And how do you find that? Google search literally is useless for these days, for Average Joe.

Do these days include the nearly seventeen years ago when this question was posted? ;)

  https://www.gnu.org https://www.gnu.org was there for decades, much older than SO and google. I know GNU -> Google -> SO -> LLM is a culture shift, this is how human attention goes. The search engine and LLM only capture the latest group attention and we have short memory. That is why reading is a critical skill for us as human beings, we can't afford to outsource that to machine. (Same with writing.)

Try "info bash" on your system. It's the same manual. In Emacs, when I hit C-h i I get a menu of all my info manuals and I first read the bash one there.

  That is correct. And also simple `man bash`: REDIRECTION Before a command is executed, its input and output may be redirected using a special notation interpreted by the shell. Redirection may also be used to open and close files for the current shell execution environment. The following redirection operators may precede or appear anywhere within a simple command or may follow a command. Redirections are processed in the order they appear, from left to right. In the following descriptions, if the file descriptor number is omitted, and the first character of the redirection operator is <, the redirection refers to the standard input (file descriptor 0). If the first character of the redirection operator is >, the redirection refers to the standard output (file descriptor 1). The word following the redirection operator in the following descriptions, unless otherwise noted, is subjected to brace expansion, tilde expansion, parameter expansion, command substitution, arithmetic expansion, quote removal, pathname expansion, and word splitting. If it expands to more than one word, bash reports an error. Note that the order of redirections is significant. For example, the command ls > dirlist 2>&1 directs both standard output and standard error to the file dirlist, while the command ls 2>&1 > dirlist directs only the standard output to file dirlist, because the standard error was duplicated as standard output before the standard output was redirected to dirlist. ...

    Ah, thanks, didn't realise they put the whole manual into the manpage. For other tools (e.g. make), the info manual is complete but the manpage is just a summary.
