shell循环学习03

#!/bin/bash
clear

for((i=1;i<100;i++))
for
        do
        if((i%3==0))
        then
        echo $i
        continue
        fi
        done
2.使用`seq 100`
#!/bin/bash
clear

for i in `seq 100`
        do
        if((i%3==0))
        then
        echo $i
        continue
        fi
        done
3.使用while
#!/bin/bash
limit=5
i=0
while [ $i -le $limit ]
do
echo -e "##################  This is loop $i time No audit ######################"
i=$(($i+1))
done
~

#!/bin/sh
#filename:2.sh
b=9
e=15
tmpb=$b
while [ $tmpb -le $e ]
do
echo $tmpb
#tmpb=`expr $tmpb + 1` //ok
tmpb=$(expr $tmpb + 1)
done

4.使用数组

1. #!/bin/sh
3. a1="11 12 13"
4. a2="21 22 23"
5. a3="31 32 33"
7. for index in a1 a2 a3
8. do
9.   eval d1=\$$index
10.   for d2 in $d1
11.   do
12.     echo $d2
13.   done
14. done
16. #----- eof -----#

5. 调用文件中的变量

cat var.tmp | while read user
do

echo $user

done
