FONTCONVERT

A bash shell script for batch conversion of font files using fontforge. Supports both TrueType Font (TTF) and OpenType Font (OTF). Convert from either format.

.ttf files will be converted to .otf
.otf files will be converted to .ttf

By default new converted file names will be changed to lowercase and cleaned up to include only alpha-numeric characters. If you don't want the filename changed set config[cleanName]=false in the config array.

Any font files which cannot be converted due to being invalid, bad or corrupt files will be moved to the configured config[badDir] directory which by default is ./bad.

To enable a recursive search of the source directory increase the config[maxDepth] from 1.

Usage

FONTCONVERT (for use with fontforge)

Usage:

    Run script using: ./fontconvert.sh or bash fontconvert.sh

    Source files to be converted need to be in [.../fontconvert/src].

    .ttf files will be converted to .otf
    .otf files will be converted to .ttf

    New files will be saved in [.../fontconvert/dst].

    Bad or corrupt source files will be moved to [.../fontconvert/bad].

Script Setup

1. Clone the repo

cd ~
git clone https://github.com/bradsec/fontconvert.git
cd fontconvert

2. Make script executable

chmod +x fontconvert.sh

3. Copy fonts to be converted into the /fontconvert/src directory.

4. Run the script

./fontconvert.sh

The files will be converted and saved in the /fontconvert/dst directory.

Requirements

The fontforge package must be installed. Visit https://fontforge.org or https://github.com/fontforge/fontforge for more information.

• Debian/Ubuntu Linux install

sudo apt install fontforge

• macOS install (using homebrew)

brew install fontforge

• macOS may also require bash to be upgraded if running < bash v4

brew install bash
exec bash

Troubleshooting

Corrupt or bad font files will be prefixed by [FAIL]. The script will continue to process any remaining files. To view the full error of a failed file try running fontforge manually on the problem font file with the command below. Change the last two names fontin.ttf and fontout.otf to the applicable file name.

fontforge -lang=ff -c 'Open($1); Generate($2); Close();' fontin.ttf fontout.otf
