+
+* Getting files from internet
+
+There are multiple options to do that. First, create a temporary directory to
+train, make mistakes and learn.
+
+ * Use 'mkdir' in bash to do that
+
+#+begin_example sh
+  mkdir scratch
+#+end_example
+
+** You can use 'wget' to download files.
+
+Let's suppose that you want to download a pdf file from this website. Use ~wget~
+and include the link as arument in the terminal:
+
+#+begin_example sh
+  wget https://www.locus.ufv.br/bitstream/123456789/10320/1/texto%20completo.pdf
+#+end_example
+
+You can download multiple files. First, you should include the ~url~ of each file
+in a plain text file. Then use ~wget~ with the ~-i~ argument:
+
+#+begin_example sh
+  echo https://zenodo.org/record/275433/files/SS2SmallScaleDairyExport20150605.xml?download=1 > FilesToDownload.txt
+  echo https://zenodo.org/record/3962046/files/mountain_pastured_cows.csv?download=1 >> FilesToDownload.txt
+#+end_example
+
+
+#+begin_example sh
+  wget -i FilesToDownload.txt
+#+end_example
+
+** You can also use 'pandoc'
+
+Use the '-o' argument to rename the file if you want:
+
+#+begin_example sh
+pandoc https://itsfoss.com/download-files-from-linux-terminal/ -o tutorial.org
+#+end_example
+
+*** If you are a "GNU-emacs" person, then use 'eww' to browse the web
+
+So you can find the websites, copy the url and downloand files
+
+Within emacs use
+
+: M-x eww
+
+Then browse the web.
+
+Within the website you can use
+
+: M-x eww-copy-page-url
+
+** There is anothe great tool to download files: 'curl'
+
+Try this also and learn a litte about it.
+
+** Use R
+
+R has many options to get data from multiple sources.
+
+Check, for example, the function 'fread' from 'data.table' package
+
+
