Subject: * vidir: Don't abort if it sees an empty or all-whitespace line.
X-Git-Tag: 0.15~3
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3095ba17495d0f1871900fcc1c87e6efe9f55f18;p=moreutils

* vidir: Don't abort if it sees an empty or all-whitespace line.
* vidir: If just a filename is removed and the number is left,
  treat this the same as removing the whole line, and delete the file,
  instead of trying to rename the file to "".
* vidir: Remove the periods after the item numbers.
* vidir: Man page improvements. Closes: #378122

 vidir allows editing of the contents of a directory in a text editor. If no
-directory is specified, the current directory is edited. Each item in the
-directory is listed. Delete items to remove them from the directory, or
-edit their names to rename them.

+When editing a directory, each item in the directory will appear on its own
+numbered line. These numbers are how vidir keeps track of what items are
+changed. Delete lines to remove files from the directory, or
+edit filenames to rename files. You can also switch pairs of numbers to
+swap filenames.
 
 Note that if "-" is specified as the directory to edit, it reads a list of
 filenames from stdin and displays those for editing. Alternatively, a list
