How to Change the Maximum Number of Retries in Wget?
When downloading files using the wget command-line
utility, network instability or server issues can cause downloads to
interrupt. By default, Wget will automatically attempt to resume a
failed download up to 20 times before giving up. This article provides a
quick overview of how to modify this limit using the
--tries option for individual commands, how to configure a
permanent change via the .wgetrc file, and how to set
infinite retries for persistent downloads.
Changing Retries for a Single Command
If you only need to adjust the retry limit for a specific download,
you can use the -t or --tries option directly
in your terminal command. This is ideal for one-off downloads where you
know the server is particularly unstable or, conversely, when you want
it to fail quickly without wasting time.
To set the maximum number of retries to a specific number, use the following syntax:
wget -t 5 https://example.com/file.zip
In this example, Wget will only attempt to connect 5 times before terminating the request. You can also use the full option name:
wget --tries=5 https://example.com/file.zip
Setting Infinite Retries
In scenarios where you are downloading a critical, large file over a highly unreliable connection, you might want Wget to keep trying indefinitely until the download succeeds.
To configure infinite retries, set the value to 0 or
inf:
wget -t 0 https://example.com/large-file.iso
Alternatively, this command achieves the exact same result:
wget --tries=inf https://example.com/large-file.iso
Making the Change Permanent
If you find yourself constantly changing the retry limit, you can
alter Wget’s default behavior permanently by editing the configuration
file. Wget reads settings from a file named .wgetrc located
in your home directory.
- Open the file in a text editor, such as Nano:
nano ~/.wgetrc - Add or modify the
triesline to your preferred number. For example, to set the global default to 10 retries, add:tries = 10 - Save and close the file.
If you want to apply this change globally for all users on a Linux
system, you can edit the system-wide configuration file instead, which
is typically located at /etc/wgetrc.
