Aren't 350 000 files too many arguments for for i in *?
Safer and faster is
Code:
find . -type f |
while read i
In theory, no. The for i in * is all processed inside the shell without having to create an argument list like it would for ls * (which would almost certainly fail hitting ARG_MAX limits).
Another possibility would be something like set -- * which would then allow you to use $# to split groups of files instead of going round-robin. Invoking mv for each file to be moved is going to be much slower than invoking mv to move groups of files.
If filenames are of the form <xyz>_n1_n2_n3.pbx would it make more sense to create a directory for each n2 value rather than ten directories with an arbitrary spread of files into those new directories. If part of the filename can be used to determine which directory to search, it should make it much faster to find needed files after the files have been rearranged. If this is of interest to the submitter, we could help come up with a way to help do this.
Hi,

ls -ltr will sort the folders from old to recent.
ls -ltr | awk '{print $9}' will list the folder names (with a blank line at the beginning)

However, if I change the above question a... (1 Reply)

rmf
rmf(1mh)rmf(1mh)Name
rmf - remove folder
Syntax
rmf [ +folder ] [ -help ] [ -[no]interactive ]
Description
The command removes all of the messages within the current folder, and then removes the folder itself. If there are any files within the
folder which are not part of MH, they are not removed, and an error message is displayed.
You can specify a folder other than the current folder by using the +folder argument. If you do not specify a folder, and cannot find the
current folder, asks you whether you want to delete instead.
If the current folder is removed, it makes current.
Note that the command irreversibly deletes messages that do not have other links, so use it with caution.
If the folder being removed is a sub-folder, the parent folder becomes the new current folder, and tells you that this has happened. This
provides an easy mechanism for selecting a set of messages, operating on the list, then removing the list and returning to the current
folder from which the list was extracted.
Using to delete a read-only folder deletes the private sequence and current message information from the file, without affecting the folder
itself. If you have sub-folders within a folder, you must delete all the sub-folders before you can delete the folder itself.
Options-help Prints a list of the valid options to this command.
-interactive
-nointeractive
Asks for confirmation before deleting a folder. By default, deletes a folder and its messages without asking for confirmation.
If you specify the -interactive option, asks if you are sure before deleting the folder. You are advised to use this option,
since when deletes a folder its contents are lost irretrievably.
Examples
This example shows how asks for confirmation when the -interactive option is used:
% rmf -interactive +test
Remove folder "test"? y
