Editor to share with you to use the logsave command in linux to save the output information to the specified log file, I believe that most people do not know much about it, so share this article for you to learn. I hope you will learn a lot after reading this article. Let's learn the method together.

The logsave program executes cmd_prog with the specified parameters and saves a copy of its output to logfile. If the include directory of the log file does not exist, logsave accumulates output in memory until it can be written out. A copy of the output is also written to standard output.

If the command prog is a single hyphen ("-"), then logsave will take its input from standard input and save it in a log file instead of executing the program, and logsave is useful for saving the output of the initial startup script until the / var partition is loaded, so the output can be written to / var/log.

Syntax format: logsave [parameters]

Common parameters:

-an append information to the specified log file-s displays log information and does not write to the file

[root@linuxcool] # logsave / tmp/logdir/logfile bash-c "sleep 2 position date"

Use the-a parameter to append information to the log file:
