Have you tried this?

`echo /Volumes/$user`

To give you:

<string>`echo /Volumes/$user`</string>

When you do defaults write com.apple.dock persistent-others -array-add, you are passing it a string so it will read $user as a string. You use tics to escape out of the string to execute a command which will be substituted in the string.

J.I.

Where, between the <string> and </string> tags? Just tried that and it gave me a dock item of $user`

Have you tried putting $user in quotes like below?

server=dscl . -read /Users/"$user" | grep SMBHome: | cut -d '' -f 3

Consequently, I've also tried using ```
jamf modifyDock -file /Volumes/$user
```
But it returns an error that I need to specify an ID. Seems like a bug in the modifyDock verb as the help for it seems to indicate that you can use either -file or -id, not that it requires both.

Have you tried putting $user in quotes like below?

server=dscl . -read /Users/"$user" | grep SMBHome: | cut -d '' -f 3

Didn't change anything. The issue seems to be how to escape the variable out so that Defaults isn't processing it literally.

Have you tried:

jamf modifyDock -file /Volumes/`echo $user`

J.I.

jamf gives me the

You must specify a an [sic] ID. Type "jamf help modifyDock" for more info

error.

or even ```
whoami
``` which will return a single string of the current username.

J.I.

Can you substitute $USER in place of your existing $user? $USER should give you the current logged-in user without needing to define it otherwise.

Good idea, but dock item of

`whoami`

There's got to be something about Defaults that processes everything literally. It's sort of obnoxious at this point. ha

Nothing in the man page about it. Wonder if I should try plistbuddy instead.

Defaults is taking a string passed to it via the shell, it doesn't see the variable at all.

J.I.

Can you substitute $USER in place of your existing $user? $USER should give you the current logged-in user without needing to define it otherwise.

Result: $USER dock item. It's almost comical at this point.

I'm going to go crowbar this in with plistbuddy. Maybe I'll have better luck.

Yeah, seems to me defaults can't use a variable in that kind of command for whatever reason. I guess its just a limitation of the program.

Try PlistBuddy as you state or look at 3rd party tools. You should be able to do this with existing tools though, so its pretty strange.

R0190381:~ jamieivanov$ defaults write com.apple.dock persistent-others -array-add "<dict><key>tile-data</key><dict><key>file-data</key><dict><key>_CFURLString</key><string>`echo /Users/$USER`</string><key>_CFURLStringType</key><integer>0</integer></dict><key>showas</key><integer>2</integer></dict><key>tile-type</key><string>directory-tile</string></dict>"

R0190381:~ jamieivanov$ killall -9 Dock

That placed an icon on the Dock to the appropriate path. It worked just fine for me. Like I said, defaults only reads a string and using ticks (the tilde key to the left of the "1" key), not single quotes.

J.I.

This also seems to work.

tmpStr='<dict><key>tile-data</key><dict><key>file-data</key><dict><key>_CFURLString</key><string>/Volumes/'$user'</string><key>_CFURLStringType</key><integer>0</integer></dict><key>showas</key><integer>2</integer></dict><key>tile-type</key><string>directory-tile</string></dict>'



defaults write com.apple.dock persistent-others -array-add $tmpStr

when you put things inside of a 'single quote' they don't expand
what i would suggest is trying to wrap that argument in " to see if that works, but i fear the <> will get interpreted at that point.
we do something very similar in perl like this:
system("defaults", "write", "$target", "persistent-apps", "-array-add", "<dict><key>tile-data</key><dict><key>file-data</key><dict><key>_CFURLString</key><string>$app_path</string><key>_CFURLStringType</key><integer>0</integer></dict></dict></dict>");

nice Bill, i was just going to test something like, that because it was gnawing at my brain how to set a tmp string in shell and pass it. i was worried that you would need single quotes in the command and then not get anything close to what you wanted to get.

Looks like Jamie is spot on. Enclose it in double quotes, not single and it seems to work. In fact, I didn't need to do the echo portion. Something like the below works as is:

defaults write com.apple.dock persistent-others -array-add "<dict><key>tile-data</key><dict><key>file-data</key><dict><key>_CFURLString</key><string>**/Users/$user/**</string><key>_CFURLStringType</key><integer>0</integer></dict><key>showas</key><integer>2</integer></dict><key>tile-type</key><string>directory-tile</string></dict>"

It adds my home folder to the Dock. I'm guessing the same would be true if doing /Volumes/$user/ instead.

Bill gets a cookie - or beverage of his choice should we run into eachother at the NUC.

Holy ba-jeebus I don't know why that was so hard.

For some reason the backticks (a.k.a grave) aren't working for my on this system (10.7.4). I get what they do but for some reason defaults for me was totally ignoring that.

It wasn't so hard. Also, I'm running 10.7.4 and using bash just like everyone else. The shells are the same unless there is a problem with encoding/localizations or a keyboard malfunction. It's mere shell scripting.

Though what was difficult was the harder-than-it-needs-to-be solutions.

J.I.

I think Bill is on the right path here. It is like trying to pass a bash variable in a bash script, apple script, or say into an awk program. The output doesn't carry over since they are separate sets of binaries.

So, you can echo out the results, like so:

echo "a bunch of xml settings" > com.apple.somepropertlylist

or

setttings="<xml stuff that makes you go cross eyed>"



defaults write com.someplist $settings

or

echo $settings > com.someplist

I haven't tested any of these methods but I have used very similar things using bash to apple script, apple script to bash, and bash to awk.

I will try to test some of these this weekend - only if time permits.

Thanks,
Tom

A little complicated much? Also, don't forget to add some newline strings to make it a little easier to read if you had to manually manipulate the plist. But don't over-engineer, that's when more problems get introduced. Keep it simple, efficient, and functional. There is no need to re-invent the wheel if it already exists.

J.I.

why don't you use mcx for this and skip all the fragile code?

doesn't this do about the same thing except for mounting?

com.apple.dock
MCXDockSpecialFolders-Raw

<array>

    <string>AddDockMCXOriginalNetworkHomeFolder</string>

</array>

there should be a key for com.apple.loginwindow that mounts the share automatically, too.

Because the same script the original poster made could be accomplished in 2 lines as well. Mounting and creating a Dock icon.
