Question

Why am I getting error below?

Below is my vim script I am running. I can't see the error, please help:

#!/bin/bash

count =1

echo "start of the program"

while [ $count -le 10 ]

do

echo "Loop #$count"

sleep 10

count=$[ count + 1]

done

echo "end of the program"

Linux is very sensitive langauage and you alweays have to care about the spaces or any other tiny errors you may get when executing a program.

Here in this program, yoiu had this error because of an additional space in line 2

count =1

This is invalid

And shoud be change to

count=1

Which fixes your problem.

#!/bin/bash

count=1

echo "start of the program"

while [ $count -le 10 ]

do

echo "Loop #$count"

sleep 10

count=$[ count + 1]

done

echo "end of the program"

Execution of the program:
