当只有`read（2）`出现在Bash中的`whatis`时，如何看到`read`命令的手册页？

Question

On Ubuntu Linux 16.04 LTS, I want to see the man page of the read command used to, eg, split input up into an array in the Bash shell.

However, the whatis command displays only this information:

nlykkei@nlykkei-Ubuntu:~$ whatis read
read (2)             - read from a file descriptor

But the read(2) section of the man pages only documents the system call (and the associated C function).

How do I read the man page of the read command used in the terminal?

Answer 1

read is a bash buitin command. See: type read and help read

If you want to see help read in man page style: help -m read | less help -m read | less
