How can I get the path name and rename it?

I Hope someone who knows more about automator than I can help me out here. What I'm trying to do is get the path file name, while also changing part of it. Here is my example:
I can get the path name with this "Get Path" script I found http://automatorworld.com/archives/get-path/all-comments/
It does half the job so I just need to tweak it but know how. When I get the path this is what I'll get: /Volumes/Public/Creative Services/Campaigns/2010/NCDDiv-32CDV Upgrade/NCDDIV-32Versions.xls
I need to remove the beginning part"/volumes" to "file://///nhmanmkt01"
This is so I can send the path from our sever where we keep our files to my windows friends so they can open it.
Thanks for any help you can provide!

for f in "$@"
do
echo "$f"|sed 's%/Volumes%file://///nhmanmkt01%'
done</pre>
set the script to accept input as arguments
3. copy to clipboard
save it as a finder plugin.

Terminal how can i get the picture dimension of a file?

Is it possible to get the dimension of an picture (120 x 120 px) via terminal command? The information is visible under the finder "getinfo" command for picture files. Can anyone help?

You can get image pixel size info using the ImageMagick utilities, which is a GNU package available for installation via the fink pacakage manager, then you can use the terminal command:
identify image.gif
ImageMagick also has several other useful conversion and image processing utilities.
http://www.finkproject.org/
http://www.imagemagick.org/script/index.php
Good luck.
P.S. - There may be ways to interact with AppleScript from Terminal to get the Finder info from a file, but I don't know how to do that.

How can i get the column names in CSV file.

Hi,
After execution of infospoke i can not see the column names in that file.How can i get column of respective infoprovider?
Thanks,

Hello Gana,
Actually while exporting the data using Info Spoke, we have the possibility to modify the data that we send. This is possible using transformations.
In your Info Spoke, you have a tab called Transformations.
Here you need to create an implementation and then use BADi to populate data.
Check if you can write a start routine sort of thing here and insert a new record into the internal table by hardcoding with your field headings.
Let me know if you dont know how to create transformations.

How can we get the artset from a .ai file without opening it?

Hello All,
I have one .ai file, lets say sample.ai file. located in C drive. so the complete file path is "C:\Sample.ai".
and lets assume the sample.ai file has one traingle shape(3 path type arts) in it.
Now I want to get the 3 path arts (artset) from sample.ai file without opening it in AI.
The function protoype is like below
AIArtSet& artSet GetArtSetFromAFile( ai::FilePath& filePath );
Is there any API like above function in AI? or is it possible to get the art(s) from a file without opening it in AI?

Not to my knowlege. The API only operates on active documents as far as I know.

How can I get the exact pathname for a file on my computer?

I need to enter a command in Terminal that contains the pathname of an application. I know what the path is but Terminal does not recognize it. How do I make sure the pathname is in the correct form?

Enter the command up to the point of entering the file path and add a space, then drag the file into the terminal window. It will fill out the path.
If you need to go further into the contents of the Application package, you can continue with /Contents...
Another way is to start typing and then hit Tab to auto-complete. It will stop where it can't determine the next letter.
So, type /App tab and it will fill in /Applications. Type a / and start with the name of the app, then tab and it should complete. Continue till you have the correct path.
Spaces will be replaced with \<space>, so, App Store would end up as /Applications/App\ Store.app

How can I get the script Export Layers to Files to export compressed pngs?

            pngSaveOptions = new PNGSaveOptions();
            pngSaveOptions.interlaced = false;
            // trying to compress png files
            pngSaveOptions.compression = 9;
            docRef.saveAs(saveFile, pngSaveOptions, true, Extension.LOWERCASE);
            break;
=========================

It does. The standalone XML Export was only offered by itself
in the
registration incentives. Sorry.

Getting the path of a resource file inside the context

I am trying to migrate some of our applications running on OracleApplicaiton Server. We have data resource xml file needs to use in the applicaiton. In Oracle Application server we used to give the actual path of the xml file to load the xml file to the parsers since we know the path of the directories after deploying the application as an ear file. How can I get the path of the files in weblogic after deployment. If this is not supported what is the alternative to get the relative path of that xml file to load in ? The xml file is in the root folder of the context.
THanks
Suneesh

Hi Suneesh,
Please try enabling the <show-archived-real-path-enabled> Tag to TRUE ...And then everything will work fine with the following code:
context.getRealPath()
At domain level in config.xml. For example:
<web-app-container>
<show-archived-real-path-enabled>true</show-archived-real-path-enabled>
</web-app-container>
*****OR *****
At the web app level in weblogic.xml. For example:
<container-descriptor>
<show-archived-real-path-enabled>true</show-archived-real-path-enabled>
</container-descriptor>
For Archived Applications , It is always a best practice to use the getResourceAsStream() rather than using getResource().......Below code snippet should workout in 99% cases
InputStream stream=this.getClass().getClassLoader().getResourceAsStream("someXMLorPropfile.properties");
Thanks

In the new version of Numbers this option is not available. You will have to type the file name into the header yourself. You can post feedback to Apple using the menu item "Numbers > Provide Numbers Feedback"
or use Numbers2.3 which should be in the folder "/Applications/iWork '09" if you previously had it installed

Teststand 1.03 - How can I get the sequence file path into an expression?

The sequence file will be located at different locations on different computers. I need the base address of the sequence file to get to the correct limits file. How can I get the sequence file path into a string-local expression.
Thanks

As Ray described, the FindFile expression function and TS API method will seach all TS search directories and return to you the path of your file, assuming the file is located in the search directories.
If you just want the path of a TS file that you have a reference to then there is a faster, easier method. You can use the Path property of the PropertyObjectFile class. In the attached example I use an AcitiveX Automation adapter step to call Path on the property RunState.SequenceFile. This returns the path to the current executing sequence file. Note that if you have not yet saved the sequence file then the path will be empty. In a subsequence step I strip off the file name leaving the root path of the file.

How can I get the direction handles to show up for the Position attribute?

How can I get the direction handles to show up for the Position attribute?
I have CS3 and I did the formentioned test and was able to make the handles work for the scale attribute but they don't seem to show when editing the position values.
*I am in the graph editor looking at the "value graph"
*I select the keys and convert the keys to auto bezier (I also tried the ease in and out buttons)
*It changed the graph the way you might think (no longer linear) however the handles are not showing to edit further.
*I also tried using the "convert vertex tool" (part of the pen tool) and still no luck getting those handles.
*the handles only show up in the speed graph but that does me no good.
Please help!
THANKS

I don't have CS3 installed on any of my machines any more but your value graphs for position should look something like this:
There are no handles for position in the Graph editor. You adjust the position curve by editing the motion path in the composition window. Press the G key to bring up the pen tool, then use the modifier keys Crtl/Cmnd and Alt/Option to temporarily switch between select and convert vertex to adjust the paths. Changes will be reflected in the value graphs. You will get editable handles with scale and rotation because these are not spatial properties. Spatial properties, position, Anchor Point, all XY & Z coordinates are edited in the comp window or in the layer window after revealing the properties. IOW, you edit anchor point position paths by opening up the layer window and choosing Anchor Point from the display options.
The Manual isn't wrong. Here's a link to the live docs.

Given an alias created by the Finder, from the Unix prompt (e.g., in Terminal) how can I get the target of the alias?

In my Finder windows I have numerous aliases that point mostly to other folders. When in the Terminal, these aliases present as regular files. How can I get the target of an alias so that I can perform some operation, e.g., "cd", on the target?

This AppleScript demonstrates how to resolve the OS X alias and return a POSIX path for it
set af to choose file
tell application "Finder"
if the kind of af is "alias" then
set origFile to the POSIX path of ((original item of af) as text)
end if
end tell
display dialog origFile
