df 명령어 대신 사용할 수 있는 python용 pydf
가상환경에서 사용하기 위해 아래와 같이 설치해 본다.

[root@kwan21c ~]# python3 -m venv pydf
[root@kwan21c ~]# source pydf/bin/activate
(pydf) [root@kwan21c ~]# python3 -m pip install pydf

명령어의 help 내용을 한번 살펴보자
|
(pydf) [root@kwan21c ~]# pydf --help
Usage: pydf [options] arg
Options:
--help show this help message
-v, --version show version
-a, --all include filesystems having 0 blocks
-h, --human-readable print sizes in human readable format (e.g., 1K 234M
2G)
-H, --si likewise, but use powers of 1000 not 1024
-b BLOCKSIZE, --block-size=BLOCKSIZE
use BLOCKSIZE-byte blocks
-l, --local limit listing to local filesystems
-k, --kilobytes like --block-size=1024
-m, --megabytes like --block-size=1048576
-g, --gigabytes like --block-size=1073741824
--blocks use filesystem native block size
--bw do not use colours
--mounts=MOUNTS_FILE File to get mount information from. On normal Linux
systems only /etc/mtab or /proc/mounts make sense.
Some other Unices use /etc/mnttab. Use /proc/mounts
when /etc/mtab is corrupted or inaccessible (the
output looks a bit weird in this case).
-B, --show-binds show 'mount --bind' mounts
-i, --inodes show inode instead of block usage

가독성면에서 df 보다는 조금 괜찮은 듯한 명령어입니다.
df에 질렸다면 한번 써봐도 괜찮을 듯 합니다.
