I was tidying up some data recently and found a couple of ISO images lying around with cryptic file names. I didn’t have cdinfo installed, so I though I’d run less hoping that the binary data would have some useful text in it. Instead I was surprised to see the following:
CD-ROM is in ISO 9660 format
System id: LINUX
Volume id: Ubuntu-Server 9.10 i386
Volume set id:
Publisher id:
Data preparer id:

Looks like less runs isoinfo -f -R -J -i ubuntu-9.10-server-i386.iso. So I did have the tools I needed installed, I just didn’t know it yet :).
