I'm looking for what I hope might be a one liner along these lines:
I know how to get the pipe count in a string and store it in a variable, but I'm greedy enough to hope that it's possible via regex in the /.../d context. Am I asking too much? Thanks in advance!

For counting the occurences of specific character in the file
I am issuing the command
grep -o 'character' filename | wc -w
It works in other shells but not in HP-UX as there is no option -o for grep.
What do I do now? (9 Replies)
I'm trying to count the number of 2 specific characters in a very large file. I'd like to avoid using gsub because its taking too long.
I was thinking something like:
awk '-F' { t += NF - 1 } END {print t}' infile > outfile
which isn't working
Any ideas would be great. (3 Replies)
Hi,
I wanted to add a newline character after every 100 characters in a file using a awk or shell without reading each line of the file.

Hi,
I need add leading zeroes to a field in a file based on the character count. The field can be of 1 character to 6 character length. I need to make the field 14bytes.
eg:
8351,20,1
8351,234,6
8351,2,0
8351,1234,2
8351,123456,1
8351,12345,2
This should become.

Hi,
I need help regarding counting specific word or character per line and validate it against a specific number i.e 10. And if number of character equals the specific number then that line will be part of the output.

Hello,
:wall:
I have a 12 column csv file. I wish to delete the entire line if column 7 = hello and column 12 = goodbye. I have tried everything that I can find in all of my ref books.
I know this does not work

Any ideas?
Thanks

devel::refcount
Devel::Refcount(3pm) User Contributed Perl Documentation Devel::Refcount(3pm)NAME
"Devel::Refcount" - obtain the REFCNT value of a referent
SYNOPSIS
use Devel::Refcount qw( refcount );
my $anon = [];
print "Anon ARRAY $anon has " . refcount($anon) . " reference
";
my $otherref = $anon;
print "Anon ARRAY $anon now has " . refcount($anon) . " references
";
DESCRIPTION
This module provides a single function which obtains the reference count of the object being pointed to by the passed reference value.
FUNCTIONS
$count = refcount($ref)
Returns the reference count of the object being pointed to by $ref.
COMPARISON WITH SvREFCNT
This function differs from "Devel::Peek::SvREFCNT" in that SvREFCNT() gives the reference count of the SV object itself that it is passed,
whereas refcount() gives the count of the object being pointed to. This allows it to give the count of any referent (i.e. ARRAY, HASH,
CODE, GLOB and Regexp types) as well.
Consider the following example program:
use Devel::Peek qw( SvREFCNT );
use Devel::Refcount qw( refcount );
sub printcount
{
my $name = shift;
printf "%30s has SvREFCNT=%d, refcount=%d
",
$name, SvREFCNT($_[0]), refcount($_[0]);
}
my $var = [];
printcount 'Initially, $var', $var;
my $othervar = $var;
printcount 'Before CODE ref, $var', $var;
printcount '$othervar', $othervar;
my $code = sub { undef $var };
printcount 'After CODE ref, $var', $var;
printcount '$othervar', $othervar;
This produces the output
Initially, $var has SvREFCNT=1, refcount=1
Before CODE ref, $var has SvREFCNT=1, refcount=2
$othervar has SvREFCNT=1, refcount=2
After CODE ref, $var has SvREFCNT=2, refcount=2
$othervar has SvREFCNT=1, refcount=2
Here, we see that SvREFCNT() counts the number of references to the SV object passed in as the scalar value - the $var or $othervar
respectively, whereas refcount() counts the number of reference values that point to the referent object - the anonymous ARRAY in this
case.
Before the CODE reference is constructed, both $var and $othervar have SvREFCNT() of 1, as they exist only in the current lexical pad. The
anonymous ARRAY has a refcount() of 2, because both $var and $othervar store a reference to it.
After the CODE reference is constructed, the $var variable now has an SvREFCNT() of 2, because it also appears in the lexical pad for the
new anonymous CODE block.
PURE-PERL FALLBACK
An XS implementation of this function is provided, and is used by default. If the XS library cannot be loaded, a fallback implementation in
pure perl using the "B" module is used instead. This will behave identically, but is much slower.
