link files instead of copying

asmar · 04-05-2008, 09:03 AM

Hello all,

I need to execute the following command into a Solaris 5.11 system.

cp -al ......

The problem is that either -a or -l works on Solaris.
Man pages are not installed and all I can get is:

Usage: cp [-f] [-i] [-p] [-@] f1 f2
cp [-f] [-i] [-p] [-@] f1 ... fn d1
cp -r|-R [-H|-L|-P] [-f] [-i] [-p] [-@] d1 ... dn-1 dn

What I want to achieve is link files instead of copying and also keep permissions on files.

Any help is much appreciated.

Thanks

Just found it...
I need to use find and cpio to achieve the same.

Since these are links, the permissions will be the same.

Code:

ll
total 4
-rwxrw-r-- 1 jschiwal jschiwal 0 Apr  5 10:20 abcd
jschiwal@hpamd64:~/demo> mkdir temp
jschiwal@hpamd64:~/demo> cp -l abcd temp/
jschiwal@hpamd64:~/demo> ls -l abcd temp/abcd
-rwxrw-r-- 2 jschiwal jschiwal 0 Apr  5 10:20 abcd
-rwxrw-r-- 2 jschiwal jschiwal 0 Apr  5 10:20 temp/abcd
jschiwal@hpamd64:~/demo> chmod o-r temp/abcd
jschiwal@hpamd64:~/demo> ls -l abcd temp/abcd
-rwxrw---- 2 jschiwal jschiwal 0 Apr  5 10:20 abcd
-rwxrw---- 2 jschiwal jschiwal 0 Apr  5 10:20 temp/abcd

I don't have solaris, so you may want to verify this yourself.

You are using non standard Gnu cp extensions.

Just use /usr/gnu/bin/cp on Solaris Express (a.k.a. SunOS 5.11) to get them, and indeed copying the permission while linking is pointless.
