Unfortunately, there is no library available in Clean for executing 
system commands. You can use ccalls (see the file 
Help\CallingCFromClean.html in your Clean distribution for instructions) 
to call a self-defined C function which executes a system command for you.

There is no library available for matching a String value to a regular 
expression. You can of course use an appropriate C library in 
combination with ccalls.

No problem, you are free to ask any questions about Clean.
