When copying a large file on Linux transfer hangs at the end… And you want to f**king kill someone.

There’s an annoying bug in almost every Linux distribution I’ve worked with. When your copying a large file to usb device (pendrive etc.) it hangs at the end (I mean it haaaaaaaaaaaaangs).

I’ve found a solution that works on Elementary and Ubuntu (at least).

Simply paste this two commands in your terminal:

sudo sh -c 'echo $((48*1024*1024)) > /proc/sys/vm/dirty_bytes'
sudo sh -c 'echo $((16*1024*1024)) > /proc/sys/vm/dirty_background_bytes'

Add this to some kind of startup script and forget about transfer problems…

How to watch file count in a directory (Linux/macOS)?

If you want to monitor file count in some directory simply use this:

watch "ls -A | wc -l"

You can also mask specific files using asterisk char:

watch "ls sess* -A | wc -l"

If you get Argument list too long error, please change command syntax to this:

watch "ls -U | grep -c '^sess'"

How to mirror (statically) a website?

If you want to copy a website really really fast use HTTrack with following switches:

httrack http://website.com/ -K --sockets=50 --disable-security-limits --max-rate=0

It works on Linux (there’s a native Debian package) and Windows.

Check documentation for other options. K is very important because it affects link generation. If you want original links without html extensions use it like above.

K option cheatsheet:

−K0foo.cgi?q=45 −> foo4B54.html?q=45 (relative URI, default)
−K−> http://www.foobar.com/folder/foo.cgi?q=45 (absolute URL) (−−keep−links[=N])
−K3−> /folder/foo.cgi?q=45 (absolute URI)
−K4−> foo.cgi?q=45 (original URL)
−K5−> http://www.foobar.com/folder/foo4B54.html?q=45 (transparent proxy URL)

And last but not least…

If you want to rewrite original links to html static links use this:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)/$ $1.html
RewriteRule ^([^/]+)/([^/]+)/$ /$1/$2.html
RewriteRule ^([^/]+)/([^/]+)/([^/]+)/$ /$1/$2/$3.html
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|/)$
RewriteRule (.*)$ /$1/ [R=301,L]
