1:实现shell脚本中循环调用函数
#!/bin/bash output(){
for(( num1=; num1 <= ; num1++ ))
do
echo -n "$num1 "
done
} let "num2=1"
while [ "$num2" -le ]
do
output
echo
let "num2=num2+1"
done
实现结果:
2:判断系统是否存在此文件
#!/bin/bash
#文件系统相关测试 fpath="/etcc/passwd"
if [ -e $fpath ];then
echo File exits;
else
echo Does not exits
fi
