Increasing partition of a SD card

I have a SD card that has two partitions /dev/sdb1 that holds the boot sector, and /dev/sdb2 that holds the OS. The card still has unpartitioned free space.

How can I take all the unpartitioned free space and add it to /dev/sdb2 without formatting the drive? I want to do this in on command line only

See man resize2fs.

The sequence of steps is: 1. resize the partition, using any appropriate tool (fdisk, cfdisk, gdisk, &c.), and 2. resize the filesystem, using resize2fs (most likely; there are different tools for different FSs). If you want, you can use gparted to do it automatically.

@goldilocks, I did use resize2fs but it says I am already at full block. When I run parted /dev/sdd/ print free, I have a whole chunk of Free Space. I want to allocate that to my parition

Whoops! You have to increase the partition first w/ fdisk. Resize2fs resizes the filesystem inside. I don't have time to write a complete answer right now, but the fdisk thing means "deleting" the partition then creating it again with the exact same starting block, but then a greater final size. It's pretty straightforward, but you may want to look for an intro to fdisk or something if you haven't used it before.

Ended up using the following. Assuming the disk I want to expand is /dev/sdd and has two partitions /dev/sdd1 and /dev/sdd2, and I want to increase /dev/sdd2.

umount /dev/sdd2
sudo parted /dev/sdd resizepart 2 -- -1
sudo e2fsck -f /dev/sdd2
sudo resize2fs /dev/sdd2

In this example, I wanted to increase to the maximum volume (hence -- -1 as argument of resizepart. If you want to resize to a specific size, I suggest you first run

sudo parted /dev/sdd unit s print free

This should print something similar to

Number Start End Size Type File system Flags
 63s 2047s 1985s Free Space
 1 2048s 32767s 30720s primary fat16 boot, lba
 2 32768s 5119999s 5087232s primary ext2
 5120000s 15728639s 10608640s Free Space

Say you want to expand to sector 10120000s (that's somewhere between the start/end of my free space 5120000s to 15728639s. In that case you run

umount /dev/sdd2
sudo parted /dev/sdd resizepart 2 10120000s
sudo e2fsck -f /dev/sdd2
sudo resize2fs /dev/sdd2

Hope this helps out somebody else as well.
