[Solved] Replace yesterday date with today's date except from the first line
Hello,
I have a file like this:
2012112920121130
12345620121130msABowwiqiq
34477420121129amABamauee
e7748420121130ehABeheheei
in case the content of the file has the date of yesterday within the lines containing pattern AB this should be replaced by the current date. But if I use "sed", it will replace all the occurrences and I want to leave the first line as it is.
How can I do that?
Any help is really appreciated.
