find - link - error
Have a random question:

In simple terms I have a find command on a dir:

/path/user/data/

/path/user is a link to:

/tmp/storage/


The find command outputs the files it finds as:

/path/user/data/file

What I need is:

/tmp/storage/file

Is there a way to "resolve" the Unix (Aix) file to its true location? Have tried numerous find options but to no avail.

the explanation is clear though, what is the find command you used ?

The original command is:

Code:
find ${DATAENV}/raw/archive/storage -mtime +4 -type fd

The ${DATAENV}/raw is the linked area. so find can't tell that the levels preceeding are links.

I tried with the -H and -L and -follow -xdev etc all seem to do nothing and indicate that find thinks its on the /tmp/storage/.... area from the start.

The only way I can see around this is to do some sort of pre-check:

Code:
NEWPATH=$(ls -l ${UKDWENV} | grep raw | sed 's/.*\-> //g')

and then use ${NEWPATH} in the find.

Just seems like there should be a command like ls / other to disclose a files true location.

I don't have a simple solution but on my system /usr/bin/pwd gives the real location of a directory as distinct from the shell builtin pwd.

find + readlink does the trick.
Here is my example setup:
Quote:
> ls -Rl
total 0
drwxr-xr-x 3 user group 102 Jan 21 21:01 dir_1/
drwxr-xr-x 3 user group 102 Jan 21 21:02 dir_2/

./dir_1:
total 0
-rw-r--r-- 1 user group 0 Jan 21 21:01 file_1

./dir_2:
total 8
lrwxr-xr-x 1 user group 12 Jan 21 21:02 file_1 -> dir_1/file_1
If you can afford to run two commands, then do
Code:
> find . \! -type l -print
.
./dir_1
./dir_1/file_1
./dir_2

> find . -type l -exec readlink {} \;
dir_1/file_1

If you need to have it in one command, try
Code:
> find . \( \! -type l -print \) -or \( -type l -exec readlink {} \; \)
.
./dir_1
./dir_1/file_1
./dir_2
dir_1/file_1

which derives from
Code:
> find . \( \! -type l -print \) -or \( -type l -print \)
.
./dir_1
./dir_1/file_1
./dir_2
./dir_2/file_1

Note that readlink removes the './' - but that should not hurt usually. In case it does: normalize all results, and re-add it to all of them...

Thanks for the replies, think both would work if I was searching in the directory above. The issue is its a linked directory and I am searching lower down the path i.e:

${DATAENV}/raw/archive/storage

Where the raw directory is a linked one. So any files found in storage find see's as real files. Don't think what I need, with the restrictions I have has a solution (at least not a simple / one liner :-( ).

Think its going to be a re-write of the script and calling scripts to pass in a new path to the real files.

Thanks for your replies.

---------- Post updated at 04:49 AM ---------- Previous update was at 04:24 AM ----------

Came up with this solution:

Code:
find ${DATAENV}/raw/archive/storage -mtime +4 -type fd | head -1 | 
awk -v DEF=${DATAENV} -v q=\' ' { 
print "echo " $0 " | sed \"s?" DEF "?`df -g " $0 " | awk " q " { print $7 } " q " | tail -1`?g\" " 
} ' | ksh | other-commands-here

Phew.
