Problem in Chapter 6.6

FLLinux · 07-17-2008, 02:28 PM

I am working through the 6.3 version of the book and in chapter 6.6 it has you create a few links. One of them is
ln -sv /tools/bin/perl /usr/bin

Should this have been
ln -sv /tools/bin/perl /usr/bin/perl

So there is a link to the perl tool that was created early from /usr/bin/perl and not turn /usr/bin into a link to /tools/bin/perl?

Thanks

So long as the directory /usr/bin already exists (which it should, from the previous step), "ln" will, by default, create a link with the same name as the source file. IE, it will create a link from /usr/bin/perl to /tools/bin/perl. This is just the same way as "cp" or "mv" work. (In fact, "cp -s" does largely the same thing as "ln -s".)

If you do this as described - you have a symbolic link /usr/bin/perl which points to /tools/bin/perl.
If you do it as you suggest - the result is the same.
Point is: it works as it is described.
Check it after executing the command!
ls -al /usr/bin/perl
