Remove Line Feed from passing into variables.

[abarry1]

Good Afternoon All,

I am trying to read a flat file. The contents of the flat file look like the following:

/opt/local/GoAnywhere_Services/userdata/workspace/1000000023197
/opt/local/GoAnywhere_Services/userdata/workspace/1000000022986
/opt/local/GoAnywhere_Services/userdata/workspace/1000000022985
/opt/local/GoAnywhere_Services/userdata/workspace/1000000023195
/opt/local/GoAnywhere_Services/userdata/workspace/1000000022981
/opt/local/GoAnywhere_Services/userdata/workspace/1000000023198
/opt/local/GoAnywhere_Services/userdata/workspace/1000000023200

I am then using a for-each loop, and setting up a variable:

<setVariable name="folders" value="${folder[1]}${system.carriageReturn}" version="2.0" />

I am then setting up the command structure that I am trying to accomplish. This command will go out and delete the folders that were provide in the flatfile:

<setVariable label="SetVar: Cmd" name="Cmd" value="rmdir "${folders}"" version="2.0" />


<print label="Create Command File" file="${system.job.workspace}/CrtDelete.sh" append="false" version="1.0">
<![CDATA[${Cmd}]]>
</print>


<exec label="Make Command Executable" executable="chmod" workingDir="${system.job.workspace}" version="1.0">
<arg value="+x" />
<arg value="${system.job.workspace}/CrtDelete.sh" />
</exec>

<exec label="Delete Empty Directory" executable="${system.job.workspace}/CrtDelete.sh" workingDir="${system.job.workspace}" version="1.0" logLevel="debug" />

</forEachLoop>

The problem I am having is that the variable is adding a bunch of spaces or a line feed and it is adding a \r to the end of the folder name, which is causing the script to fail saying that is not a valid folder.

How can I get the file to read each line separately to feed the folder names?

Here the the logs:

ABarry1,

Check out the following link in the forums ... I believe it will give you the information you're looking for, as well as a project to help you accomplish what you're trying to do.

Working with Folder Variables

Utilizing this utility, you then have can read the "rowset" (of folder variables) then delete the desired folders with the "delete" task.

Rick,

Thanks. That is actually the project that I have been working with. I was just having an issue with the line feed causing the problem. I just added a search and replace on the file to remove the line feed and I was able to get it working with no problems.

Thanks for your reply.
