# tests for printf numbered conversion specifications, mostly from coreutils

# basic tests

printf '%2$s %1$s\n' world hello
printf '%3$s %2$s %1$s\n' A B C D

# repeat
printf '%1$d %1$d\n' 42

# reuse format string
printf '%3$s %1$s\n' one two three four

# repeat and reuse format string
printf '%1$d%1$d\n' 1 2

# cannot reliably mix numbered and unnumbered conversions
