POSIX shell 相当于 <()

Question

<(commands ...) in bash/zsh 将输出行为作为一个文件。 是否存在 POSIX 等价物？

Answer 1

mkfifo foo.fifo

## if your "commands" is multiple commands
# { commands ...; } >foo.fifo &

# otherwise, if it's just one
commands ... >foo.fifo &

something_else foo.fifo

最接近

something_else <( commands ... )
