I'm sending messages to this group using both the mailing lists and the nntp, but unfortunately the two seem poorly connected so that my mails don't get pushed from one end to the other in the span of 20 hours. Pierre, I referred to specific sections of the manual in my previous "lost" message, here pasted: --------------------------------------------------------------------- FROM Davide Baldini On 02/27/12 04:11, Dan Douglas wrote: > "If word is unquoted, all lines of the here-document are subjected to > parameter expansion, command substitution, and arithmetic expansion." > > No pathname expansion. That section of manual doesn't specifically include word splitting nor pathname expansion into the list of performed expansions, but the word splitting does include itself unconditionally: > Word Splitting > The shell scans the results of parameter expansion, command substitu- > tion, and arithmetic expansion that did not occur within double quotes > for word splitting. and pathname expansion ties itself to word splitting: > Pathname Expansion > After word splitting, [...] If intended behaviour is to exclude some expansions from performing word splitting or pathname expansion, they should be specifically pointed out in the manual, like the assignment operator section does: > A variable may be assigned to by a statement of the form > > name=[value] > > [...] All values undergo tilde expansion, parameter and variable > expansion, command substitution, arithmetic expansion, and quote > removal (see EXPANSION below).
