If you are using a recent shell, you can try process substitution:
Code:
$ comm -23 <(sort file1) <(sort file2) > file4
$ comm -23 file4 <(sort file3) | awk .... > file5

For further refinement, I'd need some input and desired output data.

NAME
deleg_proc - Creation of comm delegates (procedures) SYNOPSIS
package require Tcl 8.3 package require interp::delegate::proc ?0.2? ::interp::delegate::proc ?-async? name arguments comm id _________________________________________________________________ DESCRIPTION
This package provides a single command for the convenient creation of procedures which delegate the actual work to a remote location via a "channel" created by the package comm. API
::interp::delegate::proc ?-async? name arguments comm id This commands creates a procedure which is named by name and returns its fully-qualified name. All invokations of this procedure will delegate the actual work to the remote location identified by the comm channel comm and the endpoint id. The name of the remote procedure invoked by the delegator is [namespace tail name]. I.e., namespace information is stripped from the call. Normally the generated procedure marshalls the arguments, and returns the result from the remote procedure as its own result. If however the option -async was specified then the generated procedure will not wait for a result and return immediately.
