How to Remove Control Characters? 1

[wellster34]

Hi,

I have a data file that contains Control Characters:

A|TEST^M
B|TESTING^M
...etc...

Is there a way to remove the Control Characters in the data file via a ksh unix script?


Thanks for your time.

tr -d "[:cntrl:]" < inputfile > outputfile

If the files were FTP'd from Windows to the UNIX box, try putting/getting the files in mode ascii, this will make sure the ^M characters are stripped on transfer.

If your OS supports it, man dos2unix or equivalent.

There is an extract process that creates the file. When that file is created it has the control characters.

Then we FTP transfer the file over to another unix server via a bin transfer. I just tried the FTP again with an ascii transfer and the control characters are still there?


I just tried the tr -d "[:cntrl:]" < inputfile > outputfile and it worked!!! The issue is that the lines are all merged into one continuous one.

So, maybe the control characters are required to keep the lines separate on each of their own lines...

Just to clarify... the file is created on a unix server and we transfer it to another unix server.
