[SOLVED] Navigate to disk in BASH

tg0000 · 04-11-2022, 08:45 AM

I'm a bit embarrassed that I can't figure this out on my own. I know how to change directories in BASH but I can't seem to figure out how to change to another disk.

In this case I want to switch to /dev/sdb1 so I tried CD /dev/sdb1 which tells me it's not a directory.

Can you show me the error of my ways?

And yes I promise I read over a few basic tutorials like the one below.

linux does not use the concept of disks like windows. The analogy is that the system is arranged like a tree with the / being the trunk. All other filesystems are attached to root as mount points which is just a directory.

Now days depending on the distribution, desktop an external drives are automatically mounted within /media. you can check using the lsblk command. If not automatically mounted you can mount it manually.

If it isn't an external drive then you will probably need to manually mount the drive. More information might be required.

/dev/sdb1 appears to be mounted since I can access it in the GUI file manager. But I still get the same error attempting to access it in BASH.

because you need to cd into the mount point, not into the device (/dev/sdb1).

/dev/sdb1 is a device name, not a mount point.

Look at the output of the lsblk command. Does a mount point show up for /dev/sdb1?

Depending on distribution / version it might automatically be mounted to /run/username/.. or some other obscure path.

It shows the mount point as ... GoldStandard_NTFS

Code:

NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 465.8G  0 disk 
└─sda1   8:1    0 465.7G  0 part /sysroot
sdb      8:16   0   1.8T  0 disk 
├─sdb1   8:17   0   1.4T  0 part /run/media/dada/GoldStandard_NTFS
└─sdb2   8:18   0   466G  0 part /run/media/dada/Gold_FAT
zram0  252:0    0   5.5G  0 disk [SWAP]

*Edit ...

cd /run/media/dada/GoldStandard_NTFS worked thanks :-)

You can see what the device node of a disk is with:

Code:

dmesg -w

Then plug the hard drive in. The device node will show in the dmesg terminal.
Then you can mount the filesystem somewhere if you want to.

Example:

Code:

mount /dev/sdb1 /mnt/somewhere
cd /mnt/somewhere
ls

If you have an auto mounter running, then it probably is already somewhere in /mnt

look at:
man mount
man cd
man ls
man dmesg
man cp
man mv

Edit:
Oh too late.
