Shell Programming and Scripting

Hi,

I have a requirement like below.

client is sending the .txt filles.In that file we have 10 records but when I execute the below command it is showing 9 records.

Code:

klena20> wc -l sample_file.txt|awk '{print $1}'

It is showing the output as 9

But in a file records are 10. I found that in 10th record there is no hit to enter the line.might be this is the issue. To overcome this issue what we can do. Could you please suggest me. client is sending the files like this way only.

Thanks in advance

If there is no newline after the last record, then it will not be counted by wc -l
So it would be best to add an extra newline to the file (a proper Unix text file should have that).

Otherwise you may have better luck with

Code:

awk 'END{print NR}' file

Which would probably work, but you could perhaps run into an implementation of awk where this would not work.

So, how we can read the no. of records in a file without wc -l. Could you please help me out.

thanks

Another approach would be grep -c . sample_file.txt

Bad one if blank lines are permitted in the input file.

How about switching the position of awk and wc -l

awk '{print}' sample_file.txt | wc -l

??

Why use awk at all?

Code:

wc -l < sample_file.txt

Did you try Scrutinizer's proposal?
