Convert Website to PDF (recursively)

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

Solution 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.

Usage:

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
