I know how to use awk to search some expressions like five consecutive numbers, [0-9][0-9][0-9][0-9][0-9], this is easy.
However, how do I make awk print the pattern that is been matched?
For example:
input: usa,canada99292,japan222,france59664,egypt223
output:99292,59664
To keep the forums high quality for all users, please take the time to format your posts correctly.
Use Code Tags when you post any code or data samples so others can easily read your code.
You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags and by hand.)
Avoid adding color or different fonts and font size to your posts.
Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.
Be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.
because within each column, the field separator actually changes to space
Is it possible to have multiple field separator in place simultaneously, in this case: space and comma. If this is possible, then your code would work .
