check -- Command Check file system check [-s] filesystem ... check uses the commands icheck and dcheck to check the consistency 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 automatically. 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). See Also clri, commands, icheck, ncheck, sync, umount 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 This command has largely been superceded by fsck.
