The primary use of Dired is to flag files for deletion and then delete the files previously flagged.
You can flag a file for deletion by moving to the line describing the
file and typing d (
dired-flag-file-deletion). The deletion flag is visible as a `D' at
the beginning of the line. This command moves point to the next line,
so that repeated d commands flag successive files. A numeric
argument serves as a repeat count.
The files are flagged for deletion rather than deleted immediately to
reduce the danger of deleting a file accidentally. Until you direct
Dired to expunge the flagged files, you can remove deletion flags using
the commands u and DEL. u (
just like d, but removes flags rather than making flags.
dired-unmark-backward) moves upward, removing flags;
it is like u with argument -1.
To delete the flagged files, type x (
This command first displays a list of all the file names flagged for
deletion, and requests confirmation with yes. If you confirm,
Dired deletes the flagged files, then deletes their lines from the text
of the Dired buffer. The shortened Dired buffer remains selected.
If you answer no or quit with C-g when asked to confirm, you return immediately to Dired, with the deletion flags still present in the buffer, and no files actually deleted.
