I would like to install algobox for my studies but it is impossible for me to install it or even to update my computer. I looked for it and I saw that it was probably a problem of space in my partition.
I made the command "df -h" to see what was in my score and it displayed this:

The /var/tmp does not seem to be mounted separate from / and it looks you still have 3G free

I would suggest running a "df -i" to see the inode utilization at the IUse% column(it must be under 100%) as if you have a lot of small files, each one will utilize one inode and if you are using 100% of inodes you will get the "No space left error".

Why can't run it?
If I run it in the following way, it works:
[usuario#MyPC ~]$ sh ./x11vnc.sh
PORT=5900
First, the permissions, so that you can see that it is in 755.
ls -l
-rw-rw-rw- 1 usuario users 4485 dic 2 11:35 x11vnc.log
-rwxr-xr-x 1 usuario users 117 nov 7 14:06 x11vnc.sh
Second,the script file
cat x11vnc.sh
#!/bin/bash
x11vnc -nap -wait 30 -noxdamage -passwd somepass -display :0 -forever -o ~/x11vnc.log -bg -rfbport 5900
Third, I must clarify the structure of the disks
lsblk

└─nvme0n1p2 259:2 0 256M 0 part /boot
I am the user usuario.
I can edit and modify the x11vnc.sh file as I wish, but I can't run it, and I need to run it to include in the auto-start session of the plasma.
[usuario#MyPC ~]$ ~/x11vnc.sh
-bash: /home/usuario/x11vnc.sh: permission denied
Why can't run it?
If I run it in the following way, it works:
[usuario#MyPC ~]$ sh ./x11vnc.sh
PORT=5900
Thank you all, specially to #CharlesDuffy
I change the fstab line from
UUID=16b711b6-789f-4c27-9d6c-d0f744407f00 /home/usuario ext4 auto,exec,rw,user,relatime 0 2
to
UUID=16b711b6-789f-4c27-9d6c-d0f744407f00 /home/usuario ext4 auto,rw,user,exec,relatime 0 2
The position of exec is important, since user also applies noexec. By putting exec after user, you ensure that exec is set. The most important options should be listed last
this is the normal output of df -h:
df -h

I need to filter it to have:

/dev
/System/Volumes/VM
/System/Volumes/Preboot
/System/Volumes/Update
/System/Volumes/Data
/System/Volumes/Data/home
So basically I need only the "mounted on" column of the command df -h.
Any idea?
df --output=target
If you need mount targets, you can also look at findmnt. It has tons of formatting options, the list you want can be done with
$ findmnt --real -O TARGET
I have this SSD that was in another Ovirt cluster that I destroyed, and now I'm trying to re-purpose this disk but can't seem to clear it. I have tried wipefs and dd but it still shows up in fdisk -l. How can I clear all lvms from this disk?

wipefs -a /dev/sda with a reboot seemed looks to have cleared the disk. Thanks all!
I searched but I found nothing for my problem.
I would like to have in Linux command line the information about the CPU usage and the local HDDs with formatting text like exactly as the examples below for my program.
These examples are command line outputs on MS-Windows.
I hope it is possible on Linux, too.
Thank you

You won't find anything exactly like the output you provided.
The only option is to use for disk space df:

There is no command that gives you a load percentage of the cpu. It's actually impossible to get that with a system call (nor in linux neither in Windows). What you can get is the number of ticks currently executed (for each field, user, system, io,irq idle)..., then call it again a certain amount of time later and calculate it. That way is how work all the commands for reading the cpu percentage.
Here a script bash that gives you that: (just create a file named for example cpu.sh paste this code and execute to see the results)
_estado()
{
cat /proc/stat | grep "cpu " | sed -e 's/ */:/g' -e 's/^cpux//'
}
_ticksconcretos()
{
echo $1 | cut -d ':' -f $2
}

clear
echo "CPU: $PORC %"
done
For the free space You could use something like this:
df -h -x tmpfs -x devtmpfs | awk -F " " '{print $1 " " $4 " " $2}'
wich will give you this output:
Filesystem Free Size
/dev/sda1 16G 25G
/dev/sda5 46G 79G
/dev/sdb8 130G 423G
sda represents the first disk, sda1 the first partition, sda2, the second one etc. you can add (or change) $6 inside the print to get the mount points instead of the partitions, change the order or even more things.
I have a custom board based on am335x. I am building a buildroot for a minimal root filesystem (minimal by size) : boots off as initramfs. I am able to boot the image but unfortunately there are no /dev/mmcblk0 entry.
I would like to know how to make it create that entry.
The following is some log and data to help.

It is booting busybox and using devtmpfs which are defaults for buildroot.
If I use TI's minimalfs, it does show /dev/mmcblk0 so the kernel and device tree are ok. How to solve this.
Regards,
Preetam
You can create this node manually by mknod
mknod [OPTION]... NAME TYPE [MAJOR MINOR]
In your case type would be b (block). Major number you may find in sources or use
cat /proc/devices the minor number is a partition number.
If this is not the case, try to enable udev in buildroot config.
