linux shell 99乘法表

好的,下面是Linux shell实现的99乘法表:
```
for i in `seq 9`
do
for j in `seq 9`
do
if [ $j -le $i ]
then
let "mul=i*j"
echo -n "$j*$i=$mul "
fi
done
echo ""
done
```
请注意,这段代码可以在Linux系统的命令行中直接执行,也可以将其保存为一个脚本文件再执行。

linuxshell九九乘法表
以下是 Linux Shell 的九九乘法表:
```
#!/bin/bash
for i in {1..9}
do
for j in {1..9}
do
let "result=$i*$j"
echo -n "$i*$j=$result "
done
echo ""
done
```
运行结果如下:
```
1*1=1 1*2=2 1*3=3 1*4=4 1*5=5 1*6=6 1*7=7 1*8=8 1*9=9
2*1=2 2*2=4 2*3=6 2*4=8 2*5=10 2*6=12 2*7=14 2*8=16 2*9=18
3*1=3 3*2=6 3*3=9 3*4=12 3*5=15 3*6=18 3*7=21 3*8=24 3*9=27
4*1=4 4*2=8 4*3=12 4*4=16 4*5=20 4*6=24 4*7=28 4*8=32 4*9=36
5*1=5 5*2=10 5*3=15 5*4=20 5*5=25 5*6=30 5*7=35 5*8=40 5*9=45
6*1=6 6*2=12 6*3=18 6*4=24 6*5=30 6*6=36 6*7=42 6*8=48 6*9=54
7*1=7 7*2=14 7*3=21 7*4=28 7*5=35 7*6=42 7*7=49 7*8=56 7*9=63
8*1=8 8*2=16 8*3=24 8*4=32 8*5=40 8*6=48 8*7=56 8*8=64 8*9=72
9*1=9 9*2=18 9*3=27 9*4=36 9*5=45 9*6=54 9*7=63 9*8=72 9*9=81
```
Linuxshell实现九九乘法表
以下是在 Linux shell 中实现打印九九乘法表的代码:
```shell
#!/bin/bash
for i in {1..9}
do
for j in $(seq 1 $i)
do
echo -n "$j * $i = $((i*j)) "
done
echo ""
done
```
将以上代码保存到一个文件中,比如 `multiplication_table.sh`,然后在终端中运行以下命令即可执行:
```
bash multiplication_table.sh
```
输出结果为:
```
1 * 1 = 1
1 * 2 = 2 2 * 2 = 4
1 * 3 = 3 2 * 3 = 6 3 * 3 = 9
1 * 4 = 4 2 * 4 = 8 3 * 4 = 12 4 * 4 = 16
1 * 5 = 5 2 * 5 = 10 3 * 5 = 15 4 * 5 = 20 5 * 5 = 25
1 * 6 = 6 2 * 6 = 12 3 * 6 = 18 4 * 6 = 24 5 * 6 = 30 6 * 6 = 36
1 * 7 = 7 2 * 7 = 14 3 * 7 = 21 4 * 7 = 28 5 * 7 = 35 6 * 7 = 42 7 * 7 = 49
1 * 8 = 8 2 * 8 = 16 3 * 8 = 24 4 * 8 = 32 5 * 8 = 40 6 * 8 = 48 7 * 8 = 56 8 * 8 = 64
1 * 9 = 9 2 * 9 = 18 3 * 9 = 27 4 * 9 = 36 5 * 9 = 45 6 * 9 = 54 7 * 9 = 63 8 * 9 = 72 9 * 9 = 81
```
