Subject: stracing pwd
Date: Sat, 19 Jun 2004 10:29:40 -0500 [thread overview]

Hellow. This just striked me.
I wondered how pwd works, I entered a linked directory, and pwd gives me
the link.
when I tried pwd -h (wrong argument) I saw there are two possible
arguments
I have
/usr/src/linux-2.6.7
/usr/src/linux -> /usr/src/linux-2.6.7
under /usr/src/linux,
pwd prints /usr/src/linux
pwd -L too
pwd -P prints /usr/src/linux-2.6.7
but an strace always shows the same
write(1, "/usr/src/linux-2.6.7\n", 21/usr/src/linux-2.6.7
) = 21
and it prints /usr/src/linux-2.6.7 to stdout no matter the parameter
given to pwd.
Anyone knows why that could happen?
( I haven't seen to the pwd code yet though)
