1430 | Mode for \"editing\" directory listings. | |
68d2f12f | 1431 | In Dired, you are \"editing\" a list of the files in a directory and |
492d2437 RS |
1432 | \(optionally) its subdirectories, in the format of `ls -lR'. |
1433 | Each directory is a page: use \\[backward-page] and \\[forward-page] to move pagewise. | |
1434 | \"Editing\" means that you can run shell commands on files, visit, | |
1435 | compress, load or byte-compile them, change their file attributes | |
1436 | and insert subdirectories into the same buffer. You can \"mark\" | |
1437 | files for later commands or \"flag\" them for deletion, either file | |
1438 | by file or all files matching certain criteria. | |
1439 | You can move using the usual cursor motion commands.\\<dired-mode-map> | |
1440 | Letters no longer insert themselves. Digits are prefix arguments. | |
1441 | Instead, type \\[dired-flag-file-deletion] to flag a file for Deletion. | |
1442 | Type \\[dired-mark] to Mark a file or subdirectory for later commands. | |
1443 | Most commands operate on the marked files and use the current file | |
1444 | if no files are marked. Use a numeric prefix argument to operate on | |
1445 | the next ARG (or previous -ARG if ARG<0) files, or just `1' | |
1446 | to operate on the current file only. Prefix arguments override marks. | |
1447 | Mark-using commands display a list of failures afterwards. Type \\[dired-summary] | |
1448 | to see why something went wrong. | |
1449 | Type \\[dired-unmark] to Unmark a file or all files of a subdirectory. | |
1450 | Type \\[dired-unmark-backward] to back up one line and unflag. | |
1451 | Type \\[dired-do-flagged-delete] to eXecute the deletions requested. | |
1452 | Type \\[dired-advertised-find-file] to Find the current line's file | |
1453 | (or dired it in another buffer, if it is a directory). | |
1454 | Type \\[dired-find-file-other-window] to find file or dired directory in Other window. | |
1455 | Type \\[dired-maybe-insert-subdir] to Insert a subdirectory in this buffer. | |
1456 | Type \\[dired-do-rename] to Rename a file or move the marked files to another directory. | |
1457 | Type \\[dired-do-copy] to Copy files. | |
1458 | Type \\[dired-sort-toggle-or-edit] to toggle sorting by name/date or change the `ls' switches. | |
1459 | Type \\[revert-buffer] to read all currently expanded directories again. | |
1460 | This retains all marks and hides subdirs again that were hidden before. | |
1461 | SPC and DEL can be used to move down and up by lines. | |
1462 | ||
1463 | If dired ever gets confused, you can either type \\[revert-buffer] \ | |
1464 | to read the | |
1465 | directories again, type \\[dired-do-redisplay] \ | |
1466 | to relist a single or the marked files or a | |
1467 | subdirectory, or type \\[dired-build-subdir-alist] to parse the buffer | |
1468 | again for the directory tree. | |
