ProgrammingThis forum is for all programming questions.
The question does not have to be directly related to Linux and any language is fair game.

All true, except the two character program doesn't work when the first line is not blank, in which case that line should not be deleted. It's not clear from the OP if that is important or not.

Reason: typo
If the problem is to delete the first line from a file if and only if it is a blank line. If you know it is blank, entering "sed -i '1d' filename" is a quick and easy way to remember command to delete the first line on a particular file. Thanks for pointing it out though.
I will use "find ./ -type f -md5sum '{}'\; | sort | uniq -w32 -D >dupes" to locate duplicate files. After handling a duplicate, I'll enter "sed -i '1,2d'" in the console to delete the entries for the original and duplicate. Then I'll look at "head dupes" again. If you find a duplicated directory, you could use
"sed -i '/\/dirname\//d' to delete all entries containing that directory name.
