For example, if you want to perform a word count (wc) on the date.txt file, you can press ! on the date.txt entry listing, В“and it will prompt you in the minibuffer with the ! on date.txt: messageВ”. You can run a shell command on marked files using the ! command. You can create a symbolic link file with the S key. You can compress or uncompress a file with the Z command.ДЄ regular expression search can be done on selected files with the A command. You can change the mode of a file with the M command. If you would like to delete a file, you can press D.

To copy a file, you can press C on a file, and it will prompt you in the minibuffer regarding where you would like to create the new copy. You can perform a number of operations on the marked files and directories. You can change the ls command line options used in the Dired listing using the C-u s key combination. This does not delete the files! You can always press g to refresh the Dired buffer contents. To mark all the files, you can use the В‘* sВ’ key combination.ДЄfter you have selected files, you can remove them from the listing by pressing the k key. * -rw-rw-r- 1 shakthi shakthi 270 Jul 5 09:46 locale.txt The buffer will look like the following: /tmp/test: If you want to invert the selection, use t. * drwxrwxr-x 2 shakthi shakthi 4096 Jul 5 09:46 network * drwxrwxr-x 2 shakthi shakthi 4096 Jul 5 09:46 kernel rw-rw-r- 1 shakthi shakthi 29 Jul 5 09:46 date.txt Total used in directory 24 available 146933432 The resultant Dired buffer is shown below: /tmp/test:

Suppose, you wish to mark all the directories in the Dired buffer, you can use a В‘* /В’ key combination. To undo a selection, you can also use M-del ( M and the Delete key). This is applicable for both files and directories. You can unmark the above selection using the u key. rw-rw-r- 1 shakthi shakthi 270 Jul 5 09:46 locale.txtДrwxrwxr-x 2 shakthi shakthi 4096 Jul 5 09:46 network * -rw-rw-r- 1 shakthi shakthi 29 Jul 5 09:46 date.txtДrwxrwxr-x 2 shakthi shakthi 4096 Jul 5 09:46 kernel Total used in directory 24 available 146933380Дrwxrwxr-x 4 shakthi shakthi 4096 Jul 5 09:53. For example, pressing В‘mВ’ on the date.txt entry will mark it, and this is indicated by an asterisk in front of the line, as shown below: /tmp/test: The m key can be used to mark a file or directory for subsequent operations. In order to run commands on them, you need to first select the files. This will only close the buffer, but the file will still exist! You can use the В‘+В’ key to create a new sub-directory.Дired mode allows you to operate on multiple files and directories.

If you wish to close a buffer, you can use C-k to kill it. You can also type the entire В‘testВ’ buffer name, or type it partially and hit TAB for auto-completion, and hit the return key to get to the В‘testВ’ buffer. If you then press TAB, it will open a new Completions buffer that will list the available buffers. To return to the Dired buffer, you can type C-x b and the minibuffer will prompt you with the message В‘Switch to buffer (В…)В’. This will open the file in a new buffer (view). To view a file, you can place the cursor on its entry and use the f or v key, or simply hit the return key. To enter into a directory, move to its listing in the Dired buffer, and simply hit the return key. You can move to the parent directory using the ^ key. tmp/test:Дrwxrwxr-x 2 shakthi shakthi 4096 Jul 3 11:36 network <- CURSOR If the cursor is at В‘kernelВ’ directory as shown below /tmp/test:Дrwxrwxr-x 2 shakthi shakthi 4096 Jul 3 11:36 kernel В’, the cursor will move to В‘networkВ’, which is the next directory in the buffer. If you wish to move the cursor to the previous and next directories, you can use the В‘В’ keys. You can move to a previous line or the next line in the Dired buffer using the p and n keys, respectively. You can exit from Dired mode by simply pressing q (quit-window) in the Dired buffer. The В‘.В’ listing represents the parent directory, which is В‘/tmpВ’ and owned by the В‘rootВ’ user. The В‘.В’ entry represents the current В‘/tmp/testВ’ directory. The files were created by the user shakthi, and this is indicated in the owner and group fields.

The contents of the buffer are similar to the ls -al output as observed in the terminal. rw-rw-r- 1 shakthi shakthi 270 Jul 3 11:36 locale.txtДrwxrwxr-x 2 shakthi shakthi 4096 Jul 3 11:36 network rw-rw-r- 1 shakthi shakthi 29 Jul 3 11:36 date.txtДrwxrwxr-x 2 shakthi shakthi 4096 Jul 3 11:36 kernel Total used in directory 24 available 146721468Дrwxrwxr-x 4 shakthi shakthi 4096 Jul 3 11:36. You will see a buffer with the following contents: /tmp/test: It will prompt you for the directory to be opened in the buffer where you can input В‘/tmp/testВ’. After opening GNU Emacs, you can enter Dired mode using M-x dired.
