it fixes the issue First, you only want column 7 from the passwd file. The usernames will just get in the way. Then sort and use the uniq command to count them:
code :
$ cut -d: -f7 /etc/passwd | sort | uniq -c
      2 /bin/bash
     24 /bin/false
      1 /bin/sync
      1 /usr/local/bin/fish
     16 /usr/sbin/nologin

Counting the number of lines in a UITextView, lines wrapped by frame size

like below fixes the issue This variation takes into account how you wrap your lines and the max size of the UITextView, and may output a more precise height. For example, if the text doesn't fit it will truncate to the visible size, and if you wrap whole words (which is the default) it may result in more lines than if you do otherwise.
code :
UIFont *font = [UIFont boldSystemFontOfSize:11.0];
CGSize size = [string sizeWithFont:font 
                      constrainedToSize:myUITextView.frame.size 
                      lineBreakMode:UILineBreakModeWordWrap]; // default mode
float numberOfLines = size.height / font.lineHeight;

File Output From C Program Behaving Strangely When Counting Lines

Any of those help It's probably some odd combination of return ('\r') and linefeed ('\n') characters.
Assuming you have the GNU Coreutils version of "tr", you can use these commands to count the number of each character in the file:
code :
tr -d -c '\n' FILE | wc -c

tr -d -c '\r' FILE | wc -c

Capturing output and counting its lines

Any of those help I'm now using a workaround by appending a fake line to the output; this way I can rely on the fact that one line will always be present, and this way the empty line is easily distinguishable from the one-line:
code :
r=$(find var/ -name var -printf "%p\n"; echo '==')
# appending additional line to be able to distinguish 0 from 1 found file
case "$(echo "$r" | wc -l)" in
  1)  # means 0 found files
    ...
  2)  # means 1 found file
    ...
  *)  # means more found files
    ...

How to get the number of characters or lines by the CHARACTER COUNTING and LINE COUNTING programs in C?

To fix this issue I just started writing C programs and I am taking help of The C Programming book written by Dennis Ritchie. When I tried to run the program for COUNTING characters or new lines, i was expecting some numbers as solutions but it didn't happen, instead it just allowed me to enter characters, with no value( of the number of lines/ characters) in return. I am new to programming. I would appreciate some help to get me through. , As you can see in the line
