Counting number of TE in a file

Question

[yasjas]

Hello everyone,

I am totally new in this field, I would like to count the number of for example "LINE" in my file that I copied it below(a piece of it). Does anyone know how to extract only those elements and make a count?

Thank you for your answers

Answer 1

[TriS]

In R you can do it like this

m <- read.table("yourFile.txt")
sum(m$V7 == "LINE")

Thank you for your answer TriS it was really helpful :-)

In Linux:

grep LINE filename | wc -l

[Prakki Rama]

Slight change: grep -cw "LINE" filename :)
