x df --csv
```
### Filter and Process
```bash
# Find large filesystems (>100GB)
x df --tsv | awk -F'\t' 'NR>1 && $3 > 100'
# Check specific mount point
x df --tsv | grep "/home"
# Get usage percentages only
x df --tsv | awk -F'\t' '{print $1, $6}'
```
### Data Processing

## Comparison with Native df
| Command | Output |
|---------|--------|
| `df -h` | Basic disk usage |
| `mount` | Mount information |
| `x df` | Combined view with filesystem type and mount attributes |
```bash
# Native df
$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 500G 200G 300G 40% /
# x df (combined with mount info)
$ x df --tsv
Filesystem Type Size Used Avail Use% Mounted_path Mounted_attr
/dev/sda1 ext4 500G 200G 300G 40% / rw,relatime
```
