nop

Command nop

The nop command allows you to easily skip instructions.

gef ➤  help nop
Patch the instruction(s) pointed by parameters with NOP. Note: this command is architecture
aware.
Syntax: nop [LOCATION] [--nb NUM_BYTES]
  LOCATION      address/symbol to patch
    --nb NUM_BYTES      Instead of writing one instruction, patch the specified number of bytes

LOCATION indicates the address of the instruction to bypass. If not specified, it will use the current value of the program counter.

If --nb <bytes> is entered, gef will explicitly patch the specified number of bytes. Otherwise it will patch the whole instruction at the target location.
