Clash Royale CLAN TAG #URR8PPP up vote 0 down vote favorite I was just going through the official bash repository(I don't usually do this) for something unrelated but noticed that bash 5 was already in beta. I was just curious about what's going to be new in bash 5 but couldn't find any information.

Shell way to get specific text based on condition

Image
Clash Royale CLAN TAG #URR8PPP up vote 0 down vote favorite Using shell script I am making a db call on database VM and I am getting and storing the query response into a .txt file. Which looks like below: X folder Check: Number of Files on X Outbound 17 Y folder Check: Number of Files on Y Outbound 17 Z folder Check: Number of Files on Z Outbound 18 Now for each of the X,Y and Z. I am basically receiving files(counts) on their respective locations. So I am expecting to get "18" files for each X,Y and Z. Now using shell I want to be able to know/store the folders for which I didn't receive 18 files. Example: here in the above case I should get that I am missing files for X and Y folders. Any help ??

Sorting nlog(sqrt(n))

Clash Royale CLAN TAG #URR8PPP up vote 1 down vote favorite A researcher claimed that she discovered a comparison-based sorting algorithm that runs in $O(nlog(sqrtn))$ . Given the existence of an $Omega(nlog(n))$ lowerbound for sorting, how can this be possible? Hint : It is possible. Don't waste time trying to disprove it. Just show why it is possible. algorithms share | cite | improve this question edited 3 hours ago Thinh D.
