output

I'm working on a little game using C++ with SDL2 using Code::Blocks 12.11 under Windows 7. I'm using the mingw32-gcc compiler and downloaded the standard precompiled Windows distribution of SDL2 (2.0.1 now) and use the i686-w64-mingw32 version. So far stuff is working, I'm getting graphical output and the SDL_ttf extension works too. The only thing that has never worked from the beginning is getting my stdout in a txt file from SDL as intended: Regardless of what I do, I NEVER get stdout.txt or stderr.txt anywhere, haven't seen those files created even once. The files also aren't created

I have some pipe. For example, I have this pipe: user@user:~$ cal | head -1 | grep -oP "[A-Za-z]+" For this pipe I get this result: September I want to store this result to a variable. I write the following commands: user@user:~$ cal | head -1 | month=$(grep -oP "[A-Za-z]+") | echo $month And I get the blank string. What is the problem? month=$(cal | head -1 | grep -oP "[A-Za-z]+") or month=$(date +%B) 来源： https://stackoverflow.com/questions/25710640/how-to-redirect-grep-output-to-a-variable

I am trying to copy a record in a table and change a few values with a stored procedure in SQL Server 2005. This is simple, but I also need to copy relationships in other tables with the new primary keys. As this proc is being used to batch copy records, I've found it difficult to store some relationship between old keys and new keys. Right now, I am grabbing new keys from the batch insert using OUTPUT INTO. ex: INSERT INTO table (column1, column2,...) OUTPUT INSERTED.PrimaryKey INTO @TableVariable SELECT column1, column2,... Is there a way like this to easily get the old keys inserted at the

I'm running multiple commands in my Linux shell at the same time, e.g. echo "Line of text 1" && echo "Line of text 2" && complexthing | xargs printf "complexspecifier" I want to redirect all output to file1 . I know I can add >file1 after each individual command but this seems bulky. How can I do this? exec >file1 # redirect all output to file1 echo "Line of text1" echo "Line of text2" exec > /dev/tty # direct output back to the terminal Or, if you are on a machine that doesn't have /dev/tty , you can do: exec 5>&1 > file1 # copy current output and redirect output to file1 echo foo echo bar
