Multithreaded Alternative to grep

grep which is the most popular tool used to make regex searches on Linux systems, has been around for a while. The current implementation of grep is single-threaded and does not make use of modern multi-core systems. This is specially evident when the search is spread over a large number of files and directories. Thus, we plan to implement an improved version of grep which makes use of modern concurrency and parallelism.

clone the repository:

git clone "https://github.com/IITH-SBJoshi/concurrency-7.git"

create directory for build

  cd Grape 
  mkdir build && cd build

build the project

  cmake .. && make 

sudo required to execute from any position.

  sudo cp ./grape /bin/

grape [OPTION]... PATTERN [FILE]
Search for PATTERN in each FILE.
Example: grape -i 'hello world' main.c

Pattern selection and interpretation:
 -F,   --fixed-string         {default}PATTERN is a normal string
 -G,   --basic-regexp         PATTERN is a basic regular expression (default)
 -e,   --regexp=PATTERN       use PATTERN for matching
 -i,   --ignore-case          ignore case distinctions

Miscellaneous:
       --version              display version information and exit
       --help                 display this help text and exit
       --usage                display usage text and exit

Output control:
 -n,   --line-number          print line number with output lines
 -r,   --recursive            recursive search inside directory
 -L,   --files-without-match  print only names of FILEs with no selected lines
 -l,   --files-with-matches   print only names of FILEs with selected lines

note:-  gtest is required for normal cmake install .
  if you don't want to install gtest then remove CmakeList.txt 
  and rename _CMakeLists.txt as CMakeLists.txt .
