Cannot assign variable in for-loop in shell script

Time：12-27

I tried to assign variable a in for-loop:

#!/bin/bash

for file in `ls`
do
  a = $file
done

But when I run, it gave error:

line 5: a: command not found

Why did it give error? How to assign variable a?

CodePudding user response：

There can be no spaces on both sides of the equal sign when defining variables in the Shell.

It should be:

a=$file

CodePudding user response：

You need remove spaces i.e.

a = $file

must be

a=$file
