What happened

On Debian systems, the default /bin/sh is linked to dash. Our current script install-plugin.sh uses a substring extraction syntax ${line:0:1} that is tailored to bash. Consequently, this causes the script to error out with "Bad substitution" when executed under dash on Debian. The script needs modification to ensure compatibility across sh (particularly dash), bash, and zsh.
