chacl(1)

NAME
     chacl - change the access control list of a file or directory

SYNOPSIS
     chacl acl pathname...
     chacl -b acl dacl pathname...
     chacl -d dacl pathname...

DESCRIPTION
     chacl changes the Access Control List (see acl(4)) for a file or
     directory.  The -b flag indicates that there are two ACLs, the first is
     the access ACL and the second the directory default ACL.  The -d flag
     indicates that there are two ACLs, the first one is the directory default
     ACL and the second the access ACL.  The ACL(s) specified are applied to
     each file in the pathname arguments.

     Each ACL is a string which is processed via acl_from_text(3c).  These
     strings are made up of comma separated clauses each of which is of the
     form, tag:name:perm.  Where tag can be

     "user" (or "u")
          indicating that the entry is a user ACL entry.

     "group" (or "g")
          indicating that the entry is a group ACL entry.

     "other" (or "o")
          indicating that the entry is an other ACL entry.

     "mask" (or "m")
          indicating that the entry is a mask ACL entry.

     name is a string which is the user or group name for the ACL entry.  A
     null name in a user or group ACL entry indicates the file owner or
     owner's group.  perm is the string "rwx" where each of the entries may be
     replaced by a "-" indicating no access of that type, e.g. "r-x", "--x",
     "---".

EXAMPLES
     A minimum ACL:  chacl u::rwx,g::r-x,o::r-- file
     The file ACL is set so that the file's owner has rwx, the file owner's
     group has read and execute, and others have read only access to the file.

     An ACL that is not a minimum ACL, that is, one that specifies a user or
     group other than the file's owner or owner's group, must contain a mask
     entry:  chacl u::rwx,g::r-x,o::r--,u:guest:r--,m::r-x file1 file2

     You can use the output of ls -D to get the ACL argument to chacl.  To set
     the default and access ACLs on newdir to be the same as on oldir, you
     could type:  chacl -b `ls -dD olddir | cut -d"[" -f2 |  cut -d"/" -f1`
     `ls -dD bardir | cut -d"[" -f2 |  cut -d"/" -f2 | cut -d"]" -f1` newdir
CAUTIONS
     chacl replaces the existing ACL.  To add or delete entries, you must
     first do ls -D to get the existing ACL, and use the output to form the
     arguments to chacl.
