This is true in shell scripts, but *not* in makefiles, (where the entire compound command must appear on one *logical* line). Thus, it makes no semantic difference, in makefiles, whether the logical operator appears at the end of the continued line, or at the start of the continuation; the continued line *must* end with a backslash in either case. > > Starting with the operator is GNU style, AFAIK, and it is used > throughout the groff code. > This may be so; I don't know. However, although I have occasionally exploited the feature of operator implied continuation, when writing shell scripts, I confess to a personal stylistic preference for placement of the operator at the start of a continuation line; this is the style I always prefer in makefiles. Just my 2p. -- Regards, Keith.
