Description: Change syntax of functions definitions to be POSIX compatible
 Running this shell script with the shell's -n option set fails, which means
 that the script has syntax errors. The erros are in the functions
 definitions which uses the bash syntax, but the script's interpreter is
 /bin/sh, which in Debian points to dash, which is a POSIX shell, so the
 definitions had to be adapted to the POSIX syntax.
