clearcase appends weird stuff - clearcase

I am getting some weird characters at the end of some of my files.
The files are not checked out when this occurs and if I check them out and undo the check-outs these characters disappear.
The problem is it does this with files at random, not the same ones all the time, but a number of files here and there. One of the consequenses of these occurances is that eclipse projects cannot be loaded since the .project-file is seen as corrupt. Any suggestions as to why this happens?
I am sorry I cannot post any images. However, in text shown in notepad++ it is written as:
....
....
<last_line>[nul][nul][nul][nul][nul][nul][nul]...
by the way, [nul] has the value 0x00.

It could be an encoding issue, like one described in this technote, where Diffmerge incorrectly selects encoding based on locale.
You can check their encoding by editing them in Notepad++.
Check also your ClearCase Unicode Type Manager.
Depending on your ClearCase version, you also had issue with the magic file.
Finally, check if you have some corrupt container associated with those files:
See technote swg21222072 Type manager text_file_delta failed create_version operation.

ClearCase automatic merge puts the content of the file in single line

We are using ClearCase UCM INTEROP setup in our organization.
We are facing a strange issue where the file content in put on one line while doing a merge and hence causing the build to fail.
Does anyone know why this is happening?
There is another thing that can sneak up and bite you here.
View text modes -- there are 3 for ClearCase, and you can get unexpected results if you use the wrong 2.
Those modes are:
insert_cr (also known as msdos). This inserts carriage returns on cleartext creation (file open/edit/etc.) and strips them at checkin.
transparent. Doesn't make any changes to the line terminations.
strip_cr. This converts Windows line terminations to Unix ones on cleartext creation. It then re-inserts them on checkin.
If you use strip_cr for unix views, and insert_cr for Windows ones, you will have all kinds of line termination issues. And in some cases this can break builds.
You need to use the 2 that are adjacent to one another on the list above. With Windows using either insert_cr and unix "transparent". Or Windows "transparent" and unix strip_cr.
You may want to look at the problem file in another editor (notepad++ is one that handles both line termination styles well) and see whether you have Unix or Windows line terminations.
It would also help to know the platform where the merge was attempted. If it was done on Windows, then #VoC's steps will work as they call the Windows GUI text merge tool. You may want to try the same thing using the Windows/Unix CLI merge tool (cleardiff) if the files are "text_file" elements. We have seen cases where the 2 CLI and GUI merge tools behave differently.
It depends on:
what "put on one line while doing a merge" means (extra line added, or the all text is in one line, which would mean \n isn't treated as a newline character)
the type of file being merge (text, xml, binary, ...), as the merge manager involved would differ.
Start by trying to reproduce the issue, as explained in this technote:
Copy the "base" version into base.txt.
Copy the "from" version into from.txt and copy the "to" version into to.txt.
Run the following command:
cleardiffmrg -out foo.out -base base.txt from.txt to.txt
See if ignoring whitespaces helps:
cleardiffmrg -blank_ignore -out foo.out -base base.txt from.txt to.txt.
Check your text modes associated with the view in which you are doing the merge.
Try and make sure the newline sequence used in both versions of the file is the same (\n for instance, both in Windows and Unix)

Understanding compile errors due to copying code from a doc file and not a txt file

SITUATION:
My instructor for my micro-controller class refuses to save sample code to a text file and instead saves it to a word document file instead. When I open up the doc file and copy/paste the code into my IDE "CodeWarrior" it causes errors upon compile time.
I am having to rewrite all the code into a text editor and then copy/paste it into my IDE.
MY UNDERSTANDING:
I was told to always save code as a text file because when you save code as a word document file it will bring in unwanted characters when your copy/pasting the code into your IDE for compiling.
MY QUESTIONS TO YOU:
1.)
Can someone explain this dilemma to me so I can understand it better? I would like to present a better case next time when I receive errors and to also know more about what is happening.
2.)
Is it possible to write a script that will show me all the characters that are being copied and pasted into a file when the code is coming from a word document vs. a text file? In otherwords is there a program that will allow me to see what is going on between copying/pasting code from a word doc file versus a txt file?
Saving source code as a Word document is just silly. If your instructor is insisting on this, chances are no matter how well-reasoned and thorough your argument, they're not going to listen. They're beyond help.
However, to answer your questions: 1) It depends on what you're pasting the thing into. Programs that copy onto the clipboard usually make the data available in several different formats, ranging from their own internal format to plain ASCII text, to maximize compatibility so that the data can be pasted into pretty much any target program. Most text editors will only accept the plan-text version, in which case no extra characters should be transferred. However if your text editor supports RTF or HTML, this may not be true. I'm not sure what CodeWarrior supports but it is certainly possible.
A workaround if this is the case: First paste into a PURE text editor like Notepad. Then copy from Notepad into CodeWarrior. This should eliminate any hidden formatting. As shoover said above, make sure double-quotes " are really double-quotes and not the fancy left- and right-specific quotes that Word sometimes uses.
Use a hex editor like XVI32 to see the raw contents of the file, including nonprinting characters. Or use a text editor with support for showing nonprinting characters (vi/vim, etc.).
I'm studying C and I've just had the same problem. When coping a piece of code from a PDF file and trying to compiling it, gcc would return a serie of errors. Reading the answer above I had an idea: "What if I converted the utf8 into ascii?". Well, I found a website that does just that (https://onlineutf8tools.com/convert-utf8-to-ascii). But instead of also converting the utf8 characters into ascii, it showed them as hexadecimals (Copying from the website to the text editor you can see it better). From there i realised that the problem were mostly the quote marks "".
I then copied the ascii "translation" into my code editor (I must add that it worked fine with Sublime, while VScode read the same utf8 code as it was in the original file, even after cp from the website) and replaced all the hex with the actual ascii characters that were needed to compile the code properly. I used the function find and replace from my editor to do it. I must say that it wasn't very fast doing it. But I believe that in some cases, if the code you're trying to copying is too long, doing it the way I've just described could be faster than rewriting the entire code.

A simple log file format

I'm not sure if it was asked, but I couldn't find anything like this.
My program uses a simple .txt file for log purposes, It just creates/opens a file and appends lines.
After some time, I started to log quite a lot of activities, so the file became too large and hardly readable. I know, that it's not write way to do this, but I simply need to have a readable file.
So I thought maybe there's a simple file format for log files and a soft to view it or if you'd have any other suggestions on this question?
Thanks for help in advance.
UPDATE:
It's access 97 application. I'm logging some activities like Form Loading, SELECT/INSERT/UPDATE to MS SQL Server ...
The log file isn't really big, I just write the duration of operations, so I need a simple way to do this.
The Log file is created on a user's machine. It's used for monitoring purposes logging some activities' durations.
Is there a way of viewing that kind of simple Log file highlighted with an existing tool?
Simply, I'd like to:
1) Write smth like "'CurrentTime' 'ActivityName' 'Duration in milliseconds' " (maybe some additional information like query string) into a file.
2) Open it with a tool and view it highlighted or somehow more readable.
ANSWER: I've found a nice tool to do all I've wanted. Check my answer.

The 3 W's :
When, what and where.
For viewing something like multitail ("tail on steroids") http://www.vanheusden.com/multitail/
or for pure ms windows try mtail http://ophilipp.free.fr/op_tail.htm
And to keep your files readable, you might want to start new files when if the filesize of the current log file is over certain limit. Example:
activity0.log (1 mb)
activity1.log (1 mb)
activity2.log (1 mb)
activity3.log (1 mb)
activity4.log (205 bytes)
A fairly standard way to deal with logging from an application into a plain text file is to:
split the logs into different program functional areas.
rotate the logs on a daily/weekly basis (i.e. split the log on a size or date basis)
so the current log is "mylog.log" or whatever, and yesterday's was "mylog.log.1" or "mylog.ddmmyyyy.log"
This keeps the size of the active log manageable. And then you can just have expiry rules so that old logs get thrown away on a regular basis.
In addition it would be a good idea to have different log levels for your application (info/warning/error/fatal) so that you're not logging more than is necessary.
First, check you're only logging things that are useful.
If it's all useful, make sure it is easily parsable by tools such as grep, that way you can find the info you want. Make sure you have the type of log entry, the date/time all conforming to a layout.
Build yourself a few scripts to extract the information for you.
Alternatively, use separate log files for different types of entries.
Basically you better just split logs according to severity. You'll rarely need to read all logs for the whole system. For example apache allows to configure error log and access log, pretty obvious what info exactly they have.
If you're under linux system grep is your best tool to search through logs for specific entries.
Look at popular logfiles like /var/log/syslog on Unix to get ideas:
MMM DD HH:MM:SS hostname process[pid]: message
Example out of my syslog:
May 11 12:58:39 raphaelm anacron[1086]: Normal exit (1 job run)
But to give you the perfect answer we'd need more information about what you are logging, how much and how you want to read the logs.
If only the size of the log file is the problem, I recommend using logrotate or something similar. logrotate watches log files and, depending on how you configured it, after a given time or when the log file exceeds a given size, it moves the log file to an archive directory and optionally compresses it. Then the original log file is truncated. For example, you could configure it to archive the log file every 24 hours or whenever the files size exceeds 500kb.
If this is a program, you might investigate apache logging libraries (http://logging.apache.org/) Out of the box, they'll give you a decent logging format out of the box. They're also customizable, so you can simplify your parsing job.
If this is a script, see some of the other answers.

I've found it here. Filter is better, than in mtail. There's an option of highlighting just adding a string and the app is nice and readable. You can customize columns as you like.

how to open .d01 foxpro file

I am building a basic POS app for my cousin's pharmacy store so that he can dump the software he is currently using and save on license cost.All the medicines name which he has painfully entered into the software have been stored in a file with .d01 extension.
What i want is a way to read the contents of the .d01 file programmatically so that i can import the name of the medicines into my app.
The s/w from which my cousin uses is built in Foxpro(coz i see a lot of .cdx,.idx,.dbf files) and the file which i want to import is with .d01 extension. when i open the file in notepad it is something like this
http://img192.imageshack.us/img192/5528/foxpro.jpg
So I assume its somekind of database table or something. So can anyone please help me in reading this file, as i am not at all aware of foxpro.
Thanks a lot in advance to all those who take out time to reply.
hey guys thank you very much for replying so promptly.. I tried the solution suggested by Otávio and it worked, i will now write a small utility to read the dbf.
It has a good chance of being just a regular .dbf file. Copy it somewhere safe, change the extension to dbf and see if you can open it from foxpro.
Although it may have .cdx files, the actual paste of the file does not appear to be a visually recognizable header format of a VFP table... even if part of a database container. The characters around each column name don't look right. It may be from another language that also utilized "Compound Indexes". I even saw an article about Sybase's IAnywhere too. If worst-case scenario, and it is determined to be a possible fixed-length per row and no dynamic column sizes, you might take the file, strip off what appears to be the header and leave just the data and stream read it in based on how many constant characters are determined for the length. yeah, brute force, but just an option. Again, it doesn't LOOK like a VFP table.
BTW, what is the name of the software he is using... I'd look into that to see if any other type of indication to its source.
It looks sort of like a DBF file - maybe Clipper or something.

TBC files from an old and unknown database system

I have a bunch of *.TBC files from a very old application that runs in MS-DOS called TURBOLAB. Anyone know which DB System use files with a TBC extension.
I've tried renaming the files to *.dbf to check if they are dBase files with no luck.
Any idea?
Judging by the application and era (old MS-DOS) *.tbc is probably a fixed length binary record format written by the application's developers.
Try opening up the file in a text editor like TextPad first and if you can read the contents, if so I have a fixed length text file reader that you can adapt to your needs. If you cannot you may need to determine field lengths and data types through trial and error.
Also, are there associated files for each *.tbc? A paired file could indicate field lengths and data types (or that information could be stored at the top of a *.tbc file itself).
I Googled this: FlexPro. I hope it helps. Sounds pricey, I hope your data is worth it.
Judging by the application and era
(old MS-DOS) *.tbc is probably a fixed
length binary record format written by
the application's developers.
I think you are right. Unfortunately there are no matching file names. If each of those files is a 'table', there are like ~150 tables in this database. Too much work for such an old app. I guess my customer will have to start from scratch using my app.
Thanks anyway for your help.
