How do I print out the byte size of each file in my Bash script?

My current code is like so:

scan.sh:

#!/bin/bash
while IFS= read -r line;
do
 byte = $(stat -c%s "$line");
 echo "$line : $byte";
done< <(ls *.$1)

The output would be like this:

./scan.sh cpp
./scan.sh: line 4: byte: command not found
arraysum.cpp :
./scan.sh: line 4: byte: command not found
countLines.cpp :
./scan.sh: line 4: byte: command not found
createtext.cpp :
./scan.sh: line 4: byte: command not found
multiproc1.cpp :
./scan.sh: line 4: byte: command not found
myWc.cpp :
./scan.sh: line 4: byte: command not found
test.cpp :

Basically my code will take one syntax and will search the directory based on that syntax. The problem is I want it to print out "name of file" + "byte size of file", only I can't seem to get that working.

It should be byte=$(.... -- get rid of the spaces around the = sign.

In the syntax of Bourne-like shells like bash, there must not be any space around the = sign in assignments.

byte=value

Here though, parsing the output of ls is a bad idea.

You can just write it:

#! /bin/sh -
stat -c '%n: %s' -- *."$1"

If you do need a loop, just write it:

#! /bin/zsh -
for file in *.$1; do
 stat -c '%n: %s' -- $file
done

Or if you have to use bash:

#! /bin/bash -
shopt -s failglob
for file in *."$1"; do
 stat -c '%n: %s' -- "$file"
done
