Workflow to eject disk image and trash DMG after software install?

[mlondon]

Wondering if anyone has developed a workflow that can eject a mounted disk image and trash the related DMG after installing software?

Thank you...

Not a workflow, but I did write a Service for that (so you can right-click on the disk image in Finder and do it that way).

 

Here's the Python script. Put this in a Run Script action with Language = /usr/bin/python input as argv:

import sys
import plistlib
from subprocess import Popen, PIPE

path = sys.argv[1]
dmg_path = None
info = Popen(["hdiutil", "info", "-plist"], stdout=PIPE).communicate()[0]
pl = plistlib.readPlistFromString(info)
for image in pl["images"]:
    for ent in image["system-entities"]:
        if ent.get("mount-point") == path:
            dmg_path = image["image-path"]
            break

if dmg_path:
    Popen(["hdiutil", "detach", path])
    Popen(["osascript", "-e", 'tell application "Finder" to delete POSIX file "%s"' % dmg_path])

You'll need to write your own Script Filter to find and list the mounted disk images, and pass the mount point (i.e. /Volumes/NAME) to the script.

Hi Deanise,

Very kind of you.

However I have no idea how to "write your own Script Filter to find and list the mounted disk images" !!!

[deanishe]

Fair enough. This should do the job.

 

I wonder if it's worth releasing properly…

I just came across this. Should come in very handy, thank you!

Thank you deanishe !!!

 

Works perfectly. Yes, why don't you release to the community? 

Happy to donate a little for your time.

Also, as some installers use ZIP instead of DMG, perhaps a way to either accommodate for both DMG & ZIP or a separate workflow for ZIP.

For ZIP files, you could use a standard Alfred File Filter configured to search ~/Downloads for ZIP files and connect that to a Run Script action that deletes/trashes the file.

Hi @deanishe,

 

I'm highly interested in this workflow as well, but the link is broken. A working one would be very appreciated. Thank you!

Here you go.

 

Thanks for spotting that. I've updated all the links on the page.

Thanks @deanishe just what I needed!

[kodiak]

Thanks @deniashe, it works beautifully.

Is there any way to "inject" this workflow into the normal eject feature?

That means appending the keyword "eject" to this workflow as well, and when a user has both DMGs and volumes mounted, "eject" will list them all, and the subtext for DMGs will also include "... and delete".

The only thing you can do is set the workflow and the "eject" feature to use the same keyword. They'll all show up at the same time, but the disk images will be duplicated, and it probably won't work very well.

 

To get a satisfactory experience, Andrew would have to add the "…and trash" feature to Alfred or someone would have to add eject features to this one.

This is very handy. I don't know anything about scripting, but I'm wondering if it would be a simple thing to create a version of that script that does the following:

 

Ejects all disk images (not disks). 

 

That's it. No selecting, no trashing, just a one-button disk image ejector. 

 

Failing that, I presume that deleting the second half of your script will do the ejecting part without the trashing part, as so:

 

log() {
    echo "$@" >/dev/stderr
}

log "name=$dmgname, mount=$dmgmount, path=$dmgpath"

# unmount
out="$( hdiutil detach "$dmgmount" 2>&1 )"
hds=$?
if [[ $hds -ne 0 ]]; then
    log "hdiutil exit status: $hds"
    log "$out"
    echo "$out"
    exit 1
fi

@deanishe This one was easily converted to Python 3. Since there’s no public repo to submit a PR, added to my list of requested Workflows (direct download).

Hi @vitor, the above link seems broken. Do you think you could give another one? Thanks!

@odapg Fixed!
