Need help resizing root filesystem
 

Hello,

Can I increase my root directory space ? And if its got full should I be able to run any command ?

I have no idea if you could increase that. It depends on your knowledge, on your configuration. But at least you can try to delete some files....
Please give more informations: your os, your disk layout, partitions ....

Welcome aboard.

There is a percentage of space reserved for the root operator to deal with situations like this, however, I am assuming you are a newbie, & therefore, I would advise backing up any important data & reinstalling.

I normally make a / (around 5GB) & /home (the rest of disk) partitions when installing.

I say you make root filesystem about 20GB and rest all.

Also ext family of filesystems let you keep some space for 'root' user as an emergency in case of disk full condition.

It is set while making or afterwards using 'tune2fs' utility.

Change in above '5' to your required percentage of filesystem space to reserve.
