Sed $ appending to front, not to the end
I keep trying to append some astrix to the end of a line, but it keeps overwriting at the front of the line.

These are the originals

Code:
Fred Fardbarkle:674-843-1385:20 Parak Lane, Duluth, MN 23850:4/12/23:780900
Fred Fardbarkle:674-843-1385:20 Parak Lane, Duluth, MN 23850:4/12/23:780900

Here's the output

Code:
***d Fardbarkle:674-843-1385:20 Parak Lane, Duluth, MN 23850:4/12/23:780900
***d Fardbarkle:674-843-1385:20 Parak Lane, Duluth, MN 23850:4/12/23:780900

It's supposed to look like this
Code:
Fred Fardbarkle:674-843-1385:20 Parak Lane, Duluth, MN 23850:4/12/23:780900***
Fred Fardbarkle:674-843-1385:20 Parak Lane, Duluth, MN 23850:4/12/23:780900***

My code looks like this
Code:
sed '/^Fred/s/$/***/' inputfile

Does that make any sense at all? Is there any situation where it would do that?

If you think it should work, please tell me, so that maybe I can go about installing a different version of sed.

Figured it out.

apparently sed needs a . before the $
the proper code looks like this

Code:
sed '/^Fred/s/.$/***/' inputfile

__gnu_parallel::restrictedboundedconcurrentqueue

__gnu_parallel::RestrictedBoundedConcurrentQueue< T >(3cxx)			       __gnu_parallel::RestrictedBoundedConcurrentQueue< T >(3cxx)

NAME

       __gnu_parallel::RestrictedBoundedConcurrentQueue< T > -

SYNOPSIS

   Public Member Functions
       bool pop_back (T &t)
       bool pop_front (T &t)
       void push_front (const T &t)
       RestrictedBoundedConcurrentQueue (sequence_index_t max_size)
       ~RestrictedBoundedConcurrentQueue ()

Detailed Description
   template<typename T>class __gnu_parallel::RestrictedBoundedConcurrentQueue< T >
       Double-ended queue of bounded size, allowing lock-free atomic access. push_front() and pop_front() must not be called concurrently to each
       other, while pop_back() can be called concurrently at all times. empty(), size(), and top() are intentionally not provided. Calling them
       would not make sense in a concurrent setting.

       Parameters:
	   T Contained element type.

       Definition at line 52 of file queue.h.

Constructor &; Destructor Documentation
   template<typename T> __gnu_parallel::RestrictedBoundedConcurrentQueue< T >::RestrictedBoundedConcurrentQueue (sequence_index_tmax_size)
       [inline]
       Constructor. Not to be called concurrent, of course. Parameters:
	   max_size Maximal number of elements to be contained.

Member Function Documentation
   template<typename T> bool __gnu_parallel::RestrictedBoundedConcurrentQueue< T >::pop_back (T &t) [inline]
       Pops one element from the queue at the front end. Must not be called concurrently with pop_front().
