The default installation creates the alias:
alias which='alias | /usr/bin/which --tty-only --read-alias --show-dot --show-tilde'
OK, so if you issue the 'which' command, it pipes the output of 'alias'
into /usr/bin/which, which would be a list of aliases as arguments to the
/usr/bin/which command, right?
I am assuming that the argument to the 'which' command would be appended
to the back end of the pipe, so 'which man' would expand to
'alias | /usr/bin/which --tty-only --read-alias --show-dot --show-tilde man'
The rest of the default aliases are pretty much useful variations of 'ls',
but what is the point of this?
If I make an alias like 'foo=<print all of the man pages>' then wouldn't
this kind of wipe out the value of the which command?
It would seem from my rookie view that the intent of this alias is to include `pwd` in the 'which' search.
Why do they include every alias definition as input to /usr/bin/which?
