check Command check
Check file system
check [-s] filesystem ...
check uses the commands icheck and dcheck to check the consis-
tency of a file system. It acts on each argument filesystem in
turn; it calls first icheck and then dcheck on each to detect
problems.
If -s is specified, check attempts to repair any errors automati-
cally. You should first unmount the file system, if possible.
If the root device is involved, you should be in single-user mode
and then reboot the system immediately (without typing sync).

***** Notes *****
Certain errors, such as duplicated blocks, cannot be fixed
automatically. Decisions must be made by a human.
In earlier releases of COHERENT, check acted upon a default file
system if none was specified.
This command has largely been superceded by fsck.
