CONTENTS

SYNOPSIS


boottrace utility [argument ...]

DESCRIPTION

The boottrace utility executes the specified utility, creating two boottrace(4) trace entries before and after its execution.

ENVIRONMENT

The PATH environment variable is used to locate the requested utility if the name contains no ‘/’ characters.

EXIT STATUS

If utility was executed successfully, its exit status is returned.

If utility was found but could not be executed, an exit status of 126 is returned. If utility could not be found, an exit status of 127 is returned.

I have a natural revulsion to any operating system that shows so little planning as to have to named all of its commands after digestive noises (awk, grep, fsck, nroff).
