# bash documentation says that precedence order is:
|
|
# ...
|
|
# expr ? expr1 : expr2
|
|
# = *= /= %= += -= <<= >>= &= ^= |=
|
|
# exprA , exprB
|
|
# but in practice, the rules for expr1 and expr2 are different:
|
|
# assignments and commas in expr1 have higher precedence than :?,
|
|
# but in expr2 they haven't:
|
|
# "v ? 1,2 : 3,4" is parsed as "(v ? (1,2) : 3),4"
|
|
# "v ? a=2 : b=4" is parsed as "(v ? (a=1) : b)=4" (thus, this is a syntax error)
