Need 'grep' equivalent

[old4doser]

Yes, I have looked (in vain) for this in Help. I have the calluses to prove it. I’ve also searched most of the Internet 4DOS-related websites with no success.

What is the TC version of the UNIX “grep”. Right now I’m using the ‘The Berkeley Utilities V2.0’ ‘grep’ like this to test for a string in a file

type "%theMonFile%" |grep -s markit
set exitcode=%_?

That works fine, but there has to be an equivalent way to do it with TC commands, but I cannot find out how to do it.

A more basic use of ‘grep’ is to find all lines in a text file that contain a certain string. I’d like to know how to do that too.

Normally, I’d be happy with just knowing what is used to get these two file searches done like ‘grep’. But given the scant nature of the examples in Help, a few examples would be appreciated.

Or, let me know what to search for and I can try to find something in the forums.

Thanks

If you don't need wildcards and all the other bells and whistles that a real grep gives you, the good old 'find' command (from cmd.exe) might be the answer:

C:\
which find
find is an external : C:\Windows\system32\find.exe

C:\
cmd /k help find
Searches for a text string in a file or files.

FIND [/V] [/C] [/N] [/I] [/OFF[LINE]] "string" [[drive:][path]filename[ ...]]

  /V         Displays all lines NOT containing the specified string.
  /C         Displays only the count of lines containing the string.
  /N         Displays line numbers with the displayed lines.
  /I         Ignores the case of characters when searching for the string.
  /OFF[LINE] Do not skip files with offline attribute set.
  "string"   Specifies the text string to find.
  [drive:][path]filename
             Specifies a file or files to search.

If a path is not specified, FIND searches the text typed at the prompt
or piped from another command.

Did you try the internal FFIND command? It should be usable via pipes and such as well according to the help.

"If you don't supply a file name, FFIND will read from standard input. (This allows you to pipe or redirect input to FFIND.)"

list allows regular expressions. Is this what you want, or are you=20
looking for something like the linux find command?

The internal TCC "FFIND" command searches files (text, binary, or regular
expressions).

FFIND /v /t"string" filename

The LIST command can also search files if you'd rather have a visual
display.

4DOS has the FFIND command, which is also in TCC.

I am not familiar with the Berkeley version of grep, so I don't know
what the return code means. Here are some variant uses of the TCC version
11.0 command FFIND.
- List of files that have at least one match to a plain text string:
ffind /b /t"string" fileset
- List of files that have at least one match to a regular expression:
ffind /b /e"regex" fileset

Look up the /c, /l and /v options of FFIND. The only thing FFIND cannot
do is what some versions of grep provide, namely, to provide a single line
report containing filename, linenumber, and matching line for each match.
BTW, FFIND's output can be fed through a pipe to any other command (or
batchfile or even external program) providing an emulation of the POSIX
command "find".

There's Windows's TCC's FFIND and FINDSTR.EXE, neither of which do
full-blown regular expressions. My 4UTILS plugin provides a GREPP
command.

 

[samintz]

FFIND does do regular expressions with the /E switch. Which part is
missing? I.e. what can't you do?

For some advanced searching, you may want to look into;

@REGEX
@REGEXINDEX
@REGEXSUB

Mind you, this may be more that what you require.

My thanks for all of the responses to my question about a TC equivalent to
the UNIX "grep" command. The responses were enlightening and revealing. The
suggestions included the TC "ffind" and "filefind", Windows "find" and
"findstr", plus a plugin and a lot of talk about Regular Expressions.



In the end, the answer is NO. To me it's unconscionable that there wouldn't
be one, but that seems to be the case. I'm an old UNIX guy, and what grep
does is what I want the way grep does it. Just give me an exit-code and a
list of "result" lines to stdout.



The solutions to both of my "grep" needs is the Windows "find". One uses the
/c (count) switch and the other is bare. My searches are only on ASCII/text
files without any Regex.



1. Is this string in the file?



for /f "tokens=2 delims=:" %%a in ('find /c "%string%" "%filename"') do set
fstr=%%a



The variable "fstr" has the count (or 0) with a leading space. In that form,
the variable can be used in an "if" of "iff" to test it.



2. Get all lines with this string in them.



find "%string%" "%filename"



There are also /V and /I for "get all without the string" and
"case-insensitive", both basic in the UNIX "grep".



Again, my thanks. I included my findings in hopes of contributing something
back for all your time and efforts.



George

You may find that the internal FFIND command has a lot more power to do
what you ask than you are giving it credit for.

[C:\Tools\Crypto32] ffind /u /v /t"Crypt" *.cpp
75 lines in 1 file

[C:\Tools\Crypto32] ffind /u /v /t"foo" *.cpp
0 lines in 0 files

set fstr=%@word[0,%@execstr[ffind /u /v /t"%string" %filename]]

or

function matches=`%@word[0,%@execstr[ffind /u /v /t"%1" %2]]`
echo %@matches[Crypt,*.cpp]
echo %@matches[`Certificate failed`,*.cpp]

Remove the /U switch to get the equivilent of your #2.

1) find all occurances of %string within %filename case insensitive
ffind /v /t"%string" %filename

2) find all occurances of %string within %filename case sensitive
ffind /v /c /t"%string" %filename

You may find that the internal FFIND command has a lot more power to do what you ask than you are giving it credit for.

There are also plenty of Windows ports of grep. I've been using GNU grep 2.5.1: ftp://ftp.fh-hannover.de/pandora/files/linux/UnxUpdates.zip

 

[old4doser]

It turns out that ffind will do everything I want a virtual-grep to do. I
passed it over before because the format of its "count" output was more
complex than that of Windows' "find", and "find" had a straightforward
"results" output. Also, I got "find" to work in a short time, while ffind
was a 'file-find' command by definition and I didn't want to spend hours
struggling with the options and post-processing to get what I had from
"find".

But, Scott (aka samintz) showed me how to get the "exitcode" (count) and
"results" lines from ffind. In doing that, he provided examples of
"function", @word and @execstr showing me how they work in a context that I
was familiar with.

Thanks Scott.
