sed problem - replacement string should be same length as matching string.
Hi guys, I hope you can help me with my problem.
I have a text file that contains lines like this:
78 ANGELO -809.05
79 ANGELO2 -5,000.06
I need to find all occurences of amounts that are negative and replace them with x's
78 ANGELO xxxxxxx
79 ANGELO2 xxxxxxxxx
Note that the number of x's should match the number of characters replaced, that is, since -809.05 is 7 chars long, it should be replaced by 7x's. The x's should also be in the same position as where the original negative sign was to preserve the line spacing of the file.
Any idea how to do this? Thanks for your help.
