[SOLVED] Get file size after downloading URL content with wget

Issue

I'm trying to write a bash script that will download the contents of a URL (not recursive) and then analyze the file that was downloaded.

If the downloaded file is a text file (i.e index.html) I want to know the size of the file and count the number of characters within that file.

If the file is an image file I just want to know the file size.

Right now I'm working with wget and downloading the contents of the input URL, but the problem is that when I do this inside my script I don't know the file name of the file that was downloaded.

So, the two main question are:

1. How can I get the filename in my script after using wget to perform some analyzing operations on the file?
2. How can I deterime the file type of the downloaded file?

Solution

I did finally manage to solve it.

#!usr/bin/env bash
URL="$1"
FILENAME=$(date +%y-%m-%d-%T) #Set the current date and time as the filename
wget -O "$FILENAME" "$URL"    #Download the content from the URL and set the filename
FILE_INFO=$(file "$FILENAME") #Store the output from the 'file' command

if [[ "$FILE_INFO" == *"text"* ]]
then 
 echo "It's a text file"
elif [[ "$FILE_INFO" == *"image"* ]]
then 
 echo "It's an image"
fi
