2 | * by rmk | ||
3 | * | ||
4 | * Detect filesystem type (on stdin) and output strings for two | ||
5 | * environment variables: | ||
6 | * FSTYPE - filesystem type | ||
7 | * FSSIZE - filesystem size (if known) | ||
8 | * | ||
9 | * We currently detect (in order): | ||
10 | * gzip, cramfs, romfs, xfs, minix, ext3, ext2, reiserfs, jfs | ||
11 | * | ||
12 | * MINIX, ext3 and Reiserfs bits are currently untested. | ||
