[Shell] Linux calculates the number of times a string "sent IP" appears in a file.

I tested the product performance a few days ago and ran for several days.Program, Stopped today, because the program is not very stable, the test is complete, it is required to count how many times the program started. So I opened the log file and started to calculate it once. I found that it was too big and my eyes were exhausted. I thought this would not work. I had to make statistics on my computer. So I thought about it and wrote the following line of SH statements, so I had to make statistics. Write it to Bolg to prevent forgetting. (Fortunately, if you do not have a 4 m log file, it is estimated that you will not be able to find the path to go home after work)

The key is as follows.

 

Linux counts the number of times the string "sent IP" appears in a file: Cat nohup. log | grep "sent IP" | WC-l
