File Comparison Utilities Under ZCPR2 CRC Check Utility Under ZCPR2 Examples :File Comparison Utilities Under ZCPR2 Twď utilitieó arĺ provideä witč ZCPR˛ tď comparĺ files® Ť Both utilities are simple in form to use. These utilities are: COMPARE -- Compares two files by reading one, computing its CRC value, saving its CRC and size, and then reading the other and seeing if they match DIFF -- Prints out a difference listing between two files; different bytes encountered at the same relative displacements from the beginning of thĺ fileó arĺ printeä iî hexadecimal¬ decimal, and ASCII forms These commands are invoked by the following forms: COMPARE or COMPARE // <-- Print Help COMPARE dir:file1.typ,dir:file2.typ M <-- Compare DIFF or DIFF // <-- Print Help DIFF dir:file1.typ,dir:file2.typ M <-- Compare Thĺ filĺ specó musô bĺ unambiguouó oň aî erroň wilě result® Ť Thĺ DIRş prefiř ió optional¬ anä maů bĺ á nameä directorů oň á Ť DU: form.
