Well, could be done via a make(1) rule, maybe? Aside that, no because you
could use some :: rules generated by some definitions.
.if defined(REGEX_REPLACE)
.for file in ${REGEX_REPLACE_FILES}
regex-replace::
.if defined(REGEX_REPLACE_${file})
sed ${REGEX_REPLACE_${file}} ${file} | tee ${file} > /dev/null
.else
sed ${REGEX_REPLACE} ${file} | tee ${file} > /dev/null
.endif
.endfor
.endif
.if target(regex-replace)
all: regex-replace
.endif
And then in a Makefile,
REGEX_REPLACE= s/foo/bar/
REGEX_REPLACE_foo.c= s/barf/blah/
REGEX_REPLACE_FILES= foo.c bar.blah heh.hoh dum.di.dum
Or similar?
Of course I'm not how sure that "surely" that will work, because I haven't
read tee(1)'s code in a long time, but something along those lines is not
hard.
