Suppose do you want test if /mnt/disk is a mount point in a shell script. How do you do this?
Using the mount Command One way we can determine if a directory is mounted is by running the mount command and filtering the output. The above line will exit with 0 (success) if /mnt/backup is a mount point. Otherwise, it'll return -1 (error).
See mount points using the mount command:If followed by the -l flag, it will also show the mount point name; the output is similar to the mount command without flags.
In Disk Manager, right-click the partition or volume that has the folder in which you want to mount the drive. Click Change Drive Letter and Paths and then click Add. Click Mount in the following empty NTFS folder. Type the path to an empty folder on an NTFS volume, or click Browse to locate it.
Mount Path. The path to which the data is written to and read from. Free Space. Not available for cloud storage. Size on Disk.
Not relying on mount
, /etc/mtab
, /proc/mounts
, etc.:
if [ `stat -c%d "$dir"` != `stat -c%d "$dir/.."` ]; then echo "$dir is mounted" else echo "$dir is not mounted" fi
When $dir
is a mount point, it has a different device number than its parent directory.
The benefit over the alternatives listed so far is that you don't have to parse anything, and it does the right thing if dir=/some//path/../with///extra/components
.
The downside is that it doesn't mark /
as a mountpoint. Well, that's easy enough to special-case, but still.
I discover that on my Fedora 7 there is a mountpoint command.
From man mountpoint:
NAME mountpoint - see if a directory is a mountpoint SYNOPSIS /bin/mountpoint [-q] [-d] /path/to/directory /bin/mountpoint -x /dev/device
Apparently it come with the sysvinit package, I don't know if this command is available on other systems.
[root@myhost~]# rpm -qf $(which mountpoint) sysvinit-2.86-17
