```
- To create big dummy files really fast, use `truncate` (creates [sparse file](https://en.wikipedia.org/wiki/Sparse_file)) or
- `fallocate`: available for ext4, xfs, btrfs and ocfs2 filesystems
- `xfs_mkfile`: almost any filesystems, comes in xfsprogs package
- `mkfile`: is there for Unix-like systems like Solaris, Mac OS X etc
## System debugging
- For web debugging, `curl` and `curl -I` are handy, or their `wget` equivalents, or the more modern [`httpie`](https://github.com/jkbrzt/httpie).
