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

  • Is the output of the awk script in the answer what you want to have? If not, what exactly do you want to get?

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.

            How to label and detect the document text images

            Image
            1 $begingroup$ This is what I mean as document text image: I want to label the texts in image as separate blocks and my model should detect these labels as classes. NOTE: This is how the end result should be like: The labels like Block 1, Block 2, Block 3,.. should be Logo, Title, Date,.. Others, etc. Work done: First approach : I tried to implement this method via Object Detection, it didn't work. It didn't even detect any text. Second approach : Then I tried it using PixelLink. As this model is build for scene text detection, it detected each and every text in the image. But this method can detect multiple lines of text if the threshold values are increased. But I have no idea how do I add labels to the text blocks. PIXEL_CLS_WEIGHT_all_ones = 'PIXEL_CLS_WEIGHT_all_ones' PIXEL_C...
