## FSTRIM BASICS
|
|
|
|
fstrim should be run regularly to clean up disk space.
|
|
You can think of it as a more modern form of disk defragmentation.
|
|
It potentially can extend the life of an ssd hard drive.
|
|
|
|
fstrim should be run once a week, but should also not be more often.
|
|
The most basic essential command to run fstrim is:
|
|
|
|
```bash
|
|
sudo fstrim -a -v -m 1MB
|
|
```
|
|
|
|
Be conscientious when running fstrim like this, as the -a flag indicates we wish
|
|
to run fstrim on all mounted file systems that accept this command. The -m 1MB
|
|
indicates we wish to only trim in minimum of 1 megabyte chunks. The -v flag
|
|
indicates we wish to see 'verbose' output (like many UNIX/UNIX-like commands).
