Find the number of occurences of certain string sequences

I want to count the number of occurences of the IP address 192.168.1.10 in a text file using grep | wc grep | wc .

The command I use is:

cat ./capture.txt|grep "192.168.1.10"|wc -w

which returns 0, and I don't know why.

Here is the content of my .txt file:

give this a try:

grep -Fwo '192.168.1.10' file|wc -l
  • -F makes the grep take your pattern as literal string instead of regex
  • -w excludes 192.168.1.101 or 192.168.1.100
  • -o lists each match in a line. grep does line based match, if your pattern matched twice in a line, the result of occurrence count may be wrong.
cat ./capture.txt | grep "\b192\.168\.1\.10\b" -c
  • \\. search for dot, not any character
  • \\b match at the beginning or end of a word
  • -c return the number of occurrences
