Combining wget/curl with Shell Script
By combining wget or curl with a shell script, it's possible to catch the file name of the downloaded file automatically. Here's an example:

url=""
filename=$(basename "$url")
wget -O "$filename" "$url"
In this example, the filename is extracted from the URL using the basename command. Then, the wget command is used to download the file. By using the filename variable, the user can catch the file name and save it with the original name. The same can be done with curl:
#!/bin/bash
url=""
filename=$(basename "$url")
curl -o "$filename" "$url"
Catching the file name of downloaded files using wget and curl commands in a shell script is straightforward. By using the -O or -o option and specifying the name of the output file, it's possible to save the file with the original name. By combining wget or curl with a shell script, it's possible to catch the file name automatically. In summary:
- wget and curl support options for specifying the name of the output file
- By specifying the output file name, it's possible to save the file with the original name
- Combining wget or curl with a shell script allows for automatic file name catching
