How do I sort an array in bash?












2














I have an array with h4 h5 h1 h2 h3 in it and I would like to sort it according to the numbers, but don't know how. What is the best way to do this?



edit1: I would also like to sort an array via the numbers containing different letters, for example s4 h5 q1 h2 g3.

Try this,



Just print, sort and store the values in the same array name.



ary=(h4 h5 h1 h2 h3)

ary=(`printf '%sn' "${ary[@]}"|sort`)



echo ${ary[@]}

h1 h2 h3 h4 h5

    No need to use tr; shell's "Parameter Expansion" with an adequate IFS (in a subshell) should suffice. Try 



    $ ARR=(h4 h5 h1 h2 h3)
    
$ SA=( $(IFS=$'n'; echo "${ARR[*]}" | sort) )
    
$ BRR=(s4 h5 q1 h2 g3)
    
$ SB=( $(IFS=$'n'; echo "${BRR[*]}" | sort -k1.2) )
    
$ echo "${SB[*]}" 
    
q1 h2 g3 s4 h5

    Lets take an array A as



    A=(h4 h5 h1 h2 h3)


    Now, the problem with the sort command is that it sorts elements in different line and can't sort elements in the same line. So, the workaround is to transform the array into an element per line and sort with sort and put them in an array which is actually sorted, that is,



    B=(`echo ${A[@]} | tr " " "n" | sort`)


    Now, B is the sorted array. Here, tr transforms space into a newline

Something like that: I cannot achieve that with regular card, I also tried Card with States by OKViz but also unable to see both values. In KPI visual - I dont like the word "Goal", it will confuse end users. Are there any cards or other visuals that would do the job?
