[SOLVED] Zenity w/ IF statement to check if selected directory is not EXT3

[mdpalow]

Hi everyone,

I need some help with checking whether or not a directory is EXT3 or not.

#!/bin/bash

zenity --directory --file-selection

This brings up Zenity where I can click on a drive.

I would like the output (drive/location selected) to be checked to see if it's a file system that is compatible with accepting permissions (EXT3, etc...) If it's not compatible (ex: FAT32 or NTFS) then I want to loop back.

I can't find anything that I can use to put in an IF/WHILE statement for checking file system type, so I can loop if it's FAT32 or NTFS.

Does anyone know how to do this?

thanks.

P.S. One last thought. Is it possible to make the above Zenity code open in a specific folder and not allow me to change it?

thanks again...

Something like this perhaps?

dir=$(zenity --file-selection --directory)

while [ $(stat --file-system -c "%T" "$dir") != ext2/ext3 ]; do
  zenity --error --text="Directory must be in an ext2 or ext3 filesystem"
  dir=$(zenity --file-selection --directory)
done

echo "Ok, $dir is fine"

And I don't think you can force a directory in zenity like that. I guess the closest thing would be to make the list of legal files and put it in a "zenity --list"

EDIT: Oh, mdpallow, hello again

lol

thank you geirha!

Sorry to take so long to reply, but I was away for a while and then needed to have someone test it for me to see if they got the same problem I did.

Basically, the script works perfectly against my usb flash drive, but when I tested it against my usb hard drive that is ntfs partitioned, I get:

[: too many arguments

in the " while [ $(stat --file-system -c "%T" "$dir") != ext2/ext3 ]; do "

When selecting the NTFS partition (USB Hard Drive), It says it's ok and moves forward. I would think it shouldn't do that.

Can you think of anything? A friend is getting the same error.

Thanks...

do you think it allowed because of ntfs-3g , which allows writing to NTFS?

[mdpalow]

seems to be another small problem.

Once you enter the loop (after selecting a fat file system) and then click CANCEL, you get:

stat: cannot read file system information for `': No such file or directory
/home/me/Desktop/new file: line 13: [: !=: unary operator expected
Ok, is fine

line 13 is the WHILE line...

Is there anyone else on-line who might be able to help??

The NTFS one probably has spaces in it, so we'll need to enclose that stat command in quotes. And checking if zenity failed is of course a good idea too, so:

dir=$(zenity --file-selection --directory)
if [ $? != 0 ]; then
  echo "ok, bye bye"
  exit 1
fi

while [ "$(stat --file-system -c "%T" "$dir")" != "ext2/ext3" ]; do
  zenity --error --text="Directory must be in an ext2 or ext3 filesystem"
  dir=$(zenity --file-selection --directory)
  if [ $? != 0 ]; then
    echo "ok, bye bye"
    exit 1
  fi
done

echo "Ok, $dir is fine"

Thank you very much Geirha

That worked.
