That asks tr to delete all individual instances of 'd', 'i', 'u', and ':' in the input string, regardless of their context. > > Expected output > 8ddddb8d5 > > Actual output > 8b85 The behavior you observed was correct. To get what you want, you need to use a tool that can do substring removal, rather than individual character removal; sed and awk are such tools: $ echo uuid:8ddddb8d5 | sed s/uuid:// 8ddddb8d5 As such, I'm tagging this as not a bug; but feel free to reply with any further questions on the topic. -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3266 Virtualization: qemu.org | libvirt.org
