To download a file using curl only after a redirect, you can use the -L flag to instruct curl to follow redirects. This flag tells curl to follow any redirects until it reaches the final location of the file you want to download.
For example, you can use the following command to download a file that is redirected to a new location:
curl -L <redirected_url> -o <output_file_name>
In this command, replace <redirected_url> with the URL of the file you want to download, and <output_file_name> with the name you want to save the file as.
By using the -L flag with curl, you can ensure that you download the correct file even after it has been redirected to a new location.

How to set timeout periods for redirects when using Curl to download files?
In order to set a timeout period for redirects when using Curl to download files, you can use the -m or --max-time option followed by the desired timeout period in seconds. Here is an example command:
1
|
curl -L -m 60 -o output_file.zip http://example.com/file.zip
|
In this command, -L is used to follow redirections, -m 60 sets the timeout period to 60 seconds, -o output_file.zip specifies the output file name, and http://example.com/file.zip is the URL of the file to be downloaded.
By setting a timeout period for redirects, you can prevent the Curl command from hanging indefinitely if the server takes too long to respond. Adjust the timeout period as needed based on the specific requirements of your download process.
How to integrate Curl into automated scripts for downloading files after redirects efficiently?
To integrate Curl into automated scripts for downloading files after redirects efficiently, you can follow these steps:
- Install Curl if you haven't already. You can download the latest version of Curl from the official website or use package managers like Homebrew on macOS or apt-get on Linux.
- Create a new script file (e.g., download_files.sh) and add the following code:
1 2 3 4 5 6 |
#!/bin/bash URL="https://example.com/download/file" DESTINATION="~/Downloads" curl -LOJ "$URL" -o "$DESTINATION" |
- Make the script executable by running the following command in the terminal:
1
|
chmod +x download_files.sh
|
- Run the script to download files after redirects efficiently.
This script uses the following Curl options:
- -L option to follow redirects
- -O option to save the downloaded file with the same name as in the remote server
- -J option to specify that the remote server supports content-disposition headers for file names
- -o option to specify the destination directory for the downloaded file
By following these steps, you can efficiently integrate Curl into automated scripts for downloading files after redirects.
What is the Curl command for downloading a file after a redirect?
To download a file after a redirect using the Curl command, you can use the following command:
1
|
curl -L -O <URL>
|
In this command, the "-L" flag tells Curl to follow any redirects, and the "-O" flag tells it to save the downloaded file with the same name as the original file.
For example, if you want to download a file from the URL "http://example.com/file.zip" after a redirect, you would use the following command:
1
|
curl -L -O http://example.com/file.zip
|
How to automatically resume interrupted downloads after a redirect using Curl?
To automatically resume interrupted downloads after a redirect using Curl, you can use the following command:
1
|
curl -L -C - -O http://example.com/file.zip
|
This command includes the -L flag, which tells Curl to follow redirects, and the -C - flag, which enables automatic resume of interrupted downloads.
This will allow Curl to resume a download if it was interrupted due to a redirect, without having to manually restart the download from the beginning.
