What are the elements of constructs like the one you presented?

• variable interpolation or expansion
• quoting and escaping
• streams
• pipes

All these elements you find in perl also. Aliases may be setup with subroutines.

That said, you could

• construct a generic way to process pipe read and writes, streaming, variable interpolation and escaping in perl
• write functions that do alias expansion and construct a command lines suitable to be passed to a shell via open or system
• or stuff those existing constructs into shell scripts, which can then be invoked from perl.

It all depends on lazieness, hubris, and impatience... I'd write shell scripts.
