| 1638 | Mode for \"editing\" directory listings. | |
| 68d2f12f | 1639 | In Dired, you are \"editing\" a list of the files in a directory and |
| 492d2437 RS |
1640 | \(optionally) its subdirectories, in the format of `ls -lR'. |
| 1641 | Each directory is a page: use \\[backward-page] and \\[forward-page] to move pagewise. | |
| 1642 | \"Editing\" means that you can run shell commands on files, visit, | |
| 1643 | compress, load or byte-compile them, change their file attributes | |
| 1644 | and insert subdirectories into the same buffer. You can \"mark\" | |
| 1645 | files for later commands or \"flag\" them for deletion, either file | |
| 1646 | by file or all files matching certain criteria. | |
| 1647 | You can move using the usual cursor motion commands.\\<dired-mode-map> | |
| 1648 | Letters no longer insert themselves. Digits are prefix arguments. | |
| 1649 | Instead, type \\[dired-flag-file-deletion] to flag a file for Deletion. | |
| 1650 | Type \\[dired-mark] to Mark a file or subdirectory for later commands. | |
| 1651 | Most commands operate on the marked files and use the current file | |
| 1652 | if no files are marked. Use a numeric prefix argument to operate on | |
| 1653 | the next ARG (or previous -ARG if ARG<0) files, or just `1' | |
| 1654 | to operate on the current file only. Prefix arguments override marks. | |
| 1655 | Mark-using commands display a list of failures afterwards. Type \\[dired-summary] | |
| 1656 | to see why something went wrong. | |
| 1657 | Type \\[dired-unmark] to Unmark a file or all files of a subdirectory. | |
| 1658 | Type \\[dired-unmark-backward] to back up one line and unflag. | |
| 1659 | Type \\[dired-do-flagged-delete] to eXecute the deletions requested. | |
| 1660 | Type \\[dired-advertised-find-file] to Find the current line's file | |
| 1661 | (or dired it in another buffer, if it is a directory). | |
| 1662 | Type \\[dired-find-file-other-window] to find file or dired directory in Other window. | |
| 1663 | Type \\[dired-maybe-insert-subdir] to Insert a subdirectory in this buffer. | |
| 1664 | Type \\[dired-do-rename] to Rename a file or move the marked files to another directory. | |
| 1665 | Type \\[dired-do-copy] to Copy files. | |
| ee680b2b JB |
1666 | Type \\[dired-sort-toggle-or-edit] to toggle Sorting by name/date or change the `ls' switches. |
| 1667 | Type \\[revert-buffer] to read all currently expanded directories aGain. | |
| 492d2437 RS |
1668 | This retains all marks and hides subdirs again that were hidden before. |
| 1669 | SPC and DEL can be used to move down and up by lines. | |
