    copying file from one user directory to another

    Hi,

    I am writing a shell script for copying file from one user account directory to another.
    The code is:
    Code:
    #!/bin/sh
    src_path=/home/bargi
    tgt_path=/home/abc
    cp ${src_path}/a* ${tgt_path}/
    bargi and abc are user's.
    When I run the script it gives me error of permission denied.
    I know that since I am logging with bargi account, I can't copy file to abc account directory.

    I have following question:
    1: Is there a way so that abc allow copying other's user to its account? (may be forcefully applying some techniques to abc account with root access )
    2: How can I implement it in shell script ?

    Can any body help me regarding this ?

    Thanks
    Bargi

    You can't have two permissions at once. Use sudo (or maybe su root) instead. Or ask abc to give bargi permission to write in his home directory and execute that script as bargi (or vice versa)

    You may also want to chown the resulting file to the destination uid and gid.

    How can I make abc to give permission to bargi for write permission?

    Read the chmod man page. If this is not super sensitive stuff, just set the permission the same for everyone, eg, "700" means I can do everything and no one else can even look. "777" means anyone can do whatever they want. It's a bitmask (read=4, write=2, execute=1, so "6" is read+write).

    I'm pretty sure that a sub directory might be subject to the constraints of it's parent, you will have to experiment. I always play root so I don't care, but that is a bad attitude to have

    The best way is propably to give abc read permission for the files. Abc can then copy them into his/her home directory.

    The best approach is to ask root to create a group containing all the users which are allowed to share files with each other. The UNIX group system leaves much to be desires, but isn't totally useless...
    Code:
    //try
    //{
    	if (a) do { f( b); } while(1);
    	else   do { f(!b); } while(1);
    //}
