The above is sorted by a custom fixed array, the following is the user-defined input array to sort.

#/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
