4/13/2023 0 Comments Powershell regex replace![]() Also, feel free to suggest a better regex if that would help. The following regex seems to do the job of finding the larger strings where I need to make replacements, but I don't know what functionality in Powershell ( replace?) to use to just replace the substring of the results. I'd like the resulting text to be as follows, where you'll note that only the first 6 lines should change: A 2180 1830 12 0 3 3 TEST=C1604Ī 1090 1970 12 0 3 3 TEST=CSA1614 <- Second instance of '14' shouldn't changeĪ 1090 1970 12 0 3 3 TEST=CSA140 <- Shorter numbers shouldn't changeĪ 1090 1970 12 0 3 3 TEST=CSA14001 <- Longer numbers shouldn't change To clarify with an example, suppose that in the following test text I want to find only the 14xx-numbered instances like "TEST=*1404" in the following text, and replace the 14xx with 16xx? A 2180 1830 12 0 3 3 TEST=C1404 ![]() Can this be done in one smooth step like above? Or do you have to extract each match of the larger regex, search and replace within it, and then somehow stick that result back into the original text? ![]() ![]() Now I'm trying to figure out how to replace a subsection of each match of a regex. Using Powershell, I know how to search a file for a complicated string using a regex, and replace that with some fixed value, as in the following snippet: Get-ChildItem "*.txt" |
