I want to replace all occurrences of 1800 102 6022 with 1860 266 2666 in all files. I have different files in different directories which can contain 1800 102 6022.I am using:perl -pi.13.04.2016 -w -e s/\b1800 102 6022\b/1860 266 2666/g; /*.jsp which works for a single folder. I want to run this in the parent directory and apply it to all files.
