[Automator] Using an ls command and then getting the finder items?

How about using 'mount'

mount | awk '

$0 ~ " on / " { next }

$0 ~ "hfs" {print $1}

'

This should give you a list of HFS formated partitions but exclude the boot disk. You should be able to pass this to diskutil umount

diskutil umount $(mount | awk ' $0 ~ " on / " {next} $0 ~ "hfs" { print $1 }' )

which should unmount all the HFS formated, but exclude the boot disk.

If you want other disk formats to be unmounted, then you could just add additiona $0 ~ "xyz" { print $1 } statements to the awk command script

Issue the 'mount' command from an Applications -> Utilities -> Terminal session, and see what it says the format of the different volumes you have mounted.

All that 'awk' is doing is using search strings on each line to decide to skip (next) or print the 1st field which is the device name.

Looking at the 'mount' output for yourself will tell you what you can search for.

You can do this with Applescript without looking for the external drives:

tell application "Finder" to eject every disk

(if you must have an Automator App, then just put this in the Run AppleScript Action)

You can also use find in Terminal:

find /dev -name "disk[1-9]" -exec diskutil eject {} \;

See: http://stackoverflow.com/questions/2049758/is-there-a-way-to-eject-all-external- hard-drives-from-the-command-line-os-x

Just do

tell application "Finder"

eject (every disk) - other syntaxes will work all disks, the disks, etc.

end

All disks but the root drive will be unmounted.

A simple one-liner will do this (and yes, it will only eject disks which are "ejectable"):

tell application "Finder" to eject every disk

Note that this Applescript will also eject disk images.

OP is looking to eject all external hard drives, the Applescript solution will also eject mounted disk images.

Where did he say that? He only stated that he wanted to avoid ejecting the HD, which isn't possible in any case.

If avoiding .dmg is the issue, one way would be to hard code the possible disk names by using a list like this:

(*

Replace the example volume names with your own volume names inside the curly brackets below;

Names must be quoted and comma separated as shown.

Spaces in names ARE allowed. You can name as many or as few volumes as you wish.

*)

set gDiskList to {"External1 500GB", "Time Machine HD", "External2 HD", "External3 45GB"}

repeat with i in gDiskList

set i to quoted form of i

try

do shell script "diskutil umount " & i

end try

endrepeat

Hmm, one could also get a list of only dmg mounts with

do shell script "hdiutil info"

You'd then need to do some sedding or grepping to sort out the names from 'image path'. That's more work than I'm willing to put into it right now, not being convinced as yet that this is at all what the OP is after.

1st sentance: "So i want to make an automator app that looks for all external hard drives and then ejects them."

Disk images fall in the no-man's land, being neither "internal", "external" nor indeed "hard" drives; they're just "mounted volumes". Nothing in the context of the OPs suggested these were a consideration. But in any case, I've already hinted at how one might go about doing that with hdiutil.

Until we hear from the OP, I don't see any further use in debating this point.

OP could not have been any more specific when stated " all external hard drives" -- Nothing to debate, you're just wrong 🙂 (now, he may not care that mounted disk images are ejected with your Applescript suggestion (that was already posted 2x, btw), but that's a different issue).

Hello

If it is safe to assume you're ejecting every device node mounted on mount point in /Volumes, you'd try this:

#!/bin/bash

for dev in $(mount | perl -lne 'print $1 if m%(^/dev/[^[:space:]]+) on /Volumes/.*%io')
do
    diskutil eject "$dev" >/dev/null 2>&1 &
done

* If you're unmounting and not ejecting it, issue diskutil unmount instead:

#!/bin/bash

for dev in $(mount | perl -lne 'print $1 if m%(^/dev/[^[:space:]]+) on /Volumes/.*%io')
do
    diskutil unmount "$dev" >/dev/null 2>&1 &
done

Purely as an intellectual exercise, I decided to write a script to see if I could distinguish dmgs from other devices in /Volumes.

The following script appears to work to unmount every "external" (sic "ejectable") device except DMGs, though my testing hasn't been robust enough to guarantee it (at least one problem would be if you had more than 99 mounted devices, it would fail).

It could also be used to do the reverse - unmount only DMGs and nothing else - by adding 'not' to the conditional in the 'compareAndEject' handler.

set diskList to the result

set origDeLims to AppleScript'stext item delimiters

set myDMGNames to {}

set x to {}

try

set x to (do shell script "hdiutil info | grep '/dev'") as text

end try

set AppleScript'stext item delimiters to origDeLims

if x is not equal to {} then

repeat with i from 1 to count of paragraphs in x

set z to getDMGName(paragraph i in x)

set end of myDMGNames to z

end repeat

compareAndEject(myDMGNames, diskList)

#add a # to the next line and remove the # from the following line if not on 10.9
