The OS X Man Pages lists out all builtin functions. But where can I find the documentation of a particular one?
For instance, the command
fc, on ubuntu I can get its manual by:
> help fc fc: fc [-e ename] [-lnr] [first] [last] or fc -s [pat=rep] [command] Display or execute commands from the history list. fc is used to list or edit and re-execute commands from the history list. FIRST and LAST can be numbers specifying the range, or FIRST can be a string, which means the most recent command beginning with that string. ....
Another example is the
if expression, on ubuntu:
> help if if: if COMMANDS; then COMMANDS; [ elif COMMANDS; then COMMANDS; ]... [ else COMMANDS; ] fi Execute commands based on conditional. ...
What am I missing here?
