From here, build a new /etc/fstab from scratch, it's pretty basic...
Main things to note...
1) /etc/mtab check it for proc etc.
2) Is my fs ext3 or ext4 or ??? check /etc/mtab.
3) Swap? well the fdisk will tell you if you had it...
4) Any other mounts that I care about, eg. /var etc.
I'm on a Solaris box that doesn't have -o as an option for grep (trying to return match only).
Is there any way to get this functionality without the -o option?
I've tried both sed and awk doing something like:
echo "this is a test" | awk '/test/'
or
echo "this is a test | sed '/test/p'... (8 Replies)

swapoff
SWAPON(8) Linux Programmer's Manual SWAPON(8)NAME
swapon, swapoff - enable/disable devices and files for paging and swapping
SYNOPSIS
/sbin/swapon [-h -V]
/sbin/swapon -a [-v] [-e]
/sbin/swapon [-v] [-p priority] specialfile ...
/sbin/swapon [-s]
/sbin/swapoff [-h -V]
/sbin/swapoff -a
/sbin/swapoff specialfile ...
DESCRIPTION
Swapon is used to specify devices on which paging and swapping are to take place. Calls to swapon normally occur in the system multi-user
initialization file /etc/rc making all swap devices available, so that the paging and swapping activity is interleaved across several
devices and files.
Normally, the first form is used:
-h Provide help
-V Display version
-s Display swap usage summary by device. Equivalent to "cat /proc/swaps". Not available before Linux 2.1.25.
-a All devices marked as ``swap'' swap devices in /etc/fstab are made available. Devices that are already running as swap are silently
skipped.
-e When -a is used with swapon, -e makes swapon silently skip devices that do not exist.
-p priority
Specify priority for swapon. This option is only available if swapon was compiled under and is used under a 1.3.2 or later kernel.
priority is a value between 0 and 32767. See swapon(2) for a full description of swap priorities. Add pri=value to the option field
of /etc/fstab for use with swapon -a.
Swapoff disables swapping on the specified devices and files. When the -a flag is given, swapping is disabled on all known swap devices
and files (as found in /proc/swaps or /etc/fstab).
NOTE
You should not use swapon on a file with holes. Swap over NFS may not work.
