Now we can run the example sed command below to remove white space from the end of the line of each line. We will use -i command line to do an in place file edit/update for this example to permanently make the changes:sed -i 's/[[:blank:]]*$//' os.txtNow...

The following solution is for more complex examples of (d), such as: not all fields contain "double-quote" marks, or the presence of embedded "double-quote" marks within fields, or extraneous whitespace around field delimiters. (Thanks to Greg Ubben for this script!) # sed script to conve...
If there is no whitespace, particularly carriage-return, at the end of the line, it is expected to function properly. To determine the actual end of the line, usecat -veton the file, which displays a $ symbol. With the use of the option-i, you can update the file by combining your ...
