Case sensitive — Linux is, and grading LS as ls would teach a falsehood.
Why
free reads /proc/meminfo and summarises memory and swap. -h (--human) scales each figure to a readable unit instead of the default kibibytes. Related options are -m and -g for fixed megabyte or gigabyte units, and -s for repeating the report at an interval.
Where this comes from
- Cited
- LPI exam objective 103.5
- What it says
- Report memory usage with free.
