I have a file called test.txt
I have a pattern file called pattern.txt containing the following
I want to do a count, but have it display the count value preceeding each line like grep -n
so
grep -n -f pattern.txt would show
What I would like to do is have grep count the number of occurances in the file and place that value at the begining of the output so it would look like
3 means abc occured 3 times in the file
2 means def occured 2 times in the file
Is there a function or a clever way to achieve this?
I have the following data:
A
1
2
3
A
4
5
6
A
7
8
9
I want to grep this data with A and 3 lines below it then display them in this format:
A 1 2 3
A 4 5 6
A 7 8 9 (4 Replies)

Folks, is it possible to display only words with grep (or any built-in ultility)?
I have more than 1 pattern to search, say apple & orange
The text goes like this:
So I need to display all the words starting with apple or orange
The output should be:
Any idea? (7 Replies)

I use grep to check for a string that validates data in a file, it works great but the problem is that the file is becoming too big and gerp has started hurting the response time to users. Since I only need to find the first occurrence I have been looking for ways to stop grep for scanning the rest... (8 Replies)

I have a file against which I can grep a string for. I can also check for that string count using wc -l (or grep -c). I need to display the results of both in one output i.e. 'line containing string' and 'count' - what would be the most efficient way of managing this? Thanks in advance. (3 Replies)
i have this line of code that looks for the same file if it is currently running and returns the count.
`ps -eaf -o args | grep -i sfs_pcard_load_file.ksh | grep -v grep | wc -l`
basically it is assigned to a variable

pdl::char
Char(3) User Contributed Perl Documentation Char(3)NAME
PDL::Char -- PDL subclass which allows reading and writing of fixed-length character strings as byte PDLs
SYNOPSIS
use PDL;
use PDL::Char;
my $pchar = PDL::Char->new( [['abc', 'def', 'ghi'],['jkl', 'mno', 'pqr']] );
$pchar->setstr(1,0,'foo');
print $pchar; # 'string' bound to "", perl stringify function
# Prints:
# [
# ['abc' 'foo' 'ghi']
# ['jkl' 'mno' 'pqr']
# ]
print $pchar->atstr(2,0);
# Prints:
# ghi
DESCRIPTION
This subclass of PDL allows one to manipulate PDLs of 'byte' type as if they were made of fixed length strings, not just numbers.
This type of behavior is useful when you want to work with charactar grids. The indexing is done on a string level and not a character
level for the 'setstr' and 'atstr' commands.
This module is in particular useful for writing NetCDF files that include character data using the PDL::NetCDF module.
FUNCTIONS
new
Function to create a byte PDL from a string, list of strings, list of list of strings, etc.
# create a new PDL::Char from a perl array of strings
$strpdl = PDL::Char->new( ['abc', 'def', 'ghij'] );
# Convert a PDL of type 'byte' to a PDL::Char
$strpdl1 = PDL::Char->new (sequence (byte, 4, 5)+99);
$pdlchar3d = PDL::Char->new([['abc','def','ghi'],['jkl', 'mno', 'pqr']]);
string
Function to print a character PDL (created by 'char') in a pretty format.
$char = PDL::Char->new( [['abc', 'def', 'ghi'], ['jkl', 'mno', 'pqr']] );
print $char; # 'string' bound to "", perl stringify function
# Prints:
# [
# ['abc' 'def' 'ghi']
# ['jkl' 'mno' 'pqr']
# ]
# 'string' is overloaded to the "" operator, so:
# print $char;
# should have the same effect.
setstr
Function to set one string value in a character PDL. The input position is the position of the string, not a character in the string. The
first dimension is assumed to be the length of the string.
The input string will be null-padded if the string is shorter than the first dimension of the PDL. It will be truncated if it is longer.
$char = PDL::Char->new( [['abc', 'def', 'ghi'], ['jkl', 'mno', 'pqr']] );
$char->setstr(0,1, 'foobar');
print $char; # 'string' bound to "", perl stringify function
# Prints:
# [
# ['abc' 'def' 'ghi']
# ['foo' 'mno' 'pqr']
# ]
$char->setstr(2,1, 'f');
print $char; # 'string' bound to "", perl stringify function
# Prints:
# [
# ['abc' 'def' 'ghi']
# ['foo' 'mno' 'f'] -> note that this 'f' is stored "f "
# ]
atstr
Function to fetch one string value from a PDL::Char type PDL, given a position within the PDL. The input position of the string, not a
character in the string. The length of the input string is the implied first dimension.
$char = PDL::Char->new( [['abc', 'def', 'ghi'], ['jkl', 'mno', 'pqr']] );
print $char->atstr(0,1);
# Prints:
# jkl
