one reason, but consider, that in Unix, the API has the concept of &quot;current
directory&quot; and &quot;create a file in the current directory&quot;<br>AND another process or thread may at any time rename (mv!) any directory...</span><br><br><span style=" font-size:10pt;font-family:sans-serif">So even it you
&quot;think&quot; you know the name of the directory &nbsp;in which you
are creating a file, you really don't know for sure!</span><br><br><span style=" font-size:10pt;font-family:sans-serif">So, you may ask,
how does the command /bin/pwd work? &nbsp;It follows the parent inode field
of each inode, searches the parent for a matching inode, stashes the name
in a buffer...</span><br><span style=" font-size:10pt;font-family:sans-serif">When it reaches
the root, it prints out the apparent path it found to the root... &nbsp;Which
could be wrong by the time it reaches the root!</span><br><br><span style=" font-size:10pt;font-family:sans-serif">For example:</span><br><br><span style=" font-size:10pt;font-family:sans-serif">[root@~/gpfs-git]$mkdir
