I tried using awk as well but that too failed. I read the second file & then started comparing the 5th & 6th column which is the actual requirement for checking.
Code:
while read line
do
BLACK[$counter]=$line
counter = `expr $counter + 1`
done <FILE2

Hi,
I'm trying to validate if a string matches a regular expression, but it is not working. Am I missing something? Do I need to scape any of the characters?
if echo 'en-GB' | egrep '({1,8})(-{1,8})*' >/dev/null; then
echo Valid value

Thanks in advance (6 Replies)

file::counterfile
CounterFile(3pm) User Contributed Perl Documentation CounterFile(3pm)NAME
File::CounterFile - Persistent counter class
SYNOPSIS
use File::CounterFile;
$c = File::CounterFile->new("COUNTER", "aa00");
$id = $c->inc;
open(F, ">F$id");
DESCRIPTION
This module implements a persistent counter class. Each counter is represented by a separate file in the file system. File locking is
applied, so multiple processes can attempt to access a counter simultaneously without risk of counter destruction.
You give the file name as the first parameter to the object constructor ("new"). The file is created if it does not exist.
If the file name does not start with "/" or ".", then it is interpreted as a file relative to $File::CounterFile::DEFAULT_DIR. The default
value for this variable is initialized from the environment variable "TMPDIR", or /usr/tmp if no environment variable is defined. You may
want to assign a different value to this variable before creating counters.
If you pass a second parameter to the constructor, it sets the initial value for a new counter. This parameter only takes effect when the
file is created (i.e. it does not exist before the call).
When you call the "inc()" method, you increment the counter value by one. When you call "dec()", the counter value is decremented. In both
cases the new value is returned. The "dec()" method only works for numerical counters (digits only).
You can peek at the value of the counter (without incrementing it) by using the "value()" method.
The counter can be locked and unlocked with the "lock()" and "unlock()" methods. Incrementing and value retrieval are faster when the
counter is locked, because we do not have to update the counter file all the time. You can query whether the counter is locked with the
"locked()" method.
There is also an operator overloading interface to the File::CounterFile object. This means that you can use the "++" operator for
incrementing and the "--" operator for decrementing the counter, and you can interpolate counters directly into strings.
