bash script rename input file while copying

Question

I am running my bash script with a file as the input file:

./myscript.sh anyfilename.txt

and then here is the script:

#!/bin/bash

input_file=$1
dest_dir="./destination"
mkdir -p "$dest_dir"
cp "$input_file" "$dest_dir"

when I run it, it copies the file to the destination directory using the same name as it is passed to the bash parameter, anyfilename.txt.

Question:

how can I copy the input file into the destination directory by renaming it always as myfile.txt?

Answer 1

You can use command like:

#!/bin/bash
input_file=$1
new_file=$2
dest_dir="./destination"
mkdir -p "$dest_dir"
cp "$input_file" "${dest_dir}/${new_file}"

and run the script like:

./myscript.sh anyfilename.txt myfile.txt
