bash - Scroll a shell script output without piping it into less -


i have bash script.sh. can scroll output this:

$ ./script.sh | less

but how make output display scrollable automatically, without having pipe through less? in other words, how put functionality right script itself? want execute script this:

$ ./script.sh

i know might able write different script execute first 1 , pipe output automatically don't want have write script first 1 want do. know mean?

you can write script this:

#!/bin/bash (      script here  ) | less exit $pipestatus

this pipe script output through less if output terminal (so can ./script.sh > file without paging), , preserves script's exit code.
