I have a text file which has over 60MB size. It has got entries in 5105043 lines, but when I am doing wc -l it is giving only 5105042 results which is one less than actual.

    The last line in your file is probably missing a newline ending. IIRC, wc -l merely counts the number of newline characters in the file.

    If you try: cat -A file.txt | tail does your last line contain a trailing dollar sign ($)?

    EDIT:

    Assuming the last line in your file is lacking a newline character, you can append a newline character to correct it like this:

    printf "\n" >> file.txt
    

    The results of wc -l should now be consistent.
