unix help

1.
i am trying to build a command that searches a text file
and outputs the number of words which consists of two 'b' characters
in each word separatly

like
barby

(the b characters must be separated from one another)
i tried to use grep [b][b] filepath
then i know that we need to use pipe to count the result

but it prints all the word with the two b chars
one next to the other

how do i build this command
2.
i am trying to build a command that searches a text file
and outputs the number words which consists of two 'x' characters
only
i tried to use

man wc

now i can count them but i cant figure out
how to filter out the undesirable words

I don't know of a command, but you can do this with a perl script.

*dusting off perl skills*

...

*dusting failed. using can of compressed air*

Code:

---

#!/usr/bin/perl
$file = "testing.txt";

open (CRAP,$file) || die "Can't open file '$file'. Reason: $!\n";
@garbage = <CRAP>;
close CRAP;

foreach $i (@garbage){
 @words = split(/ /,$i);
 foreach $w (@words){
 chomp($w);
  # Uncomment one of the lines below for desired effect,
  # but make sure to comment out the one you don't want:

  # v Matches only letters between 2 b's. Uncommented as default.
  if ($w =~ /b[a-zA-Z]+b/i){

  # v Matches any alphanumeric characters between 2 b's
  #    (including numbers and _) ie, b1g_a55_b00ty
  # if ($w =~ /b\w+b/i){
      $count++;
      push (@results, $w);
    }
  }
 }

if ($count<1){
print "No results found.\n";

}else{

print "Found $count matches. Writing results to file 'results.txt' in this directory. \n";

# This will overwrite results.txt if it already
# exists. To simply append new results to the
# existing file, change >results.txt to >>results.txt
open (RES, ">results.txt") || die "Cannot open results.txt for writing. Reason: $!\n";
foreach (@results){
print RES $_;
print RES "\n";
}
close RES;
}

Tested with a NYTimes article about baseball so I was able to debug a bit so the results file looks nice and clean.

So, what did I do all this for? Why do you need to find 2 b's spaced apart? Just curious...

Also, this will work for x's as well. Just change /b[a-zA-Z]+b/i to /x[a-zA-Z]+x/i

If they need to be together and not seperate the you need to take out everything between the letters, ie: /xx/i

The i means case-insensitve, so if you only want to look for XX or xx or Xx and not xX then take the i off.

i need it as a command

Oh, well excUUUUUUUUUUUse me sir,

if ur running unix you can edit the script with filenames and run it at the command line. or you can rewrite it to accept filenames as args and use it as a command, not that hard. or you can just keep checking back and seeing if anyone has posted ur golden command.

Where the hell did I put the Neg-0-Matic 2000?

Nice script x, I do have one question however, why did you write it? Really?

@ xiphias360:

1. Go to your hardware store and buy a sledge hammer
2. Preferably, but you need to be older than you sound: get a 9mm automatic weapon.
3. Issue the command: "run this you feckin booger or die" Remember to raise the hammer/point the weapon before entering the command.

Points to remember........... no matter what sort of OS or hardware you run,

They DO NOT understand:

1. Semtex
2. C4/PE4
3. Thermite
4. Industrial strength corrosives

So command lines including those statements won't work :cool:

cuz i knew it could be done quick & easy with perl, and to help this ungrateful tard. well no more mr. nice X...

and what's a Neg-o-matic supposed to be? neg rep??

OMG! It's neg rep! everybody RUUUUUUUUUUN!!!!!!!!!!!!!

board points don't pay my car note, so im probably not gonna cry if i loose them, lol...

Nice script x

I don't think that you were the target dinowuff had in mind?:D

Sorry x I didn't word my post clearly enough. What I meant to say was If I could find my Neg-0-Matic 2000 (A virtual device, left over from the Antionline anti-point days, that when fired would instantly BANN ungrateful little turds) I would point and fire at newby.

Oh, well im all types of retarded, lol...

thanks for the posts but

i didnt want to offend you

i just sayd that i cant use it

i tried to look for a tool in google for switching perl code into
unix command .
i didt find anything
any way thanks for the help

take it easy

?? is he serious? lol...

I think so, but I have come to the conclusion that English is not his first, and probably not even his second language?

He appears to be trying to learn the Unix command language, and, when he says he wants a "command" he actually means that he wants a "command language program" (CLP), or "script".

Obviously, you are not going to find anything to convert perl scripts into UCL. If I recall my Unix lessons (many, many, years ago:eek:), Perl was originally designed for the Unix platform and was noted for its handling of text manipulation?

That would make it an excellent choice for the apparent task, as you so ably demonstrated.

In his original post he says:

but it prints all the word with the two b chars
one next to the other

So why not just write that output to a temporary file, count the number of words and output the result, then delete the temporary file?

As you may have gathered, I never was one for "elegant solutions" :D
