND_POPD-
88$SHORT_DOC dirs [-clpv] [+N] [-N]-
89Display directory stack.-
90-
91Display the list of currently remembered directories. Directories-
92find their way onto the list with the `pushd' command; you can get-
93back up through the list with the `popd' command.-
94-
95Options:-
96 -c clear the directory stack by deleting all of the elements-
97 -l do not print tilde-prefixed versions of directories relative-
98 to your home directory-
99 -p print the directory stack with one entry per line-
100 -v print the directory stack with one entry per line prefixed-
101 with its position in the stack-
102-
103Arguments:-
104 +N Displays the Nth entry counting from the left of the list-
105 shown by dirs when invoked without options, starting with-
106 zero.-
107-
108 -N Displays the Nth entry counting from the right of the list-
109 shown by dirs when invoked without options, starting with-
110 zero.-
111-
112Exit Status:-
113Returns success unless an invalid option is supplied or an error occurs.-
