== Using the ebook-convert tool from Calibre ==

To convert an EPUB file to MOBI format on Ubuntu, you can use the '''ebook-convert''' tool from '''Calibre'''. Here’s how you can do it:

* Install Calibre
If you haven’t already, you can install Calibre using the following command:

<code>sudo apt-get install calibre</code>

=== Convert EPUB to MOBI ===

Use the ebook-convert command to convert your EPUB file to MOBI. <br>
For example, to convert a file named book.epub to book.mobi, you would use:
<br><code>ebook-convert book.epub book.mobi</code>

==== Other file formats are also supported with ebook-convert ====
<code>ebook-convert "book.azw3" "book.mobi"</code>

=== Convert in bulk ===

* This assumes you have a '''Directory''' with books.epub you want converted to books.mobi in bulk.
* This script should be saved and run in said directory.

<code>$EDITOR convert_epub_to_mobi.sh</code>

<pre>
#!/bin/bash

# Check if ebook-convert is installed
if ! command -v ebook-convert &> /dev/null
then
echo "ebook-convert could not be found. Please install calibre."
exit 1
fi

# Loop through all .epub files in the current directory
for file in *.epub; do
# Check if the file exists (to avoid processing '.*.epub' which would be all files)
if [ -f "$file" ]; then
# Get the filename without the extension
filename="${file%.epub}"
# Convert the file
ebook-convert "$file" "${filename}.mobi"
echo "Converted $file to ${filename}.mobi"
fi
done
</pre>

Now you can run with bash or make excultable

* With bash
<code>bash convert_epub_to_mobi.sh</code>

* Make excultable
<code>chmod +x convert_epub_to_mobi.sh</code>

<code>./convert_epub_to_mobi.sh</code>

==== system wide script ====

If you are gonna be using a lot, can make script which you install in /usr/bin/ so you can just use:<code>convert_epub_to_mobi /path/to/epub/files /path/to/output/mobi</code>

<code>$EDITOR convert_epub_to_mobi</code>

<pre>
#!/bin/bash

# Check if ebook-convert is installed
if ! command -v ebook-convert &> /dev/null
then
echo "ebook-convert could not be found. Please install calibre."
exit 1
fi

# Check if correct number of arguments are provided
if [ "$#" -ne 2 ]; then
echo "Usage: $0 <source_directory> <output_directory>"
exit 1
fi

SOURCE_DIR="$1"
OUTPUT_DIR="$2"

# Check if source directory exists
if [ ! -d "$SOURCE_DIR" ]; then
echo "Source directory does not exist: $SOURCE_DIR"
exit 1
fi

# Create output directory if it doesn't exist
mkdir -p "$OUTPUT_DIR"

# Loop through all .epub files in the source directory
for file in "$SOURCE_DIR"/*.epub; do
# Check if the file exists (to avoid processing '*.epub' if no files match)
if [ -f "$file" ]; then
# Get the filename without the path and extension
filename=$(basename "$file" .epub)
# Convert the file, placing the output in the specified directory
ebook-convert "$file" "$OUTPUT_DIR/${filename}.mobi"
echo "Converted $file to ${filename}.mobi in $OUTPUT_DIR"
fi
done
</pre>

Make it Executable and Move to /usr/bin/:

<code>sudo cp convert_epub_to_mobi /usr/bin/</code>

<code>sudo chmod +x /usr/bin/convert_epub_to_mobi</code>

Now you can run the script from anywhere by specifying source and output directories:

<code>convert_epub_to_mobi /path/to/epub/files /path/to/output/mobi</code>

* Example: will convert all epubs in Downloads to newly created Kindlebooks directory
<code>convert_epub_to_mobi Downloads/ Kindlebooks</code>

Notes:
* This script will create the output directory if it does not exist.
* It checks for the existence of the source directory before proceeding.
* The usage message helps remind users of the correct command structure if they forget.
* As before, ensure ebook-convert (part of Calibre) is installed on the system.
* Error handling for ebook-convert isn't included; you might want to add that for production use or for better user feedback on conversion failures.
