multitail:tldr:d195b

The command multitail is a Linux command used to monitor multiple log files simultaneously in a single terminal window. It provides the ability to follow and view real-time updates from multiple log files.

Here's a breakdown of the given command:

• multitail: This is the command itself.
• -s 2: This option sets the scroll rate to 2 lines per second. It determines how quickly the display of the log files scrolls.
• -sn 1,3: This option specifies which log files to display and in which order. In this case, it will display the first and third log files.
• ${mergefile}: This is a placeholder for the name or path of the file that contains merged log data. It will be displayed along with the other log files.
• -I: This option is used to ignore regular log files. It tells multitail to treat the specified files as text files instead of log files.
• ${file1} ${file2} ${file3} ${file4}: These are placeholders for the names or paths of the log files to be monitored. Replace them with the actual names or paths of the log files you want to monitor.

To summarize, the command multitail -s 2 -sn 1,3 ${mergefile} -I ${file1} ${file2} ${file3} ${file4} will open a multitail session in which it will display the contents of the specified log files (${file1}, ${file2}, ${file3}, ${file4}) along with the contents of ${mergefile}. The display will scroll at a rate of 2 lines per second, and only the first and third log files will be displayed. The -I option ensures that the specified files are treated as text files rather than log files.
