How to count words in a line












3















I have a text file called "shoplist.txt" which one have:



drinks water cola fanta

fruit banana orange


And I want to get how many items per line I have. I'm able to extract drinks and fruit with function "cut" but how can I count how many words I have in each line?



My actually code is:



fileLine=`cat file.txt`

#Here I get each line saving it to fileLine

for line in $fileLine; do

 echo

((aux++))

done


But this code dosen't work because it save to %fileLine each work (drinks, then water,then cola,...)



How can I get the first line and then count the words on that line?






bash shell-script

If you can use awk, NF is the number of fields in the current line (by default, a field is a word delimited by any amount of whitespace).



Use



awk '{ print NF, $0 }' inputfile


With your sample input, this will print



4 drinks water cola fanta

3 fruit banana orange

  • The more cryptic awk '$0=NF" "$0' inputfile is a shorter solution.

In Bash and wc:



IFS=$'n'

while read line; do

    wc -w <<< "$line"

done < file.txt


wc counts lines, words, bytes in files. With a shell loop you can make it count words in a line.
