Common commands in Linux O & M Analysis

In addition to the omnipotent vi, you generally need to write down the following command

View File Content: cat

Display files by PAGE: more, less
Show file header and tail: tail head
Content sorting: sort
Character statistics: wc
View duplicate rows: uniq
String SEARCH: grep
File Search: find
Archive: tar
URL access tool: curl

If you are familiar with the above commands, you can use the combination of boxing, for example, to view the most time-consuming page:

Cat file name | sort-k 2-n-r (sort columns) | head-10

Further, we need to use sed and awk for shell programming.
