How to check disk space on Unix servers

I just lately switched from a Home windows server 2016 to a FreeBSD Unix server. I wish to take a look at disk house on Unix command line. How do I in finding out disk house usage data the usage of the Unix command-line possibility?

Unix circle of relatives of working techniques be offering the next instructions to test disk house utilization as consistent with your wishes.

Take a look at disk house on Unix working gadget

Unix command to test disk house:

1. df command – Displays the quantity of disk house used and to be had on Unix report techniques.
2. du command – Show disk utilization statistic for every listing on Unix server.

Methods to show Unix disk utilization statistics

See disk utilization for all information within the present listing. Run:
du -a
To get the disk utilization of a listing tree and every of its subtrees for /house/vivek, input:
du /house/vivek
Alternatively, it’s imaginable to peer outout 1024-byte blocks if you happen to go the -k transfer, input:
du -k /house/vivek
Wish to see overall disk utilization of a listing tree? Check out:
du -s /house/vivek

248088	/house/vivek

One can summarize disk utilization for a selected listing as follows:
du -hs /house

1.4G	/house

Subsequent allow us to display title and dimension of all py (Python) information in a selected listing. Additionally show grand overall on the finish:
du -ch /house/vivek/challenge/mgt1.2/*.py

Getting lend a hand about du command

Check out working the next guy command or see on-line guy web page here:
guy du
whatis du

Methods to show unfastened disk house data on Unix

To view the quantity of unfastened house within the report gadget, check out df command:
df

Wish to display details about /jails/www/ report gadget in 1024-byte blocks layout, run:
df -k /jails/www/

Filesystem      1024-blocks    Used       Avail Capability  Fastened on
zroot/jails/www 10745194355 3152328 10742042027     0%    /jails/www

In a similar fashion, to turn details about /jails/www report gadget in MB blocks layout, input:
df -m /jails/www/

Filesystem      1M-blocks Used    Avail Capability  Fastened on
zroot/jails/www  10493353 3078 10490275     0%    /jails/www

How about GB blocks layout for /jails/www report gadget?, Check out:
df -g /jails/www/

Filesystem      1G-blocks Used Avail Capability  Fastened on
zroot/jails/www     10247    3 10244     0%    /jails/www

Show a grand overall

Go the -c possibility:
df -c
Some model of Unix working techniques can show output in human readable layout. In different phrases, Use unit suffixes: Byte, Kibibyte, Mebibyte, Gibibyte, Tebibyte and Pebibyte:
df -H
Pattern outputs:
