cP a1 [a2 .. aN]       where a1 [a2 .. aN] are set variables

cP`mtm~ a1 [a2 .. aN]

cP/mtm~ a1 [a2 .. aN]

cP

When specified by itself then the operation is performed on the object on top of the stack and the one that is one below it, then the result is pushed on the stack

●  Operator cP gets the element-checksums partition

Use the operator cP to get the partition of datasets based on the element checksums. Use the cP operator to get the elements partition of one or many set variables. The partitions are based on the element checksums in each set variable.

 

cP EXAMPLE
The following example shows how to partition three directories based on their file checksums. To test with this operation, start ASPL by loading the sample workspace WS1 then we issue the cP operation.

 

cP OPERATION

# aspl WS1

①  aspl> cP a3 a4 a5
    (partition a3 a4 a5 based on their element (or filename) checksums)

②  aspl> cP`mtm= a3 a4 a5
    (partition a3 a4 a5 based on their element (or filename) checksums such that the mtimes are equal)

③  aspl> cP`mtm~ a3 a4 a5
    (partition a3 a4 a5 based on their element (or filename) checksums such that the mtimes are unequal)

 

● Tickable Predicates for cP

This cP is tickable with predicates that are shown in the following table:

       a yellow note
cP`_  gets the element-checksums partition 
cP`c=  gets the element-checksums partition such that they have the same checksum 
cP`c~  gets the element-checksums partition such that they have different checksums 
cP`c~~  gets the element-checksums partition such that they have all over different checksums 
cP`h=  gets the element-checksums partition such that they have the same entropy 
cP`h~  gets the element-checksums partition such that they have different entropies 
cP`h~~  gets the element-checksums partition such that they have all over different entropies 
cP`mtm=  gets the element-checksums partition such that they have the same make time 
cP`mtm~  gets the element-checksums partition such that they have different make times 
cP`mtm~~  gets the element-checksums partition such that they have all over different make times 
cP`ks=  gets the element-checksums partition such that they have the same ksum 
cP`ks~  gets the element-checksums partition such that they have different ksums 
cP`ks~~  gets the element-checksums partition such that they have all over different ksums
