Searching files by number of lines in the file

[Philippe Carly]

I would like to find multiple files (I know how to do that) 
that don' have a specific number of lines (this I don't know).

More specifically, I have a directory which contains a large number of 
subdirectories, each containing (among other things) a fileinfo.php file.
I now that this fileinfo.php should have N lines. And I am trying to locate 
files that have more or less than N lines to search for potential problems.

thanks for your help.

Re: Searching files by number of lines in the file

['Holger Bartel' via BBEdit Talk]

Hi, 

Absolutely untested, but maybe something like counting number of line ends 
followed by a line break/return as in search for: $\r{number_of_lines} or 
$\n{number_of_lines} could work? Grep needs to be turned on for that, in case 
that’s new. 

I think $\n{min, max} should find those that have less or more lines if I’m not 
mistaken. 

Hope this helps,
Holger

Re: Searching files by number of lines in the file

[Sam Hathaway]

I don’t know how to do it with BBEdit, but this shell command will 
work:


`find /path/to/files -name fileinfo.php -exec sh -c 'test `cat {} | wc 
-l` -ne N’ \; -print`


Replace `/path/to/files` with the path to your directory and `N` with 
your “N”.


Hope this helps.

Hello Holger,
thank you for your feedback...
Unfortunately BBEdit doesn't seem to understand the {x,y} bit of the GREP 
search

Re: Searching files by number of lines in the file

[Sam Hathaway]

Folks,

Philippe pointed out that my mail client may havr munged the quotes in that 
command line. It should be:


find /path/to/files -name fileinfo.php -exec sh -c 'test `cat {} | wc -l` 
-ne N' \; -print


I should have run it through BBEdit's useful "Straighten Quotes" command 
before sending! Sorry for the confusion.

For reference, BBEdit does indeed support the { }-style 
quantifiers as described in the "Quantifiers Repeat Subpatterns" 
in Chapter 8 of the PDF manual (see page 179 in the latest edition).


I regret however that the suggested search pattern of "$\n{min, 
max}" will not do what you're after[*], nor is there any direct 
way to limit a multi-file search to files containing some given 
number of lines.


In order to accomplish that, you'll need to pre-filter the files 
and pass only those of the desired size to BBEdit for searching, 
e.g. in a manner similar to Sam Hathaway's post.


[*: This pattern will instead just match the next run of between 
'min' and 'max' line feeds (i.e. consecutive empty lines) 
following a line break.]

If I am understand your description correctly, something like 
this should work:


-   search for:

^.*?\n{XXX} -- replace the "XXX" with the desired number of lines

-   turn on "Exclude Matches"

-   run your multi-file search.

This will return all files that don't have XXX lines in them.

You can add a file filter to only search "fileinfo.php" files to 
further narrow things down.

Re: Searching files by number of lines in the file

[Sam Hathaway]

Rich’s pattern doesn’t work for me, but this does:

```
\A([^\r]*\r){N}\z
```

Details:

```
   match:
\A  - the beginning of the file
  (){N} - followed by exactly N of:
   [^\r]*  - zero or more non-linebreak characters
 \r- followed by a linebreak
   \z   - followed by the end of the file
```

Note that this assumes that all files end in a linebreak. If they might 
not, you need a slightly more complicated expression:


```
\A([^\r]*\r){M}[^\r]+\Z
```

Where `M` is one _less_ than your target number of lines.

Details:

```
 match:
\A- the beginning of the file
  (){M}   - followed by exactly M of:
   [^\r]*- zero or more non-linebreak characters
 \r  - followed by a linebreak
   [^\r]+ - followed by one or more non-linebreak 
characters
 \Z   - followed by the end of the file OR a 
trailing newline

```

That was fun. Thanks, all. :)

Re: Searching files by number of lines in the file

[Roland Küffner]

Nice problem.
Rich’s patterns works for me - if I put some parentheses around the whole
pattern:

(^.*?\n){XXX}

I guess, without the pattern the quantifier only checks for the „\n“ and
you are in fact searching for a line of text followed by XXX line breaks
(aka empty lines).
