Not with a single input source piped into something. Note that you open and read test.txt twice in your above construct. You could do (but this is far from being smart nor efficient)


Code:
cat <(docker image ls | head -n1) <(docker image ls | tail -n+2 | sort -Vrk5 )

You might feel inspired to use tee to split the input into different branches of execution, but it'd be difficult to predict the resultant order of lines. This clumsy approach seems to do it on my system
Code:
docker image ls | tee >(head -n1) >(tail -n+2 | sort -rk5) > /dev/null

, but, again, this is far from using common sense.

mcx convert(1)							  USER COMMANDS 						    mcx convert(1)

  NAME
      mcx convert - convert between mcx storage types

  SYNOPSIS
      mcx convert <matrix-file-in> <matrix-file-out>
      mcx convert [--write-binary] --cone-to-stack <cat-file-in> <cat-file-out>
      mcx convert [--write-binary] --stack-to-cone <cat-file-in> <cat-file-out>

      mcxconvert  is  not  in  actual fact a program. This manual page documents the behaviour and options of the mcx program when invoked in mode
      convert. The options -h, --apropos, --version, -set, --nop, -progress <num> are accessible in all mcx modes. They are described in  the  mcx
      manual page.

      mcx  convert  [--cone-to-stack  (transform  cone	file to stack file)] [--stack-to-cone (transform stack file to cone file)] [--write-binary
      (output native binary format)] [--cat (read and write cat format)] [-cat-max <num> (limit the stack conversion to <num> matrices)]

      In the two-argument invocation without additional arguments, mcx convert converts from the format found in the first file to the other  for-
      mat, i.e.  from native interchange to native binary format or the other way around. When querying with the -q option, mcx{convert} will out-
      put a one-line synopsis describing the matrix in the argument. The --cone-to-stack and --stack-to-cone options convert between the two types
      of concatenated output provided by mclcm.

  DESCRIPTION
      The  mcl	libraries make extensive use of matrices. Matrices are used to encode graphs, matrices and clusterings.  They can be stored either
      in interchange or in binary format. The latter is somewhat more efficient in storage and much faster in both reading and	writing,  but  the
      default is interchange format.

      The  mcl input routines recognize the type of storage they are dealing with. If you want to convert a matrix to the other storage type, sim-
      ply specify the file name of the matrix you want to convert.  mcx convert will recognize its type, and write the	other  type  to  the  file
      specified as the second argument.

  OPTIONS
      --cone-to-stack (transform cone file to stack file)
	This option requires two trailing options, the names of respectively the source cone file and the target stack file.

      --stack-to-cone (transform stack file to cone file)
	This option requires two trailing options, the names of respectively the source stack file and the target cone file.

      --cat (read and write cat format)

      -cat-max <num> (limit the stack conversion to <num> matrices)

      --write-binary (output native binary format)
	This option is only useful with either of the options --cone-to-stack, --stack-to-cone, or --cat.
