Edit an existing text file

I have tried the few posts I have found on editing an existing text file, but it doesn’t work in my case.

I need to add this new line:

tw.proxy.host=compname.domain.com

To the bottom of a text file that has this existing content:

  1. AGENT Properties
  2. The Properties in this section are unique to the “agent.properties” file.

space.bootstrapables=station

tw.agent.changeBlockSize=500

tw.agent.taskPriority=4

tw.rpc.exec.threadPoolSize=4

tw.agent.queueMax=10

sun.net.client.defaultReadTimeout=1200000

sun.net.client.defaultConnectTimeout=1200000

sun.rmi.transport.tcp.threadKeepAliveTime=5000

tw.server.host=compname2.domain.com

tw.server.port=9898

When I try the action script example here: http://forum.bigfix.com/viewtopic.php?id=3850

This is the output I get (It mashes the original file all togther, and then appends the new line at the bottom):

  1. AGENT Properties# The Properties in this section are unique to the “agent.properties” file.space.bootstrapables=stationtw.agent.changeBlockSize=500tw.agent.taskPriority=4tw.rpc.exec.threadPoolSize=4tw.agent.queueMax=10sun.net.client.defaultReadTimeout=1200000sun.net.client.defaultConnectTimeout=1200000sun.rmi.transport.tcp.threadKeepAliveTime=5000tw.server.host=compname2.domain.comtw.server.port=9898

tw.proxy.host=compname.domain.com

This breaks the application. I need to keep it in it’s original format, with the new line at the bottom.

Thanks

Here is one way to do it that should preserve your file structure.

delete __appendfile

delete update.bat

appendfile echo tw.proxy.host=compname.domain.com >> drive:path\agent.properties

copy __appendfile update.bat

wait update.bat

This approach works especially well when paired with relevance substitution. In my environment, I built and/or edit a lot of properties and ini files on the fly that are customized to the machine/location/brand/etc.

appendfile echo property = {substitution for some local attribute} >> app_setup.ini

rmnetops,

In that other example post, it was written as…

appendfile {concatenation of lines of file (parameter “filename”) & “%0d%0a” & “some new text” & “%0d%0a”}

I think you’re looking for something like…

appendfile {concatenation “%0d%0a” of lines of file (parameter “filename”) & “%0d%0a” & “some new text” & “%0d%0a”}

What’s happening is you’re reading the lines of a file and concatenating them together without a CRLF, which would be the separator. That’s probably why it got all jumbled together.

Both methods work.

Thanks!

I made a minor correction above. I should have said contatenation “%0d%0a”. I always prefer CRLF, not LFCR.

Glad it worked.
