How can I tell if my filesystem is mounted?
you can then add a check if the directory ‘some_dir’ is same as ‘your_dir’, and filesystem is same as yours. Check /proc/mounts. If you grep on the filesystem name and the path you want it mounted (maybe even a specific line with all options included) you can tell if the filesystem is mounted.
How to check the format of a filesystem?
If you need the filesystem type, use the -T switch, like so: To extract the filesystem type, you can parse it (use the -P switch to avoid df breaking lines if the device part is too long): So you can use that value in an if construct like so: Beware that the device column can contain spaces (but it’s rare), in which case the parsing will fail.
How to determine the filesystem of an unmounted device?
Another command that can come handy is # file -sL /dev/sdXY. This has one downside in that it does not work with the full block device. Requires the exact device to be passed. The output is quite neat though: All of these will always be output to stdout.
How to show the file system type in Linux?
Another way is to use the mount command. Without parameters it lists the currently mounted devices, including their file systems. In case you need to find out only one certain file system, is easier to use the stat command’s -f option instead of parsing out one value from the above mentioned commands’ output.
How to check if directory is mounted with grep?
Running the mount command without arguments will tell you the current mounts. From a shell script, you can check for the mount point with grep and an if-statement: if mount | grep /mnt/md0 > /dev/null; then echo “yay” else echo “nay” fi In my example, the if-statement is checking the exit code of grep, which indicates if there was a match.
How to check for read only filesystem in Linux?
If you want to check for a read-only block device (instead of a mounted filesystem) you can use. $ cat /sys/block/ /ro. which returns 1 if the filesystem is read-only or 0 if read-write. Note that above refers to the real device node.
