What does dd represent?
I recognize quite possibly what the command does, yet
info dd inform me: 'Convert and also replicate a documents', as does GNU Coreutils.
Google claims its an acronym of every little thing in between medication and also negative webchat vernacular ; other than a person claiming it suggests 'information destroyer', something made use of in COMPUTER forensics - I would certainly be alarmed if my dd damaged my information!
Any kind of understanding?: -)
Update : Of training course I needed to examine the jargon file:
The Unix dd (1) was made with an unusual, clearly non - Unixy search phrase alternative syntax evocative IBM System/360 JCL (which had an intricate DD 'Dataset Definition' requirements for I/O tools)
Still appears attractive unclear, yet after that it claims:
though the command loaded a demand, the user interface layout was plainly a trick.
Though the "ideal solution" was offered, this site states otherwise:
Actually, it represents 'Copy and also Convert' and also was relabelled to
ddjust due to the fact that
ccwas booked for the C compiler! This is the genuine details I obtained from the male web pages of our Unix - V7 on our college PDP 11.
