how drop first column in output using sed code example

Example: delete first column bash

Just use cut command with a defined delimeter as a space ' ' and choose
to cut since second word match until end '-f2-' as for example:
cat file.txt | cut -d ' ' -f2-
If for example space delimiter ' ' is repeated in your line check how
many times, since matching word number must then be adapted. For example:
history | cut -d ' ' -f4-
