fsck -t option

hi

I am new to Linux. I am writing a bash script to do a filesystem check in all the filesystems except vfat, dos and root specified in /etc/fstab. From the man page I found that the -t option will help me to solve this problem.

but I am not sure of the syntax of the command.

can someone please gimme an example syntax.

currently in the bash I used the following syntax and it throwed me an error

#fsck -ARs -t !dos,!vfat

Thanks for ur time.

Maybe I'm completely off, but I'd think that you can't
negate what wouldn't be checked in the first place?

As far as I know fsck has no means to check these
two in the first place.

Try this

Code:

fsck -ANt nodos,novfat

A - Check all listed in fstab
R - Omit / filesystem if it's already mounted
t nodos,novfat - Do not check dos and vfat type fs

Running fsck on mounted fs is not recommended since it can cause fs damage. So you would prefer to do a read-only fsck on such. (Check -n option)

-s option (in your entry) tells to serialize the checks (this is not recommended if you intend to use fsck non-interactively)

Uh, someone should explain that there is no need to write a script to run fsck at all............In most distros, fsck run automagically after a filesystem has been mounted 20 times (slackware is one )..........fsck will also run automatically IF a filesystem was un-mounted improperly.....(like after a hard re-boot ).........you can change the setting so fsck runs after 5 or 10 mountings, but there is no need really to mess with it............

Yes, quite right. Most distros have sheduled fscks and in unexpected system halts. But there may be requirements, where you need to do manual fsck.

Anyway Linuxuser_81 didn't say what was his/her requirement. So I assumed that he knows what he is doing, and gave him some tip.
