Think big and small, and then redirect.

Linux sometimes encounters a file that is so large that the keyword search exceeds the whole screen and cannot see everything. For example, a very large log file info.log, if we want to view all logs of a certain character, it can be the same as cat info.log | grep '1711178968'. If there are too many logs, you can add time and control the number of lines. You can also use the'> > 'instruction. Cat info.log | grep '1711178968' > > temp.log temporarily save the intermediate result and view the temp.log file page by page through more, less and other tools

If it is a log with a certain time range, you can still intercept the log according to the time:

/ / intercept logs for a certain period of time sed-n'/ 2018-10-25 17 25.log 30 root.2018 41According to Grammer 2018-10-25 21 21 purge 47 purl 47 hand-10-25.log > update.log

Intercept logs between 17: 30 and 21: 47 in log 25.

View through the more instruction.

Then / ${keyword} search, such as / 1711178968, n next, b last

The above linux search for large files to specify the content of the implementation method is the editor to share with you all the content, I hope to give you a reference, but also hope that you support more.
