This looks like a binary format file when viewed with vi. Control codes are displayed as ^X . See "man ascii" for a table of these codes. For example "^@" is a null character (Hex 00).

Try visually comparing the output of:
strings filename | pg
cat -v filename | pg

If the ^X characters disappear in the "strings" version, the file contains control codes rather than actual "^" characters.

Accurate processing of a binary format file with text file programs such as "vi" , "sed" and "awk" is unlikely to produce a useful conversion. Your will need a proper program. If you just want to see an overview of the contents then "strings" will suffice.

rpccp_remove_member

remove member(1m)														 remove member(1m)

NAME

       remove member - Removes a specified member from a group

SYNOPSIS

       rpccp remove member  group-entry-name -m member [-s syntax]

OPTIONS

       Declares  the  entry  name  of the group member to be removed (required).  Indicates the name syntax of the entry name (optional). The only
       value for this option is the dce name syntax, which is the default name syntax. Until an alternative name syntax becomes available,  speci-
       fying the -s option is unnecessary.

ARGUMENTS

       Indicates  the  name  of  the  target group.  For an entry in the local cell, you can omit the cell name and specify only the cell-relative
       name.

DESCRIPTION

       The remove member command removes a specified member from a specified group.

   Privilege Required
       You need read permission and write permission to the CDS object entry (the target group entry).

NOTE

       This command is replaced at Revision 1.1 by the dcecp command and may not be provided in future releases of DCE.

EXAMPLES

       The following commands run RPCCP and remove the member /.:/LandS/anthro/Cal_host_2 from the group  /.:/LandS/dept/Calendar_group:  $  rpccp
       rpccp>  remove  member	  >  -m /.:/LandS/anthro/Cal_host_2   > /.:/LandS/anthro/Calendar_group The following command removes the member
       /.:/LandS/anthro/Cal_host_3 from the group /.:/LandS/anthro/Calendar_group: $ rpccp remove member   > -m /.:/LandS/anthro/Cal_host_3    >
       /.:/LandS/anthro/Calendar_group
