* Às vezes, há números ausentes, como 56M neste caso

    

Answer 1

Usando sed :

sed -i -e 's/ /\n/' <(sort -n <(sed -e 'N;s/\n/ /' in.txt))

Explicações:

• As sed -e 'N;s/\n/ /' in.txt partes, juntando cada duas linhas juntas com espaço único
• A parte sort -n , realizando ordenação numérica
• Em seguida, sed -e 's/ /\n/' , estamos dividindo a linha em duas linhas separadas de acordo com o espaço único entre elas.
• O -i gravará as alterações no arquivo de entrada no local, usando -i.bak para fazer um backup do arquivo de entrada primeiro.

Answer 2

awk '/^>/ { printf "%s ",$0; next; } { print; }' file1 | 
    sort -n |
    awk '{ print $1; print $2; }'

    

Answer 3

Você pode usar a Schwartzian transform em Perl para fazer isso:

perl -ne '
   push @A, $_.=<>}{
   print for
    # Schwartzian transform
    map  { $_->[0] }             # recover the line
    sort { $a->[1] <=> $b->[1] } # do the sorting using the key 
    map  { [$_,/_(\d+)M$/m] }    # setup: line(zeroth-indexed) + sorting key(first index)
    @A;                          # operate on elements of array @A
' yourfile

coloque o arquivo em pares de linhas na matriz @A . Então, no eof, realizamos a manobra Schwartzian , "map- > sort- > map". Neste nós carregamos toda a linha + os dados de ordenação ao longo e no último passo da manobra, recuperamos a linha depois de ter sido ordenada. Portanto, para este caso, a chave de classificação é o número antes do M que fica no limite da linha. (Lembre-se que acrescentamos a próxima linha)
