The file permission
there is a directory eg. /home/edp/ , all the files under this directory :
1. the file and directory owner is "user1" ,
2. the permission is 644

I want everyone hv permission to overwrite all files and write a new file to it , but I want the file owner and permssion keep unchange , could suggest what can I do ? thx


I hv one suggestion but not sure whether it will work , because I know the password of "user1" , is it OK to su to the userid "user1" before copy the file ? as I know , the similiar command like below can su to another user before rcp file , but I try it but it is fail to run at localhost , could suggest is it possible ? thx


Further to my suggestion , is it OK to su to the userid "user1" before copy the file ? as I know , the similiar command like below can su to another user before rcp file , but I try it but it is fail to run at localhost , could suggest is it possible ? thx


rcp file user1@remote_host:/home/edp

NAME

       umask - set and get file creation mask

SYNOPSIS

DESCRIPTION

       sets  the  process's  file mode creation mask to cmask and returns the previous value of the mask.  Only the file access permission bits of
       the masks are used.

       The bits set in cmask specify which permission bits to turn off in the mode of the created file, and should be specified using the symbolic
       values defined in stat(5).

EXAMPLES

       The  following creates a file named in the current directory with permissions so that the file can be written only by its owner, and can be
       read or executed only by the owner or processes with group permission, even though group write permission and all  permissions  for  others
       are passed in to

RETURN VALUE

       The previous value of the file mode creation mask is returned.
