Verify if a system has DVD burners?

Question

Is it possible to verify if the system has a DVD burner installed? I need this for a script.

Answer 1

As said in a comment, there is a cleaner way of doing that: wodim -prcap which gives exactly what you need.

Device seems to be: Generic mmc2 DVD-R/DVD-RW.

Also, dmesg | grep RW, in my case (DVD-RW/BD reader drive) it returns something like

[    2.399074] ata2.00: ATAPI: HL-DT-ST DVDRW/BDROM CT40N, A101, max UDMA/133
[    2.409247] scsi 1:0:0:0: CD-ROM            HL-DT-ST DVDRWBD CT40N    A101 PQ: 0 ANSI: 5

and wodim dev=/dev/cdrom -scanbus:

scsibus1:
        1,0,0   100) 'HL-DT-ST' 'DVDRWBD CT40N   ' 'A101' Removable CD-ROM

Answer 2

Simply enough: lshal|grep dvdr
