 ===== Fixes =====
+==== Copying ====
+The progress bar when copying files from, for example, your hard disk to a USB drive, will usually fill up, then be stuck at 100% for a while. This isn't really a bug, //per se//: the bar fills when the data has been completely copied to the cache, then goes away when the data has finished moving to the disk. It's annoying!
+You can work round this by using [[rsync]] for larger files—
+<code>rsync -av --progress [source] [destination]</code>
+—or be more adventurous and mess with some system setup:
+  * https://askubuntu.com/questions/122113/copy-to-usb-memory-stick-really-slow
+  * https://forum.manjaro.org/t/copying-progress-bar-hangs-at-100-when-copying-to-thumb-drive/37108
+  * https://lonesysadmin.net/2013/12/22/better-linux-disk-caching-performance-vm-dirty_ratio/
+==== Default Programs ====
+You can set the default programs used to open files by:
+  - Finding the name of the program's desktop file
+    * It should be in ''/usr/share/applications'' or ''~/.local/share/applications''
+  - Use ''xdg-mime'' to set the default, eg: ''xdg-mime default pcmanfm.desktop inode/directory''
+You can confirm with ''xdg-mime query default inode/directory''
+There are also GUI tools to do this, and if you use a //desktop environment// you probably have one already installed.
 ==== Memory ====
 Not having a great time with the kernal's OOM((__O__ut-__O__f-__M__emory)) Killer at the moment; it's not doing the job I expected it to, and I'm getting freezes when I get down to about 1GB of RAM.

 I forget how to do shit a lot.
-==== Renaming Multiple Files ====
+==== Pausing Terminal ====
-For me, **[[mmv]]** has the easiest syntax to remember. You'll probably have to install it.
+You can pause activity in the [[terminal]] with ''Ctrl+s'', and resume again with ''Ctrl+q'', which I find handy sometimes when I'm doing updates.
-''mmv [options] [from] [to]''
+If you think of it beforehand you can pipe output to [[less]] or [[more]] or send it to a file, but I never remember.
-You use ''#[number]'' in your ''[to]'' to represent //wildcards// in your ''[from]''.
+==== Renaming Multiple Files ====
+For me, **[[mmv]]** has the easiest syntax to remember. You'll probably have to install it. There's a version of [[rename]] that uses [[Perl]] and allows [[regular expression]]s.
-=== Examples ===
-Rename all files ''Treme SxxExx.mp4'' to ''SxxExx.mp4''\\
+Otherwise, [[GPRename]] is a graphical tool for batch renaming, and most [[file_manager|file managers]] should have some kind of batch file renaming built-in ([[Thunar]] does, [[pcmanfm]] doesn't).
-''mmv "Treme *" "#1"''
