r - Using bash to transform a numeric sequence -

here vector of numbers have ascend (it called t8_)

2 7 8 9 11 15 34 91 91 92 94 

the problem number happen 2 times - don't want remove them have become 2 numbers unique , not floating point. thought @ first iterating through vector

the next vector be

2 7 8 9 11 15 34 91 92 92 94 

then same process again

when vector be

2 7 8 9 11 15 34 91 92 93 94 

for example works

#!/bin/bash  while read -a vec;         # int_min bash: 32-bit bash supports 64-bit integers.         min=$((-1<<63))          ((i = 0; < ${#vec[@]}; i++));                 (( min = vec[i] = vec[i] > min ? vec[i] : min + 1 ))         done         echo "${vec[@]}" done ### 

the problem not real vector looks https://www.dropbox.com/s/vp67eiw4ns9rr07/num?dl=0.

when un.sh < vec don't output in specific instance. tell me why?

i can't why shell code isn't working you, can offer perl solution works fine data

use strict; use warnings; use 5.010; use autodie;  @numbers = split ' ', {     open $fh, '<', 'num';     local $/;     <$fh>; };  $i ( 1 .. $#numbers ) {   ++$numbers[$i] if $numbers[$i] == $numbers[$i-1]; }  "@numbers";
