#/bin/bash
for i in 1 2 3 4 5 6 7 8 9
do
echo "the number of $i computer is "
ping -c 1 192.168.0.$i
done
9.如果test.log的大小大于0，那么将/opt目录下的*.tar.gz文件
#/bin/sh
a=2
while name="test.log"
do
sleep 1
b=$(ls -l $name | awk '{print $5}')
if test $b -ge $a
#then echo "OK"
then `cp /opt/*.tar.gz .`
exit 0
fi
done
10.打印读取的内容，为下面的例子做准备
#/bin/bash
while read name
do
echo $name
done
11.从0.sh中读取内容并打印
#/bin/bash
while read line
do
echo $line
done < 0.sh
12.读取a.c中的内容并做加1运算
#/bin/bash
test -e a.c
while read line
do
a=$(($line+1))
done < a.c
echo $a
13.普通无参数函数
#/bin/bash
p ()
{
echo "hello"
}
p
14.给函数传递参数
#/bin/bash
p_num ()
{
num=$1
echo $num
}
for n in $@
do
p_num $n
done
15.创建文件夹
#/bin/bash
while :
do
echo "please input file's name:"
read a
if test -e /root/$a
then
echo "the file is existing Please input new file name:"
else
mkdir $a
echo "you aye sussesful!"
break
fi
done
16.获取本机IP地址
#/bin/bash
ifconfig | grep "inet addr:" | awk '{ print $2 }'| sed 's/addr://g'
17.查找最大文件
#/bin/bash
a=0
for name in *.*
do
b=$(ls -l $name | awk '{print $5}')
if test $b -ge $a
then a=$b
namemax=$name
fi
done
echo "the max file is $namemax"
18.查找当前网段内IP用户，重定向到ip.txt文件中
#/bin/bash
a=1
while :
