linux grep command – grep only show match
May 26, 2019
When we search for content, sometimes we just need to show matching content.
At this time we can use the grep command.
linux grep
➜ ~ grep 'line-number' test4.txt
You can also display the line number where the matching content is located.
linux grep -n
➜ grep -n 'line-number' test4.txt
Of course, you can also display the upper N lines, the lower N lines, or the upper and lower N lines of the line where the matching content is located.
linux grep -n -C
Show num lines before and after matching – grep -C
➜ grep -n -C 3 'line-number' test4.txt
Grep -C More info: grep show lines before and after
