1. Redirect Output To File C#

To write the output of a command to a file, there are basically 10 commonly used ways. Overview:Please note that the n.e. In the syntax column means 'not existing'.There is a way, but it's too complicated to fit into the column. You can find a helpful link in the List section about it. visible in terminal visible in file existingSyntax StdOut StdErr StdOut StdErr file no yes yes no overwrite no yes yes no append 2 yes no no yes overwrite2 yes no no yes append & no no yes yes overwrite& no no yes yes append tee yes yes yes no overwrite tee -a yes yes yes no append n.e.

If the file already exists, the new data will get appended to the end of the file.command tee output.txtThe standard output stream will be copied to the file, it will still be visible in the terminal. If the file already exists, it gets overwritten.command tee -a output.txtThe standard output stream will be copied to the file, it will still be visible in the terminal. If the file already exists, the new data will get appended to the end of the file.(.)Bash has no shorthand syntax that allows piping only StdErr to a second command, which would be needed here in combination with tee again to complete the table. If you really need something like that, please look at for some ways how this can be done e.g. By swapping streams or using process substitution.command & tee output.txtBoth the standard output and standard error streams will be copied to the file while still being visible in the terminal. If the file already exists, it gets overwritten.command & tee -a output.txtBoth the standard output and standard error streams will be copied to the file while still being visible in the terminal. If the file already exists, the new data will get appended to the end of the file.

Somecommand tee command.log and somecommand command.log have the issue that they do not save the command output to the command.log file in real-time.To avoid that issue and save the command output in real-time, you may append unbuffer, which comes with the expect package.Example: sudo apt-get install expectunbuffer somecommand tee command.logunbuffer somecommand command.logAssuming log.py contains: import timeprint('testing')time.sleep(100) # sleeping for 100 secondsyou can run unbuffer python log.py tee command.log or unbuffer python log.py command.logMore information.

I have look very hard indeed.I want to redirect child process's output into file, but the examples you provided make use of pipes, which I think is unnecessary. It should be able to do without pipes, right? I do find somebody sucess.

I copy their examples, but they didn't work, as Imention above.Well I end up with pipes finally. The problem is, I have to create a thread to deal with the pipes otherwise the buffer may be full and child processes be jamed. Multithread makes the program more complicated which should not be necessary.
