问题 I'm trying to write a program that connects via SSH to a remote Linux server using Java. I've found a number of examples online to do this using the JSch package, but they're mostly for issuing a single command to the server right after authentication.

问题 I have lots of text files and need to put a header on each one of them depending of the data on each file. This awk command accomplishes the task: awk 'NR==1{first=$1}{sum+=$1;}END{last=$1;print NR,last,"L";}' my_text.file But this prints it on the screen and I want to put this output in the header of each of my file, and saving the modifications with the same file name.
