Excluir dispositivos loop * snap da saída lsblk?

No meu caso, eu vejo:

~$ sudo lsblk

Mas útil para mim são discos físicos como sda * , nvme * ..

É possível com alguns dispositivos virtuais temporários hide loop * params? Ou recomende-me, por favor, outro comando para assistir meus dispositivos.

Como o tipo de nó principal de um dispositivo de bloco de loop é 7 (como mostrado em /proc/devices), você pode usar a opção -eou --excludelinha de comando para excluí-los pelo tipo principal:

   -e, --exclude list
          Exclude the devices specified by  the  comma-separated  list  of
          major  device  numbers.   Note  that  RAM  disks  (major=1)  are
          excluded by default.  The filter is  applied  to  the  top-level
          devices only.

Ex.

$ lsblk
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
loop1    7:1    0  17.9M  1 loop /snap/pdftk/1
loop2    7:2    0  89.3M  1 loop /snap/core/6673
loop3    7:3    0  91.1M  1 loop /snap/core/6531
loop4    7:4    0    20K  1 loop /snap/hello-world/27
loop5    7:5    0  50.7M  1 loop /snap/p7zip-desktop/163
loop6    7:6    0    20K  1 loop /snap/hello-world/29
loop7    7:7    0  17.9M  1 loop /snap/pdftk/9
loop8    7:8    0  89.4M  1 loop /snap/core/6818
sda      8:0    0 238.5G  0 disk
├─sda1   8:1    0   9.8G  0 part
├─sda2   8:2    0 164.7G  0 part
├─sda3   8:3    0  31.1G  0 part /
├─sda4   8:4    0     1K  0 part
├─sda5   8:5    0  15.3G  0 part /usr/local
└─sda6   8:6    0  17.7G  0 part /home
sr0     11:0    1  1024M  0 rom

mas

$ lsblk -e7
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 238.5G  0 disk
├─sda1   8:1    0   9.8G  0 part
├─sda2   8:2    0 164.7G  0 part
├─sda3   8:3    0  31.1G  0 part /
├─sda4   8:4    0     1K  0 part
├─sda5   8:5    0  15.3G  0 part /usr/local
└─sda6   8:6    0  17.7G  0 part /home
sr0     11:0    1  1024M  0 rom

Você pode usar greppara filtrar a saída:

lsblk | grep -v '^loop'

Isso removerá as linhas que começam com loop.
