From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Worked for me. Thank you!
sfdisk is a script-oriented tool for partitioning any block device.
Not something I've done before, but have you tried fdisk?
fdisk is completely interactive, not suitable for scripting. sfdisk is a "scriptable fdisk".
Even the manpage Telorand linked mentions it by name for non-interactive use.
Also, make sure you use the right program depending on thr partition table : sgdisk is the right choice for GPT disks, sfdisk is for MBR.
There are few fdisk options that work non-interactively, like -l (list partitions). It is impossible to create or delete partitions this way.
From the sfdisk man page:
Since version 2.26 sfdisk supports MBR (DOS), GPT, SUN and SGI disk labels
Depends on what you're doing. There's workarounds for parted that allow you to do things like grow the size of a partition, but by default, you cannot shrink a partition via command line because the design philosophy of parted is that it should by default try to not delete any data. So growing via command line seems fine, but otherwise not so much.
Here on stackoverflow, there's some directions on how to use the ---pretend-input-tty flag to use parted in a script.
Why there isn't something like --no-confirmation flag?
