Josh “Yoshi” VickersonWhat's the easiest way for me to script moving the last line of a text file to the Nth line? I have a whole directory full of files that need the exact same treatment.
Update: My solution in replies!
tkissing@josh Assuming N is the same for all files, maybe a two-step combo of sed and tail? Eg for N=6
sed -i "6i $(tail -n 1 $file)" && sed -i '$d' $file
Untested, probably totally wrong if you are on a Mac, will most certainly fail if the last line contains a $ etc
I'm also sure some professional sysadmin will cry over this "obviously bad idea"
@tkissing My solution was very similar, but using vim!
I knew enough about the content (already mostly normalized via many regex and various find/replace steps) that I knew for sure every file was the same.
Worked really well for what I needed, and a super useful thing to know how to do!
