1. Check the thread: ps -ef|grep tomcat name (check whether your current project is running)
2. Kill the thread: kill process id kill the process (close a currently running tomcat)

7. Open the file chooser to upload the local file to the server: rz
8. Download the file from the server to the local: sz filename
9. Unzip the zip file: unzip filename.zip

View file contents
cat file1 View the contents of the file forward from the first byte
tac file1 View the contents of a file in reverse from the last line
more file1 View the contents of a long file
less file1 is similar to the 'more' command, but it allows the same reverse operation in the file as the forward operation
head -2 file1 View the first two lines of a file
tail -2 file1 to view the last two lines of a file
tail -f /var/log/messages see in real time what is being added to a file
