how to make alias of multiple files at once ???

Hi Detlef!

Do you mean a symbolic link? If so, it should be pretty easy:


ln -s /path/to/your/directory/* /new/path/to/where/you/want/links/.

>A more advances task would be to make alias to all files in a folder and the folders sub-folders with the extension .MP3. Is there a way to do that ?

You can do this via find:

find /path/to/original/dir -name "*.mp3" -exec ln -s {} /path/to/alias/dir/ \;

This will search for all files that match *.mp3 in the directory /path/to/original/dir and for each match it will execute the ln command (where {} is replaced by the path to the found item).

Hi Detlef,
Yes, as far as I know real aliases can only be created with AppleScript. However, one of the cleverest things Apple did was to arrange for hooks between AppleScripts and shell scripts. Thus you can still use Camelot's excellent find command to batch create aliases, like so:

find /path/to/original/dir -name "*.mp3" -exec osascript -e 'tell application "Finder" to make alias file at POSIX file "/path/to/alias/dir" to POSIX file "'{}\" \;

I've tested the above command and it works but I've only tested is with absolute paths in all places. I would guess that AppleScript's "POSIX file" can only deal with absolute paths so I recommend that you also use only absolute paths if you use this command.

Detlef and I went to grad school together in the same research group.

Hi Bill,
That's cool! Did you both acquire your taste for Mac's there? Where was that out of curiosity? I went to SUNY Stony Brook.

It is where I

a) used a mac IIe or whatever it was called.

b) Learned my first "real" operating system: VMS

c) Used an Evans and Southerland that costs probably $150K in 1980s dollars to do graphics display

d) Used SGI indigo IIs when they became the thing to have, developing my distaste for Irix at an early age.

e) Had to use Unicos on a Cray.

f) Digitized xray films on a scanner hooked up to a VAX PDP11

g) Learned to write some really bad fortran

h) Stored data on reel-to-reel tapes bigger in diameter than frisbees

i) Watched a 3 day riot over a volleyball court

Hi Bill,
Interesting! In undergrad school I took an intro CS course in which we submitted our programs on punch cards. Possibly as a consequence it wasn't until the PowerPC came out that I did much else with computers.

In Differential Geometry, Berkeley and Stony Brook were two of the top three schools in the world. (all roughly equivalent) Stony Brook stole my advisor from Berkeley shortly after I got there. We didn't have any riots but the Gucci Fireworks factory blew up while I was there.

Hi Detlef,
That's pretty impressive, beating out one's advisor! Actually, that's not unlike my story. In solving my thesis problem, I ended up proving the exact opposite of what my advisor originally asked my to prove. He had asked me to prove something that was actually as far from true as is possible.

The joke is on me; we have just obtained a new structure that changes everything.

As for differential geometry, I wouldn't know an exterior derivative if it came up and bit me in the 2-form. I guess my learning curve is too incremental. In fiber bundle space, no one can hear you scream.
