If you type man dd, the function of the tool will be described as "copy and convert". I can't find the video but there is an interview in which Kernighan, I think, explains that the tool should have been named cc but it was not possible because it was already taken by the c compiler.
- dredmorbius 4y agoThe IBM webpage only covers a few of the JCL DD parameters. There are more at pp. 486ff in Doug Lowe, MVS JCL (1994) here: http://library.lol/main/6784CBC9EE9BBA5AD26993F497514661 http://library.lol/main/6784CBC9EE9BBA5AD26993F497514661 It's still a rather rough fit, though I'm still pretty sure the connection exists. Keep in mind that Unix dd dates to the early 1970s, and JCL itself may have evolved.
