POSIX shell相当于<()

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

是最接近的等价物

something_else <( commands ... )
