Несколько лет назад была сногсшибательная новость для фанатов Бэша:

ctypes.sh is a bash plugin that provides a foreign function interface directly in your shell. In other words, it allows you to call routines in shared libraries from within bash.

A (very) simple example will help illustrate:

$ dlcall puts "hello, world"
hello, world

# A more complex example, use libm to calculate sin(PI/2)
$ dlopen libm.so.6
0x172ebf0
$ dlcall -r double sin double:1.57079632679489661923
double:1.000000

ctypes.sh can extend bash scripts to accomplish tasks that were previously impossible, or would require external helpers to be written.

ctypes.sh makes it possible to use GTK+ natively in your shell scripts, or write a high-performance http daemon.
