After days of going through pages of doco, running tests on terabytes of files, I finally made it all work.
log2timeline.py myhost.plaso sourceimage.vmdk
#myhost.plaso is going to be the output body file for psort. This creates the metadata and index. sourceimage.vmdk is the forensic hard disk we are analysing.
ls -lah
#checking to see if it’s created
psort.py -w myhost.csv myhost.plaso
