UNIX for Dummies Questions & Answers

Hi,

in a file, i have records as below:

Code:

123|62|absnb|267629
123|267|28728|uiuip
123|567|26761|2676

i want to remove the non printable characters after the end of each record.
I guess there are certain charcters but not visible.

i don't know what character that is exactly.

I used to use below command while getting outputs from unix commands:

Code:

sed -e '/^[\t]*//'

In this case i don't know what's the character.
How i can remove those characters?
Else is there any command to dispaly the ascii value for each character inside the file,?
so that we can trace out that character.

Thanks

Is the file in DOS format? Open in vi and check if you see ^M at the end of each line. If so, do this: :%s/<ctrl + V + M>//g

use

Code:

 
cat -v filename

The above command will show the non printable characters.

Or use

Code:

 
od -c filename
