Convert Website to PDF (recursively)

Question

Is there any way to convert a web page and its sub pages into one PDF file?

Answer 1

Save a list of Web pages as PDF file

• First install wkhtmltopdf conversion tool (this tool requires desktop environment; source):

  sudo apt install wkhtmltopdf 
  

• Then create a file that contains a list of URLs of multiple target web pages (each on new line). Let's call this file url-list.txt and let's place it in ~/Downloads/PDF/. For example its content could be:

  https://askubuntu.com/users/721082/tarek
  https://askubuntu.com/users/566421/pa4080
  

• And then run the next command, that will generate a PDF file for each site URL, located into the directory where the command is executed:

  while read i; do wkhtmltopdf "$i" "$(echo "$i" | sed -e 's/https\?:\/\///' -e 's/\//-/g' ).pdf"; done < ~/Downloads/PDF/url-list.txt
  

  The result of this command - executed within the directory ~/Downloads/PDF/ - is:

  ~/Downloads/PDF/$ ls -1 *.pdf
  askubuntu.com-users-566421-pa4080.pdf
  askubuntu.com-users-721082-tarek.pdf
  

• Merge the output files by the next command, executed in the above directory (source):

  gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -dPDFSETTINGS=/prepress -sOutputFile=merged-output.pdf $(ls -1 *.pdf)
  

  The result is:

  ~/Downloads/PDF/$ ls -1 *.pdf
  askubuntu.com-users-566421-pa4080.pdf
  askubuntu.com-users-721082-tarek.pdf
  merged-output.pdf
  

Save an entire Website as PDF file

• First we must create a file (url-list.txt) that contains URL map of the site. Run these commands (source):

  TARGET_SITE="https://www.yahoo.com/"
  wget --spider --force-html -r -l2 "$TARGET_SITE" 2>&1 | grep '^--' | awk '{ print $3 }' | grep -v '\.\(css\|js\|png\|gif\|jpg\)$' > url-list.txt
  

• Then we need go through the steps from the above section.

Create a script that will Save an entire Website as PDF file (recursively)

• To automate the process we can bring all together in a script file.

• Create an executable file, called site-to-pdf.sh:

  mkdir -p ~/Downloads/PDF/
  touch ~/Downloads/PDF/site-to-pdf.sh
  chmod +x ~/Downloads/PDF/site-to-pdf.sh
  nano ~/Downloads/PDF/site-to-pdf.sh
  

• The script content is:

  #!/bin/sh
  TARGET_SITE="$1"
  wget --spider --force-html -r -l2 "$TARGET_SITE" 2>&1 | grep '^--' | awk '{ print $3 }' | grep -v '\.\(css\|js\|png\|gif\|jpg\|txt\)$' > url-list.txt
  while read i; do wkhtmltopdf "$i" "$(echo "$i" | sed -e 's/https\?:\/\///' -e 's/\//-/g' ).pdf"; done < url-list.txt
  gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -dPDFSETTINGS=/prepress -sOutputFile=merged-output.pdf $(ls -1 *.pdf)
  

  Copy the above content and in nano use: Shift+Insert for paste; Ctrl+O and Enter for save; Ctrl+X for exit.

The answer to the original question:

Convert multiple PHP files to one PDF (recursively)

• First install the package enscript, which is a 'regular file to pdf' conversion tool:

  sudo apt update && sudo apt install enscript
  

• Then run the next command, that will generate file called output.pdf, located into directory where the command is executed, which will contains the content of all php files within /path/to/folder/ and its sub-directories:

  find /path/to/folder/ -type f -name '*.php' -exec printf "\n\n{}\n\n" \; -exec cat "{}" \; | enscript -o - | ps2pdf - output.pdf
  

• Example, from my system, that generated this file:

  find /var/www/wordpress/ -type f -name '*.php' -exec printf "\n\n{}\n\n" \; -exec cat "{}" \; | enscript -o - | ps2pdf - output.pdf
