Symbolic Links for Lunks (Re-Thunk)

[karron at MCIRPS2.MED.NYU.EDU]

I guess that you wrote tlink(1) ? It looks like you have done what I wanted to
do only did not think about it yet. Great!

You might want to get sgi to put a cross reference in the man page for link to
your tlink. That would clue us in to your good work.

Dangling links:

Here is how I get dangling links ...
cut-----------------------------------------------------------------------
#! /bin/sh
# run this below / so you don't hit your head
# on the root directory...
rm -rf D.DangleDirectory REAL_FILE
cd $HOME
mkdir D.DangleDirectory
echo "THE REAL FILE CONTENTS" > REAL_FILE
pwd
ln -s REAL_FILE D.DangleDirectory/SYMLINK
ls -l REAL_FILE
ls -l D.DangleDirectory/SYMLINK
cat D.DangleDirectory/SYMLINK
cd D.DangleDirectory
pwd
ls -l SYMLINK
cat SYMLINK
echo "try more qualified names"
cd $HOME
ln -s ./REAL_FILE ./D.DangleDirectory/SYMLINK1
ls -l REAL_FILE
ls -l ./D.DangleDirectory/SYMLINK1
cat ./D.DangleDirectory/SYMLINK1
cd D.DangleDirectory
pwd
ls -l ./SYMLINK1
cat ./SYMLINK1
echo "now try doing it the expected way"
cd $HOME
cd D.DangleDirectory
pwd
ln -s ../REAL_FILE SYMLINK2
ls -l ../REAL_FILE
ls -l SYMLINK2
cat SYMLINK2
echo "try fully qualified names"
cd $HOME
pwd
ln -s $HOME/REAL_FILE $HOME/D.DangleDirectory/QUALIFIED_LINK
ls -l $HOME/REAL_FILE
ls -l $HOME/D.DangleDirectory/QUALIFIED_LINK
cat $HOME/D.DangleDirectory/QUALIFIED_LINK
cd D.DangleDirectory
pwd
ls -l QUALIFIED_LINK
cat QUALIFIED_LINK
exit 0
