The array that is written above is the array sort that was previously defined in the code, and the following is the sort of array that the user customized during the execution.

#/bin/basha= ' expr $# + 1 ' #expr是一个计算操作, $ #是参数个数, $#+1 is because there are no storage parameters. Temp=for ((i=1;i< $a; i++)) {b[$i]=$1shift 1}for (i=1 ;i< $a; i++) {for ((j=i;j< $a; j + +)) {x=${b[$i]}if test $x-ge ${b[$j]}thentemp=${b[$i]}b[i]=${b[$j]}b[j]= $temp # Quite with bubble sort fi}}for ((k=1;k< $a; k++)) {echo-n ${b[$k]} "" #不换行显示}echo
