How to ignore whitespace with diff?

To ignore whitespace changes when using the diff command, you can use the -w option. This option tells diff to ignore all whitespace differences, including spaces and tabs.

Syntax:

diff -w file1.txt file2.txt

Example:

If you want to compare two files, file1.txt and file2.txt, while ignoring whitespace changes, you would run:

diff -w file1.txt file2.txt

Additional Options:

• -b: This option ignores changes in the amount of whitespace (e.g., it treats a line with two spaces as equivalent to a line with one space).

  diff -b file1.txt file2.txt

• -B: This option ignores changes whose lines are all blank.

Using these options can help you focus on the actual content changes rather than formatting differences. If you have more questions or need further assistance, feel free to ask!
