Actually, 'tr -- -a-z _A-Z' is not universally supported, and leading
dash caused a failure; so after better testing, I'm actually pushing:
tr 'a-z-' 'A-Z_'
solaris needs [] around ranges
Thanks. The autoconf manual was not clear on that point:
Not all versions of @command{tr} recognize ranges of characters: at
least Solaris @command{/usr/bin/tr} still fails to do so. But you can
use @command{/usr/xpg4/bin/tr} instead.
@example
$ @kbd{echo "Hazy Fantazy" | LC_ALL=C /usr/bin/tr a-z A-Z}
HAZy FAntAZy
$ @kbd{echo "Hazy Fantazy" | LC_ALL=C /usr/xpg4/bin/tr a-z A-Z}
HAZY FANTAZY
@end example
It looks like I have a documentation patch to write, since you are
indeed correct:
$ echo "Hazy Fantazy" | LC_ALL=C /usr/bin/tr '[a-z]' '[A-Z]'
HAZY FANTAZY
And meanwhile, I guess I'd better add those [] back in, since it never
hurts to transliterate a character to itself on a POSIX-compliant tr.
