How to remove a character in a file??

I'm not getting how to remove a character from a file.Could anyone post a method to do this?Any help would be appreciable.

Ohhh... and one more thing... unless you're really unlucky, a few "extranious trailing nulls" won't make a jot of difference to the size of the file on disk, each each file "fills" whole blocks anyway, which is 1K (I think) on both fister and *nix... unless of course we're talking "lots" of trailing-nulls, or lots-and-lots of files.

How to remove a roll back segment file in 8.1.7

Hi,
How to remove a roll back segment file in 8.1.7 ?
My RBS tablespace has two datafiles, how can I delete one of them ?
Thank you.

You would
a. Create a new tablespace to hold rollback segments
b. Create rollback segments in the new tablespace
c. Bring the new rollback segments online and the old rollback segments offline
d. Wait for all the old rollback segments to go offline (they'd be in PENDING OFFLINE if there are active transactions)
d. Drop the old rollback segments
e. Drop the old rollback tablespace -- after confirming that it has NO active rollback segments and NO OTHER segments at all
f. Modify your init.ora to specify the new rollback segments in the "rollback_segments=" parameter
If you want to switch back to the old tablespace name and segment names, you'd do steps a to e and then run them again to recreate the old tablespace name (with 1 datafile, excluding the one you want to drop) and segment names.

How to remove source link in PDF file

Hello,
I want to create pdf files of all newsletters our organization has sent out for the past year. I took a template from the software we use for sending out our newsletters. I saved this template as an htm file on my desktop. Then I used acrobat pro to create a new pdf file from a web page. It comes out perfectly, all links are working, no problems there. But on the left top of the document there is a link to where that file is stored on my pc. It looks like this:
file:///C|/Documents%20and%20Settings/..........
I hope somebody can tell me how I remove that link from there. I've been struggling with it for some time now.
Kind regards,
Lucas

In the dialog of 'Create PDF from Web Page'you can change the settings.

How to replace a character in a file using awk

Hello,
Does anyone has a sample script to replace a character in a file using awk?
Regards,
Edited by: slsam01 on Jul 15, 2012 12:56 PM

Hi
awk it's not best for this job.
For replace charecter - generaly use tr or sed
Example on awk:
awk -F<old_char> ' { for (i=1; i<NF ;i++ ) printf ( "%s<new_char>", $i ); print $NF }' <file>
#Replace "e" on "a" in /etc/hosts
awk -Fe ' { for (i=1; i<NF ;i++ ) printf ( "%sa", $i ); print $NF }' /etc/hosts
Regards.
PS. Same on *tr"
cat file | tr "e" "a"

How to put Chinese character in jar file by java.util.jar.Manifest?

Now I want to develop a simple package tool which can modify some property in manifest.mf of jar files,but the Manifest class's putValue method only can correctly save English character.why?
And how can I put Chinese character?
the code is:
Attributes ab = mf.getMainAttributes();
ab.putValue("agent-Name", agent);

Attribute values can contain any character and it will be UTF-8 encoded when written to the manifest, according to Javadoc.
What makes you think that this mechanism fails? What do you see instead of the Chinese character? And what tool/editor/program you use to see it? I did not try myself, but according to the Javadoc there should be no problem.

How to remove element namespaces in XML file using DOM or SAX?

Hi Guys,
I developed a JAVA mapping in XI to add name spaces for XML file, after mapping,name spaces xmlns="http://www.mro.com/mx/integration" and xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" were added correctly, but for some nodes, such as <Header> and <Content>, a name space xmlns="" was added automatically.Please check below files to compare.
It looks like be added automatically by XI. I didn't process anything for these nodes in JAVA program.
Now the issue is, how can I remove these redundant namespaces? Such as xmlns="".
Can I remove them using DOM or SAX in JAVA Mapping?
Thanks in advance.

Hi Milan,
Thanks for your replay.
Actually when I used module XMLAnonymizerBean to convert namespaces, the header of XML, such as <?xml version="1.0" encoding="UTF-8"?> was converted to format <?xml version='1.0' encoding='UTF-8'?>, quote was converted to single quote. Although I set parameter anonymizer.quote = ", it still didn't work, single quote appeared instead of quote.
I'm not sure why this happened. Can anyone help to clarify this?
Thanks
