perl one-liner?

[haiwu.us]

I have one ldif file, which is a dump file from Oracle OID. Many lines
got cut into 2 lines due to 80 columns limit, not sure why. So there
are many similar lines as follows in the file (there will always be an
empty space char in the beginning of the 2nd line):

cn: ias_admin
creatorsname:
orclapplicationcommonname=uddi,cn=portal,cn=products,cn=oracleco
ntext
modifiersname:
orclapplicationcommonname=uddi,cn=portal,cn=products,cn=oraclec
ontext
description: UDDI Registry Administrator. It maps to the ias_admin user
of Ent
erprise Manager.

I want to change the above to below:
cn: ias_admin
creatorsname:
orclapplicationcommonname=uddi,cn=portal,cn=products,cn=oraclecontext
modifiersname:
orclapplicationcommonname=uddi,cn=portal,cn=products,cn=oraclecontext
description: UDDI Registry Administrator. It maps to the ias_admin user
of Enterprise Manager.

Is it possible for perl one-liner?

Is it possible for perl one-liner?

One can (possibly/probably) write ten thousand 'lines' of Perl in one
line (with 9_999 semi-colons). Just out of curiosity, why do you care
what the line count is?

Is it possible for perl one-liner?

I don't know about a one-liner. Here is the standard way of dealing
with continuation lines:

my $buf;
while ( <DATA> ) {
chomp;
if ( s/^ // ) {
$buf .= $_;
} else {
print "$buf\n" if $buf;
$buf = $_;
}
}
print "$buf\n" if $buf;

perl -ln0e '$m=$1,($n=$2)=~s/\s*\n\s*//g and print "$m: $n"
while/^([^:]*):\s*([^:]*)(?=^[^:]*:|$)/mg' file.txt

this may roughly do it, except that in the fourth line, "user of" is
changed to "userof".. I dont know why you left spaces between "Ent" and
"erprise", if I chomped these whitespaces, I also chomped the
whitespaces between normal texts like "user" and "of". so what's your
rule to distinguish between these two??..

This can be done using one line sed command. I am thinking perl would
probably do a better job than sed in this case.

This is the simplest one-liner that I saw so far.

Thanks,

it depends on your data format? I am guessing the data you posted in
the group are not as your original format or I didn't understand your
requirements correctly. basically, perl can do most of the oneliners as
sed does...

I mean this one: perl -lpe'BEGIN{$/="\n ";$\=""}' yourfile

This is a file created in Linux using Oracle OID ldifwrite. I don't
know why it split output lines longer than 80 chars into 2 lines, with
the 2nd line having one empty space char in its beginning.

That line should look like this: (I am omitting the beginning since I
am afraid this HTML form will also wrap the line)
UDDI Registry Administrator. It maps to the ias_admin user of Ent
erprise Manager.

It should be changed to:
UDDI Registry Administrator. It maps to the ias_admin user of
Enterprise Manager.

Playing fast and loose with newlines:

perl -ne 'print("\n"), chomp, print, next unless s/^ //; chomp, print' file


Getting the newlines right makes it rather unwieldly for a one-liner:

perl -ne 'print($.==1 ? "" : "\n"), chomp, print, next unless s/^ //; chomp, print; END{print"\n"}' file


I think I'd write a dozen lines of clear code instead.
