I want to download an image accessible from this link: https://www.python.org/static/apple-touch-icon-144x144-precomposed.png into my local system. Now, I'm aware that the curl command can be used to download remote files through the terminal. So, I entered the following in my terminal in order to download the image into my local system:
curl https://www.python.org/static/apple-touch-icon-144x144-precomposed.png
However, this doesn't seem to work, so obviously there is some other way to download images from the Internet using curl. What is the correct way to download images using this command?
curl without any options will perform a GET request. It will simply return the data from the URI specified. Not retrieve the file itself to your local machine.
When you do,
$ curl https://www.python.org/static/apple-touch-icon-144x144-precomposed.png
You will receive binary data:
|�>�$! <R�HP#T*�Pm�Z��jU֖��ZP+UAUQ#�
��{X\� K���>0c�yF[i�}4�!�V̧�H_�)nO#�;I��vg^_ ��-Hm$$N0.
���%Y[�L�U3�_^9��P�T�0'u8�l�4 ...
In order to save this, you can use:
$ curl https://www.python.org/static/apple-touch-icon-144x144-precomposed.png > image.png
to store that raw image data inside of a file.
An easier way though, is just to use wget.
$ wget https://www.python.org/static/apple-touch-icon-144x144-precomposed.png
$ ls
.

For those who don't have nor want to install wget, curl -O (capital "o", not a zero) will do the same thing as wget. E.g. my old netbook doesn't have wget, and is a 2.68 MB install that I don't need.
curl -O https://www.python.org/static/apple-touch-icon-144x144-precomposed.png
If you want to keep the original name — use uppercase -O
curl -O https://www.python.org/static/apple-touch-icon-144x144-precomposed.png
If you want to save remote file with a different name — use lowercase -o
curl -o myPic.png https://www.python.org/static/apple-touch-icon-144x144-precomposed.png
Create a new file called files.txt and paste the URLs one per line. Then run the following command.
xargs -n 1 curl -O < files.txt

For ones who got permission denied for saving operation, here is the command that worked for me:
$ curl https://www.python.org/static/apple-touch-icon-144x144-precomposed.png --output py.png
try this
$ curl https://www.python.org/static/apple-touch-icon-144x144-precomposed.png > precomposed.png

I am trying to run this line on a linux machine:
curl --request GET \ --url 'https://www.tenable.com/downloads/api/v2/pages/nessus/files/Nessus-10.4.2-ubuntu1404_amd64.deb' \ --output 'nessus.deb'
but I am getting this error:
curl: (3) Host name ' --url' contains bad letter
Warning: Binary output can mess up your terminal. Use "--output -" to tell
Warning: curl to output it to your terminal anyway, or consider "--output
Warning: " to save to a file.
I ended up using: wget https://www.tenable.com/downloads/api/v2/pages/nessus/files/Nessus-10.4.2-ubuntu1404_amd64.deb
but it seems I should not have done it this way because now the subsequent line I want to run isn't working: dpkg -i nessus.deb
The output for the curl was 'nessus.deb'. So to install you had to use 'dpkg -i nessus.deb'.
However, because you used wget, it did not create the output name, but just saved 'INSERTFILENAMEHERE'. So to install it, you would use:
'dpkg -i *INSERTFILENAMEHERE*'
For example, you would have put in
'wget https://www.tenable.com/downloads/api/v2/pages/nessus/files/Nessus-10.4.2-ubuntu1404_amd64.deb'
Then it would say something like
''Nessus.deb' saved'
So you would then put in.
'dpkg -i Nessus.deb'
And it would install the package. In short, the reason why the line was not working was because the file was there, but the name did not match.
I am using wget on linux system like :
wget -r -nH --cut-dirs=3 --user="username" --password="password" --no-parent https://artifactory.company.com/nestetedlink1/nested_link2/directory_to_download -P home/user
Using this I get only files saved in the path no unwanted directory component from url: home/user/file_1, file_2
Is this possible to do the same functionality using curl command?
if I have to stick with WGET how to pass the api key I tried the below with --header='X-Auth-Token:, am I doing something wrong :
wget -r -nH --cut-dirs=3 --header='X-Auth-Token: <api_key>' --no-parent https://artifactory.company.com/nestetedlink1/nested_link2/directory_to_download -P home/user
How to insert api Key instead of username and password in wget?
wget --header='X-JFrog-Art-Api:api-key' https://artifactoryurl/filename.gz
I'm trying to use wget to elegantly & politely download all the pdfs from a website. The pdfs live in various sub-directories under the starting URL. It appears that the -A pdf option is conflicting with the -r option. But I'm not a wget expert! This command:
wget -nd -np -r site/path
faithfully traverses the entire site downloading everything downstream of path (not polite!). This command:
wget -nd -np -r -A pdf site/path
finishes immediately having downloaded nothing. Running that same command in debug mode:
wget -nd -np -r -A pdf -d site/path
reveals that the sub-directories are ignored with the debug message:
Deciding whether to enqueue "https://site/path/subdir1". https://site/path/subdir1 (subdir1) does not match acc/rej rules. Decided NOT to load it.
I think this means that the sub directories did not satisfy the "pdf" filter and were excluded. Is there a way to get wget to recurse into sub directories (of random depth) and only download pdfs (into a single local dir)? Or does wget need to download everything and then I need to manually filter for pdfs afterward?
UPDATE: thanks to everyone for their ideas. The solution was to use a two step approach including a modified version of this: http://mindspill.net/computing/linux-notes/generate-list-of-urls-using-wget/

Try this
1)the “-l” switch specifies to wget to go one level down from the primary URL specified. You could obviously switch that to how ever many levels down in the links you want to follow.
wget -r -l1 -A.pdf http://www.example.com/page-with-pdfs.htm
refer man wget for more details
if the above doesn't work,try this
verify that the TOS of the web site permit to crawl it. Then, one solution is :
mech-dump --links 'http://example.com' |
grep pdf$ |
sed 's/\s+/%20/g' |
xargs -I% wget http://example.com/%
The mech-dump command comes with Perl's module WWW::Mechanize (libwww-mechanize-perl package on debian & debian likes distros
for installing mech-dump
sudo apt-get update -y
sudo apt-get install -y libwww-mechanize-shell-perl
github repo https://github.com/libwww-perl/WWW-Mechanize
I haven't tested this, but you cans still give a try, what i think is you still need to find a way to get all URLs of a website and pipe to any of the solutions I have given.
You will need to have wget and lynx installed:
sudo apt-get install wget lynx
Prepare a script name it however you want for this example pdflinkextractor
#!/bin/bash
WEBSITE="$1"
echo "Getting link list..."
lynx -cache=0 -dump -listonly "$WEBSITE" | grep ".*\.pdf$" | awk '{print $2}' | tee pdflinks.txt
echo "Downloading..."
wget -P pdflinkextractor_files/ -i pdflinks.txt
to run the file
chmod 700 pdfextractor
$ ./pdflinkextractor http://www.pdfscripting.com/public/Free-Sample-PDF-Files-with-scripts.cfm
I've been trying to download all the zip files on this website to an EC2 server. However, it is not recognizing the links and thus not downloading anything. I think it's because the shtml file requires that SSI be enabled and that's somehow causing a problem with wget. But I don't really understand that stuff.
This is the code I've been using unsuccessfully.
wget -r -l1 -H -t1 -nd -N -np -A.zip -erobots=off http://www.fec.gov/finance/disclosure/ftpdet.shtml#a2015_2016
Thanks for any help you can provide!
The zip links aren't present on the source code, that's why you cannot download them via wget, they're generated via javascript. The file list is "located" inside http://fec.gov//finance/disclosure/tables/foia_files_summary.xml under node <fec_file status="Archive"></fec_file>
You can code a script to parse the xml file and convert the nodes to the actual links because they've a pattern.
UPDATE:
As #cyrus mentioned, the files are also on ftp.fec.gov/FEC/, you can use wget -m for mirroring the ftp and -A zip to restrict the download to zip files, i.e.:
wget -A zip -m --user=anonymous --password=test#test.com ftp://ftp.fec.gov/FEC/
Or wget -r
wget -A zip --ftp-user=anonymous --ftp-password=test#test.com -r ftp://ftp.fec.gov/FEC/*
I am trying to download a tarball from GitHub using cURL, but it does not seem to be redirecting:
$ curl --insecure https://github.com/pinard/Pymacs/tarball/v0.24-beta2
<html><body>You are being redirected.</body></html>
Note: wget works for me:
$ wget --no-check-certificate https://github.com/pinard/Pymacs/tarball/v0.24-beta2
However I want to use cURL because ultimately I want to untar it inline with something like:
$ curl --insecure https://github.com/pinard/Pymacs/tarball/v0.24-beta2 | tar zx
I found that the URL after redirecting turned out to be https://download.github.com/pinard-Pymacs-v0.24-beta1-0-gcebc80b.tar.gz, but I would like cURL to be smart enough to figure this out.
Use the -L option to follow redirects:
curl -L https://github.com/pinard/Pymacs/tarball/v0.24-beta2 | tar zx
The modernized way of doing this is:
curl -sL https://github.com/user-or-org/repo/archive/sha1-or-ref.tar.gz | tar xz
Replace user-or-org, repo, and sha1-or-ref accordingly.
If you want a zip file instead of a tarball, specify .zip instead of .tar.gz suffix.
You can also retrieve the archive of a private repo, by specifying -u token:x-oauth-basic option to curl. Replace token with a personal access token.
You can also use wget to »untar it inline«. Simply specify stdout as the output file (-O -):
wget --no-check-certificate https://github.com/pinard/Pymacs/tarball/v0.24-beta2 -O - | tar xz
All the other solutions require specifying a release/version number which obviously breaks automation.
This solution- currently tested and known to work with Github API v3- however can be used programmatically to grab the LATEST release without specifying any tag or release number and un-TARs the binary to an arbitrary name you specify in switch --one-top-level="pi-ap". Just swap-out user f1linux and repo pi-ap in below example with your own details and Bob's your uncle:
curl -L https://api.github.com/repos/f1linux/pi-ap/tarball | tar xzvf - --one-top-level="pi-ap" --strip-components 1
with a specific dir:
cd your_dir && curl -L https://download.calibre-ebook.com/3.19.0/calibre-3.19.0-x86_64.txz | tar zx
