<p>The operating system /var log files I typically would not
remove. Before attempting to remove any of them, I would ask the
operating system experts if it would be safe to do so. For Ubuntu
for example, I think those experts would be over in the Ubuntu
forums at [1].</p>
<p>The 15 GB is quite large such that I wouldn't expect the
operating system with default logging to instantly cause that but
get larger more gradually over time.</p>
<p>The du command [2] you might find helpful. Below is an example.</p>
<p>First, I looked at the directories in the root folder for seeing
which ones were using the most drive space:<br>
</p>
<p>username@computername:~$ sudo du --exclude=/proc --exclude=/run
-csh /*<br>
0 /bin<br>
197M /boot<br>
4.0K /cdrom<br>
0 /dev<br>
14M /etc<br>
2.6G /home<br>
0 /lib<br>
0 /lib32<br>
0 /lib64<br>
0 /libx32<br>
16K /lost+found<br>
44K /media<br>
4.0K /mnt<br>
4.0K /opt<br>
56K /root<br>
0 /sbin<br>
3.7G /snap<br>
4.0K /srv<br>
2.1G /swapfile<br>
0 /sys<br>
164K /tmp<br>
6.6G /usr<br>
3.2G /var<br>
19G total<br>
</p>
<p>In my case, I'm storing my WIEN2k calculations under
/home/username/wiendata and have my SCRATCH set to the case
folders (with ./) that I put in that directory:<br>
</p>
username@computername:~$ grep wiendata ~/.bashrc<br>
alias cdw="cd /home/username/wiendata"<br>
export W2WEB_CASE_BASEDIR=/home/username/wiendata<br>
username@computername:~$ grep SCRATCH ~/.bashrc<br>
export SCRATCH=./<br>
<p>I can check the space of just the /home directory with:<br>
</p>
<p>username@computername:~$ du -csh /home<br>
2.6G /home<br>
2.6G total<br>
</p>
<p>I see 2.6 GB of space is being used.</p>
<p>I check what I have under my home directory:<br>
</p>
<p>username@computername:~$ ls /home<br>
username<br>
</p>
<p>There I see I only have one user account, which is named
username.</p>
<p>I check how much space is being used by username:<br>
</p>
<p>username@computername:~$ du -csh /home/username<br>
2.6G /home/username<br>
2.6G total</p>
<p>Next, I check under /home/username to see what the 2.6 GB
consists of:<br>
</p>
<p>username@computername:~$ cd /home/username/<br>
username@computername:~$ du -csh * .[^.]*<br>
4.0K Desktop<br>
4.0K Documents<br>
4.0K Downloads<br>
4.0K Music<br>
4.0K Pictures<br>
4.0K Public<br>
124M snap<br>
4.0K Templates<br>
4.0K Videos<br>
1.5G WIEN2k<br>
180M wiendata<br>
4.0K .bash_history<br>
4.0K .bash_logout<br>
4.0K .bashrc<br>
130M .cache<br>
176K .config<br>
12K .gnupg<br>
697M .local<br>
4.0K .profile<br>
4.0K .ssh<br>
0 .sudo_as_admin_successful<br>
4.0K .wget-hsts<br>
2.6G total<br>
</p>
<p>I see my WIEN2k installation is using 1.5 GB of the 2.6 GB used.
My wiendata is currently only using 180 MB.</p>
<p>Looking in my wiendata folder, I currently only have one case
calculation named Al:<br>
</p>
<p>username@computername:~$ ls /home/username/wiendata/<br>
Al</p>
<p>I find it is taking the entire 180 MB:<br>
</p>
<p>username@computername:~$ du -csh /home/username/wiendata/*<br>
180M /home/username/wiendata/Al<br>
180M total<br>
</p>
<p>To display how much is used under the /home directory in MB, I
use:<br>
</p>
<p>username@computername:~$ du -csh --block-size=M /home<br>
2624M /home<br>
2624M total<br>
</p>
<p>I want to move the Al directory from the computer to my USB
connected external storage drive similar to what you described.
First though, since my storage drive has a Windows NTFS partition,
I have to rename the :log file to avoid a transfer error and I
chose to name it log.txt:<br>
</p>
<p>username@computername:~$ mv /home/username/wiendata/Al/:log
/home/username/wiendata/Al/log.txt<br>
</p>
<p>Creating an archive (.tar) or compressed file (.zip) of the Al
directory would have been an alternate solution that would not
have required renaming of the :log file.</p>
<p>I transferred the entire directory to my USB connected flash
drive (mounted at /media/username/1A50-FE2F/Al) using a mv command
in the bash terminal:<br>
</p>
<p>username@computername:~$ mv /home/username/wiendata/Al
/media/username/1A50-FE2F/Al</p>
<p>I rechecked wiendata directory after that and see the Al file is
gone (i.e., was transferred successfully):<br>
</p>
<p>username@computername:~$ ls /home/username/wiendata/</p>
<p>I check the space of /home again:<br>
</p>
<p>username@computername:~$ du -csh --block-size=M /home<br>
2445M /home<br>
2445M total<br>
</p>
<p>I see that the used /home space dropped 179 MB (= 2624M -
2445M). The 1 MB could be due to rounding error or other active
processes going on the system taking it, but I was essentially
able to get an entire 180 MB of free space back for this case as
expected.<br>

<div> Yes, wien2k is installed under
the /home directory. I have also checked /var.
there are log files as mentioned in your reference

<p>If your WIEN2k cases are located somewhere
under the /home directory, is this the
directory you are seeing the space increase
in?</p>
<p>If your looking at the space of the entire
storage drive before and after the
calculation, another possibility is the
increase could be due to normal usage logging
by the operating system. So, if its the /var
you are seeing increase after the calculation,
it could potentially be due to that as log
files could be stored there as seen for
example at [1].<br>

During userconfig you have
specified a SCRATCH directory. Only<br>
you can know what you did there.<br>
<br>
PS: echo $SCRATCH will tell you,
what you specified.<br>

Dear Wien2k users,<br>
<br>
<br>
<br>
<br>
<br>
After running
calculations I am saving<br>
the data in external hdd while
deleting the same from linux.<br>
However, at each time, after
deleting data, I have found that<br>
some amount of spaces are not
recovered. Wien2k is saving some<br>
files in Linux which I am not
able to delete.<br>
<br>
My query is where are those extra
files are stored? Whether<br>
there is some directory called
as _scratch but then I am not<br>
able to find it either?<br>
<br>
<br>
<br>
<br>
<br>
Any response is eagerly awaited.<br>
<br>
<br>
<br>
<br>
<br>
with regards, <span style="white-space:pre-wrap"></span><br>
