Thank you for this video :) There is also the so useful du command with the threshold option to filter only bigger files `du -h -t 100M /tmp/*` for example to show only files greater than 100MB in /tmp

so grateful for this video. I had a '/' directory that was 93% full. Gave the : du -sm / and it was hanging. I guess --max-depth 1 could have helped navigate the filesys in order to pin point which subdirectory was too heavy. thank you for teaching me this switch.

Ha ha, I do the same thing. I've got a bunch of commands that I use with switches that I just type from habit, probably looked them up decades ago, but forgot since then. 'netstat -tunlp' and 'ps -ealf' come to mind right away. I think I'll go man them now.

Regarding the output of the df -hT command is worth to mention that when using ext4, as the filesystem by default, 5% of the blocks will be reserved for the super-user, to avoid fragmentation and if we sum the output of the columns Used + Avail the value will be different from what's displayed in the Size column. (445 GB in this case) and the remaining 23 GB up to the displayed size of 468 GB is in fact the 5% reserved space. This reservation can be adjusted with the help of the tune2fs command.

Great teaching as usual the way you have mastery of the command line and how you move and insert different commands is a teaching within its self. please consider and do a teaching on how you move letters and commands and insert different commands with ease because to a newbie it's difficult to understand how you do what you do.

11:58 Actually mebibytes. And unlike the df command, you add “--si” to ask for decimal units. (Calling them “SI” units is misleading, since the binary multipliers are also defined by SI.)

15:28 And here’s another feature of using du on multiple directories: what happens when one directory is contained within another? For example, my current directory contains source code for some programming project. It also has a .git subdirectory containing the Git commit history for that project. If I do du -ks .
@lawrencedoliveiro9104
2 жыл бұрын
that will show me the total usage for the entire directory. But if I do du -ks .git . now something wonderful happens: it first reports the usage for the .git subdirectory, then it shows the usage for the source directory _minus that of the .git subdirectory_ . So I see just the size of the current source tree, not including the commit history.

8:07 You can specify the -x option multiple times, if you want to exclude more than one filesystem type from the listing. For example, on my Debian system, I have a filesystem of type “devtmpfs” mounted on /dev.

I installed 22.04 with standard “use entire disk” on my 170G SSD and df-H command says half of it is 100% full and I can’t acces the rest! I lonly have xfcedesktop and a few small programs running and it says it’s taking up 77G! No way! Now I can’t upgrade my system because it says there’s no more room. Something’s not right. How do I access the rest of the 80G and how do I clear out the bloat? I’m tempted to scrap the whole thing and start over!

about the 'root drive'- if there are multiple drives is there only 1 that is root over all of them or is it ''root' from each drive? What would make it the 'root'? The fact that is it the initial and 'over all' controlling point that allows access to pretty much (if not) everything else? Also, what is a 'bootable' usb? Are al usb's bootable or no? If not, why not? What are instances of the differences- especially the bootable usb?? Maybe you have vids on these already. I'm not aware of them if they do exist (obviously).

There is always one root directory in a linux system. If you have multiple drives with Linux installed then you will have multiple root directories in corresponding drives. And if you want to use it in one linux system then you need to mount it there as normal directory/file and this directory acts as root for that mounted drive.
