Create alias files (not alias commands)

If one:
Code:
$ find -name 'some expression' -type f > newfile

and then subsequently wants to create an alias file from each pathname the find command retrieved and the > placed within 'newfile', how would one do this? Ideally, the newly created alias files would all be in one directory.

I am on a Mac OS X 10.7. The notion of an alias file is a 'file.txt alias' that points to another 'file.txt'. 'file.txt alias' only points to where the data represented by the same pathname actually is.

Thanks!

This will create, for example, "file.txt alias" in current directory from /path/to/file.txt, etc
Code:
find -name 'some exp' -type f -exec bash -c 'ln -s $1 "${1##*/} alias"' _ {} \;

Great advice:)

That was SUPER helpful! Is there a way to send to resultant alias files to a different directory at the same time? (only in an attempt to not have to have the current as directory the destination of the aliases).


I tried the above with some test files first and that did work!

Trying it with the files I was originally targeting produced: no such file or directory errors and no aliases.

Being more specific, I:

directory_for_aliases
Code:
 $ find /directory/containing/files -name 'expression' -not \
-name 'expression'  -exec bash -c 'ln -s $1 "S{1##*/} alias"' _ {} \;
ln: filename1 alias: No such file or directory
ln: filename2 alias: No such file or directory 
.
.

You'd place that in the 2nd argument to ln. Also, I missed some quotes around $1 before (would cause problems with filenames already containing space)

This way:
Code:
find -name 'some exp' -type f -exec bash -c 'ln -s "$1" "/new/path/${1##*/} alias"' _ {} \;

or this way:
Code:
find -name 'some exp' -type f -exec bash -c 'ln -s "$1" "$2/${1##*/} alias"' _ {} "/new/path/here" \;
