Question How to archive old files from the recently added 10 files?
Hi there, I am very new to unix and having trouble with a fairly simple statement:

Code:
 
cd /user
ls -t -c1 | sed -ne '11,$p' | mv xargs archive/


What I want the code to do is sort all files in a directory by timestamp, select all of the files after the 10th file, and then move those files to an /archive folder.

When I execute this statement it throws a "file not found" error, is there any obvious reason why this isnt working?

Thanks

ar86

ar86(1) 						      General Commands Manual							   ar86(1)

NAME

       ar86 - Create, modify, and extract from archive file

SYNOPSIS

       ar86 operation archive [file...]

       ar86 positional-op member archive [file...]

DESCRIPTION

       The ar86 program is used to create, examine and modify archive files produced by the Dev86/ELKS toolchain.

OPTIONS

       The  ar86  command  requires  that  the	operation  to  be  performed  on the archive be specified as the first option. If the operation is
       positional then the next option is the archive member marking the position. This is followed by the archive file name and any list of  file
       names.

   Operations
       One of the following operations can be specified

       d      delete the listed files from the archive.

       m      move the named files. By default files are moved to the end of the archive unless a positional modifier is present.

       p      print  the contents of archive members to standard out. If a file list is included only those members are printed. If the v modifier
	      is present each file's contents are preceeded by a new line, a line with the string member, a space character, the member name,  and
	      two following newlines.

       q      quickly  add  the  files to the end of the archive without checking to see if they already exist in the archive. This operation will
	      ignore any positional modifiers. Creates the archive file if it does not exist.

       r      replace archive members with the files listed. If the file name is not present in the archive it is added to the end of the  archive
	      (or to any explicitly specified position). Creates the archive file if it does not exist.

       t      table;  list  the  file  names  of  archive  members. If a file list is present only those files that are present in the archive are
	      listed.  The v modifier prints member attributes.

       x      extract the named files from the archive into the current directory. If no files are specified  all  the	archive  members  will	be
	      extracted.

   Modifiers
       The following modifiers may be used with the operations

       o      original time stamps from the archive are preserved for extracted files when possible.

       s      symbol  update;  this option may be used by itself to force an update to the symbol definition section of the archive (the __.SYMDEF
	      member). If any files are specified they will be replaced as if the r operation had been specified. If no symbol definition  section
	      exists one is created. This option will also creates the archive file if it does not exist.

       u      update files in the archive during a r (replace) operation. The files are added to the archive in exactly the same manner as replace
	      except that an existing archive member will be retained (in its original position) if it has a modified more recently than the  file
	      being  added.  Note that this modifier acts as if a r operation has been specified (even it has not), and will actually override any
	      other previously specified operation.

       v      verbose; print additional diagnostic messages while processing the archive.

   Positional Modifiers
       The following modifiers specify where in the archive files are moved to or added. If any of these modifiers are specified then  the  second
       option to ar86 must be the name of an archive member.

       a      after; files are placed after the specified archive member.

       b      before; files are placed before the specified archive member.

       i      same as b.

EXAMPLES

       To see the contents of an archive

	      ar86 tv libfile.a

       To add some files to an archive

	      ar86 r libfile.a file1.o file2.o

       to add some files after a member named mem.o and to update the symbol table

	      ar86 rsa mem.o libfile.a file1.o file2.o

BUGS

       A l modifier will be accepted but ignored.

RESTRICTIONS

       This command is intended for use only with object files created using the Dev86/ELKS toolchain.
