Full Discussion: Accepting a phrase and counting the number of times that it is repeated in a specific website
Homework and Emergencies Homework & Coursework Questions Accepting a phrase and counting the number of times that it is repeated in a specific website Post 302879409 by bakunin on Thursday 12th of December 2013 10:07:33 AM

I am not sure if this is within the scope of your homework, but will probably have to escape several characters to make your regexp more robust.

Here is an example you can try to see the problem:

Code:
This is the inputfile.
This is a line
A line not containing the word "i s".

Code:
# search="is"
# grep -c "$search" /path/to/inputfile
2

So far, so good. Let us search for full stops. There are 2 lines with a full stop (1 and 3):

Code:
# search="."
# grep -c "$search" /path/to/inputfile
3

Obviously wrong, no? Contemplate the reason why and find out how to correct that.

I hope this helps.

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
