Question

I have written a small program to get the list of all files in a directory and concatenating them to a single string variable. Here’s the code

#!/bin/bash
dir ="/home/user/myfolder/abc"
res=" "

for f in $( ls $dir  ); do
    res="$res $f"
done

echo $res

However I am getting the following error

dir: cannot access =/home/user/myfolder/abc: No such file or directory

I have set all the required permissions, whats the solution?

Answer 1

Remove the space between the assignment:

#!/bin/bash
dir ="/home/user/myfolder/abc"

Do this:

#!/bin/bash
dir="/home/user/myfolder/abc"

Each language has its own syntax, and bash scripting requires no spaces between left_value=right_value during assignments; as you see, it’s simply a matter of syntax.
