I was intrigued by BMK's comment that "ed" was never spokend as
"ed"
by "those in the know", which leads me to wonder how things were
spoken. Here is a litte list of how I pronounce things [with others'
versions in brackets]. Others will no doubt be aghast.
ls - "list" sometimes "l s";
rm - "remove";
chmod - "change mode" [but I have heard "ch-mode"]
ar - "archive" [others have said "arrr"]
