bash - POSIX shell 等价于 <()

Question

<(commands ...)在 bash/zsh 中，将输出行为作为文件。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

是最接近的等效于

something_else <( commands ... )
