Question
Project #6 Perl
This assignment has two parts. Each part must be done using Perl.
Part A – find.pl
Create the script find.pl which searches for files in a directory list based on a regular expression pattern:
If the file name matches, print that file name.
If the file name doesn't match, it should look for instances of the regular expression within the text of the file. If found, it should print the filename, a colon, and the text for the first line that contained that pattern.
If the -i option is passed, the script should return the opposite files (i.e., those which do not match the expression in file name or contents). The script should be invoked with the following format:
find.pl -i perlRegexpPattern listOfFiles
where -i is optional.
Example data is located in /usr/local/courses/clark/cs3423/2017Fa/Proj6/
For part A, copy those into a directory named "DataA".
Example: For a directory, DataA, containing the following files:
input.txt proj1.c proj1.o proj12.c projPerl1.pl
projPerl1.input projZ.c projZ.h trash.txt
Assuming input.txt contains the following text:
Hello World
This is input for proj1
Test data
find.pl should behave in the following way (the order of the files is insignificant):
$ find.pl ".*proj1.*" DataA/*
input.txt:This is input for proj1
proj1.c
proj1.o
proj12.c
$ find.pl -i ".*proj1.*" DataA/*
projPerl1.pl
projPerl1.input
projZ.c
projZ.h
trash.txt
Explanation / Answer
Code for projectSorter.pl :
#!/usr/bin/env perl
use strict;
use warnings;
use File::Copy;
#Variable declaration done one for source variable reading from script parameter and other for misc folder
my $source_dir = $ARGV[0];
my $target_dir = "/misc";
#Now by using grep condition get thet both file names list (one to misc other depending on file name)
my @files_Name_proj = grep ( -f ,<proj*>) read_dir $source_dir;
my @files_Name_Not_proj = grep ( -f ,<-v proj*>) read_dir $source_dir ;
#Move all files to misc folder for files not starting with proj.
foreach my $t (@files_Name_Not_proj)
{
if(! -f "$source_dir/$t" ) {
#Check with -f only for files (no directories)
copy "$source_dir/$t", "$target_dir/$t";
}
}
#Create new directory and move files starting with proj according to the filename projXXX
foreach my $t (@files_Name_proj)
{
if(! -f "$source_dir/$t" ) {
my $Assignment_Index = split 'proj', $t;
#Check with -f only for files (no directories)
copy "$source_dir/$t", /assignment."$Assignment_Index";
}
}
