How to save wget downloads to a specific file or directory

Explicit control over where wget stores downloaded content keeps working directories clean and reproducible. Specifying output files or directories ensures logs, archives, and temporary artifacts land in predictable locations that align with automation, backup routines, and configuration management.

By default, wget derives the local file name from the URL path and writes it into the current working directory. The –output-document (-O) option replaces both the file name and the path, while –directory-prefix (-P) changes only the directory component and preserves the server-provided file name. These flags operate purely on the local filesystem, so HTTP semantics, headers, and responses remain unchanged.

Incorrectly chosen output paths can overwrite critical files, leak data into world-readable locations, or exhaust capacity on small partitions. Using absolute paths, verifying directory ownership, and separating scratch space from long-term storage lowers those risks and makes automated downloads safer to run under dedicated system accounts.

1. Save a single URL response into a specific file path using the –output-document option.

   $ wget --output-document=/tmp/example.html https://example.com/
   --2025-12-08 09:15:00--  https://example.com/
   Resolving example.com (example.com)... 93.184.216.34
   Connecting to example.com (example.com)|93.184.216.34|:443... connected.
   HTTP request sent, awaiting response... 200 OK
   Length: 1256 (1.2K) [text/html]
   Saving to: ‘/tmp/example.html’
   
   /tmp/example.html     100%      1.23K  --.-KB/s    in 0s
   
   2025-12-08 09:15:00 (15.0 MB/s) - ‘/tmp/example.html’ saved [1256/1256]

   Passing an absolute path such as /tmp/example.html decouples the output location from the current working directory and simplifies later verification.

2. Create a dedicated directory for grouped wget downloads under the home directory.

   $ mkdir -p ~/downloads/wget

   The -p flag ensures creation of the full path, so a directory like /home/user/downloads/wget appears without errors even if intermediate directories already exist.

3. Download a file into the dedicated directory while retaining the original file name by using –directory-prefix.

   $ wget --directory-prefix=~/downloads/wget https://example.com/files/archive.tar.gz
   --2025-12-08 09:17:00--  https://example.com/files/archive.tar.gz
   Resolving example.com (example.com)... 93.184.216.34
   Connecting to example.com (example.com)|93.184.216.34|:443... connected.
   HTTP request sent, awaiting response... 200 OK
   Length: 1351680 (1.3M) [application/x-tar]
   Saving to: ‘/home/user/downloads/wget/archive.tar.gz’
   
   archive.tar.gz        100%    1.29M  12.0MB/s    in 0.1s
   
   2025-12-08 09:17:00 (12.0 MB/s) - ‘/home/user/downloads/wget/archive.tar.gz’ saved [1351680/1351680]

   –directory-prefix changes only the directory while preserving the remote file name, which keeps on-disk names aligned with upstream artifacts.

4. Store a URL response under a custom name inside the dedicated directory by passing a full path to –output-document.

   $ wget --output-document=~/downloads/wget/index-example.html https://example.com/
   --2025-12-08 09:18:00--  https://example.com/
   Resolving example.com (example.com)... 93.184.216.34
   Connecting to example.com (example.com)|93.184.216.34|:443... connected.
   HTTP request sent, awaiting response... 200 OK
   Length: 1256 (1.2K) [text/html]
   Saving to: ‘/home/user/downloads/wget/index-example.html’
   
   index-example.html    100%      1.23K  --.-KB/s    in 0s
   
   2025-12-08 09:18:00 (15.0 MB/s) - ‘/home/user/downloads/wget/index-example.html’ saved [1256/1256]

   –output-document overwrites any existing file at the target path, so directing output to a critical file such as /etc/hosts or a production configuration can silently destroy important data.

5. Confirm that the downloaded files exist in the expected locations and show reasonable sizes using ls with long listing.

   $ ls -lh /tmp/example.html ~/downloads/wget
   -rw-r--r-- 1 user user 1.3K Dec  8 09:15 /tmp/example.html
   /home/user/downloads/wget:
   total 2.6M
   -rw-r--r-- 1 user user 1.3M Dec  8 09:17 archive.tar.gz
   -rw-r--r-- 1 user user 1.3K Dec  8 09:18 index-example.html

   Entries with nonzero sizes, recent timestamps, and paths such as /tmp/example.html and /home/user/downloads/wget confirm that output control flags were applied as intended.
