Removing spaces between parenthesis ()
Hello,

i 've go a file with the following text:

Code:
oracle@das (J005)                                              0
oracle@das (J008)                                              0
oracle@das (J050)                                              0
oracle@das (J038)                                              0
oracle@das (J105)                                              0
oracle@das (J058)                                              0
oracle@das (J088)                                              0
oracle@das (J090)                                              0
oracle@das (J032)                                              1
oracle@das (J113)                                              0
oracle@das (J121)                                              0
httpd@MANAGED-UAS1 (TNS V1-V3)                                 0
oracle@das (J002)                                              0

I tried numerous ways with sed to remove only any space which happen to be in the parenthesis only ().
Such that:
Code:
httpd@MANAGED-UAS1 (TNS V1-V3)

Will have:
Code:
httpd@MANAGED-UAS1 (TNSV1-V3)

i've tried:
Code:
cat test.txt | sed -e 's/([(^)]*)//g'
 perl -p 's{(\( .*? \))}{$1 =~ y/ //dr}gex'
 sed -e 's/([(^)]*)( )/\1/'

But none seems to work. Any thoughts or hints?

Rgds,

linux::distribution

Linux::Distribution(3pm)				User Contributed Perl Documentation				  Linux::Distribution(3pm)

NAME

       Linux::Distribution - Perl extension to detect on which Linux distribution we are running.

SYNOPSIS

	 use Linux::Distribution qw(distribution_name distribution_version);

	 if(my $distro = distribution_name) {
	       my $version = distribution_version();
	       print "you are running $distro, version $version
";
	 } else {
	       print "distribution unknown
";
	 }

	 Or else do it OO:

	 use Linux::Distribution qw(distribution_name distribution_version);

	 my $linux = Linux::Distribution->new;
	 if(my $distro = $linux->distribution_name()) {
	       my $version = $linux->distribution_version();
	       print "you are running $distro, version $version
";
	 } else {
	       print "distribution unknown
";
	 }

DESCRIPTION

       This is a simple module that tries to guess on what linux distribution we are running by looking for release's files in /etc.  It now looks
       for 'lsb-release' first as that should be the most correct and adds ubuntu support.  Secondly, it will look for the distro specific files.

       It currently recognizes slackware, debian, suse, fedora, redhat, turbolinux, yellowdog, knoppix, mandrake, conectiva, immunix, tinysofa,
       va-linux, trustix, adamantix, yoper, arch-linux, libranet, gentoo, ubuntu, scientific, oracle enterprise linux and redflag.

       It has function to get the version for debian, suse, fedora, redhat, gentoo, slackware, scientific, oracle enterprise linux, redflag and
       ubuntu(lsb). People running unsupported distro's are greatly encouraged to submit patches :-)

   EXPORT
       None by default.

TODO

       Add the capability of recognize the version of the distribution for all recognized distributions.
