When I go to look at localize.sh from time to time, I have to get out
the old Usenet references to figure out what it all means. It needs
comments!
localize.sh uses ed(1) for editing, but that doesn't allow for
commenting in the edit script. Fortunately we have ex(1) on our
system, and ex(1) does everything that ed(1) does, plus it allows for
comments.
A comment in ex(1) is a double quote --> " at the begining of
a line or after a command (whitespace after a command is ignored).
For example, here's an excerpt from our localize.sh:
ex - Makefile <<'EOF'
" edit script begins here
g/^BATCHDIR/s;/usr/spool/batch;/usr/spool/bnews; " where batchfiles go
g/^NEWSUSR/s/news/netnews/ " Usenet admin id
g/^LIBDIR/s;/usr/lib/news;/usr/local/lib/news; " news library
g/^BINDIR/s;/usr/bin;/usr/local/bin; " where readnews, et al, go
g/^MINDISKFREE/s/= 0$/= 4096/ " for sendbatch
g/^LIBS/s/$/ -ldbm -la # dbm(3x) in -ldbm, ftime(2) in -la/
g/^MISC/s/ftime.o// " see above
... and so on. ex(1) lets you do more fun stuff than ed(1), too,
but I just wanted the comments. :-)
