Use nl like this   nl filename   From man nl      Write  each  FILE to standard output  with line numbers added   With   no FILE  or when FILE is -  read standard input

wc -l file name for eg  wc -l file txt it will give you the total number of lines in that file for getting last line use tail -1 file name

User · Answer

To count all lines use     wc -l file   To filter and count only lines with pattern use     grep -w  pattern  -c file     Or use -v to invert match     grep -w  pattern  -c -v file    See the grep man page to take a look at the -e -i and -x args

wc -l file txt   cut -f3 -d      Returns only the number of lines

User · Answer

Use wc   wc -l  lt filename gt    This will output the number of lines in  lt filename gt      wc -l  dir file txt 3272485  dir file txt   Or  to omit the  lt filename gt  from the result use wc -l  lt   lt filename gt      wc -l  lt   dir file txt 3272485   You can also pipe data to wc as well     cat  dir file txt   wc -l 3272485   curl yahoo com --silent   wc -l 63

wc -l does not count lines   Yes  this answer may be a bit late to the party  but I haven t found anyone document a more robust solution in the answers yet   Contrary to popular belief  POSIX does not require files to end with a newline character at all  Yes  the definition of a POSIX 3 206 Line is as follows      A sequence of zero or more non-  lt newline gt  characters plus a terminating  character    However  what many people are not aware of is that POSIX also defines POSIX 3 195 Incomplete Line as      A sequence of one or more non-  lt newline gt  characters at the end of the file    Hence  files without a trailing LF are perfectly POSIX-compliant   If you choose not to support both EOF types  your program is not POSIX-compliant   As an example  let s have look at the following file   1 This is the first line  2 This is the second line    No matter the EOF  I m sure you would agree that there are two lines  You figured that out by looking at how many lines have been started  not by looking at how many lines have been terminated  In other words  as per POSIX  these two files both have the same amount of lines   1 This is the first line  n 2 This is the second line  n   1 This is the first line  n 2 This is the second line    The man page is relatively clear about wc counting newlines  with a newline just being a 0x0a character   NAME        wc - print newline  word  and byte counts for each file   Hence  wc doesn t even attempt to count what you might call a  line   Using wc to count lines can very well lead to miscounts  depending on the EOF of your input file    POSIX-compliant solution  You can use grep to count lines just as in the example above  This solution is both more robust and precise  and it supports all the different flavors of what a line in your file could be    POSIX 3 75 Blank Line POSIX 3 145 Empty Line POSIX 3 195 Incomplete Line POSIX 3 206 Line     grep -c   FILE

If all you want is the number of lines  and not the number of lines and the stupid file name coming back    wc -l  lt   filepath filename ext   As previously mentioned these also work  but are inferior for other reasons      awk  END print NR   file         not on all unixes sed -n      file                  GNU sed  also not on all unixes grep -c      file                overkill and probably also slower

I know this is old but still  Count filtered lines  My file looks like   Number of files sent Company 1 file  foo pdf OK Company 1 file  foo csv OK Company 1 file  foo msg OK Company 2 file  foo pdf OK Company 2 file  foo csv OK Company 2 file  foo msg Error Company 3 file  foo pdf OK Company 3 file  foo csv OK Company 3 file  foo msg Error Company 4 file  foo pdf OK Company 4 file  foo csv OK Company 4 file  foo msg Error   If I want to know how many files are sent OK   grep  OK   lt filename gt    wc -l   OR  grep -c  OK  filename

The tool wc is the  word counter  in UNIX and UNIX-like operating systems  but you can also use it to count lines in a file by adding the -l option   wc -l foo will count the number of lines in foo  You can also pipe output from a program like this  ls -l   wc -l  which will tell you how many files are in the current directory  plus one

Redirection Piping the output of the file to wc -l should suffice  like the following   cat  etc fstab   wc -l   which then would provide the no  of lines only

I ve been using this   cat myfile txt   wc -l   I prefer it over the accepted answer because it does not print the filename  and you don t have to use awk to fix that  Accepted answer   wc -l myfile txt  But I think the best one is GGB667 s answer   wc -l  lt  myfile txt  I will probably be using that from now on  It s slightly shorter than my way  I am putting up my old way of doing it in case anyone prefers it  The output is the same with those two methods

This drop-in portable shell function     nbsp  works like a charm  Just add the following snippet to your  bashrc file  or the equivalent for your shell environment      ---------------------------------------------    Count lines in a file       1   path to file      EXAMPLE USAGE   count file lines  HISTFILE    --------------------------------------------- count file lines         local subj   wc -l  1      subj    subj   1        echo   subj     space           This should be fully compatible with all POSIX-compliant shells in addition to bash and zsh

wc -l  lt filename gt   This will give you number of lines and filename in output   Eg   wc -l  24-11-2019-04-33-01-url creator log  Output  63 24-11-2019-04-33-01-url creator log  Use  wc -l  lt filename gt  cut -d   -f 1  to get only number of lines in output   Eg    wc -l  24-11-2019-04-33-01-url creator log cut -d   -f 1  Output  63
