Hi There!
I have the following string
which i need to convert to
i.e. between each occurence of the delimiter ('|' in this case), i need to delete all characters from the '|' to the ':' so that |10,9:12/xxx| becomes |12/xxx|
How can i do this using sed?
Thanks in advance! (13 Replies)
Hi,
I need to delete all text between "|" delimiters. The line in text file typically looks like this:

Line from input file
a : b : c " d " e " f : g : h " i " j " k " l
output

Its taking 7th word when " is the delimiter, 2nd and 1st word when : is the delimiter and returning all in one line.... I am on solaris

I have a file having lines like:
14: <a="b" val="c"/>
18: <a="x" val="d"/>
54: <a="b" val="c"/>
58: <a="x" val="e"/>
I need to create a file with output:
14

54

So basically, for every odd line I need 1st word if delimiter is ':' and for every even... (14 Replies)
Hi all,
I have two (2) sets of files that are based on some snapshots of database that I want to merge and insert any missing sequential number.
Below are example representation of these files:

When cut encounters consecutive delimiters it seems to count each instance as a field, at least with spaces. Is this typical behavior for any delimiter?

Hey guys,
I have a file that is delimited by | and I am trying to write a sed command to
convert this:
abc|def||ghi|jkl||||mnop
into this:
abc|def|-|ghi|jkl|-|-|-|mnop
The output I am getting out of:
sed -e "s/+//g" /tmp/opt.del > /tmp/opt2.del
is like:

sed is not applying /d "delete line" option when I also include match word options \< and \>
examples...
echo cat | sed '/\<cat\>/d'
will return cat for some reason
echo cat | sed "/\<cat\>/d"
will also still return cat.
Of course I can just run this... echo cat | sed '/cat/d' and... (1 Reply)

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.
