写一个shell脚本，打印打印九九乘法表，脚本如下：
#!/bin/bash for ((j=1;j<=9;j++)) do for ((i=1;i<=j;i++)) do echo -e -n "${i}X${j}=$[${i}*${j}]\t" done echo done

|-------------------|------------------------------------------------------------------------------------------------------------------------| | 1 2 3 4 5 6 7 8 9 | #!/bin/bash for ((j=1;j<=9;j++)) do for ((i=1;i<=j;i++)) do echo -e -n "${i}X${j}=$[${i}*${j}]\t" done echo done |
