Ubuntu uses SH to not execute script file resolution

Source: Internet
Author: User

Just started learning the Linux shell language recently

It's the private dish of Brother Bird. There are two ways to execute a shell script:

1. Set execution properties: chmod 755 file

Execute (if already in current directory):./file

2. Use: Sh File execution

. But the Ubuntu 11.10 installed in VMware is not performing

#!/bin/bash
declare-i S for
((i = 1; I <= 100;i = i+1))
doing 
	s=s+i
doing
echo "The Count is ==& Gt $s "

Occurs when executed with the second method:

Test04_for.sh:1: Declare:not found
Test04_for.sh:3: Syntax Error:bad for loop variable


Baidu down the Internet, the solution:

In the terminal, enter:

sudo dpkg-reconfigure Dash

Then select NO in the interface that appears

And then you can run it correctly.
