18.8 Showing the Actual Filenames for Symbolic Links

sl
The sl program is a perl (37.1) script that traverses the pathnames supplied on the command line, and for each one, tells you if it had to follow any symbolic links to find the actual filename. Symbolic links to absolute pathnames start over at the left margin. Symbolic links to relative pathnames are aligned vertically with the path element they replace. For example:

$ sl /usr/lib/libXw.a

/usr/lib/libXw.a:
/usr/lib/libXw.a -> /usr/lib/X11/libXw.a
/usr/lib/X11 -> /X11/lib
/X11 -> /usr/local/X11R4
/usr/local/X11R4/lib/libXw.a

$ sl /bin/rnews


/bin -> /usr/bin
/usr/bin/rnews -> /usr/lib/news/rnews
/usr/lib/news -> ../local/lib/news
     local/lib/news/rnews -> inews
                    inews
