awk to print range of fields

Hi

file.in and file.out are in csv format. the code I have now is,
Code:
cat file.in | awk -F"," '!($1$2$3$4$5$6$7$8 in a){a[$1$2$3$4$5$6$7$8];print $0}' > file.out

Here, I am printing entire line using $0. however, I want to print $1 to $150 and it should be in csv format. Cut -d is not good in performace. Using for loop within awk is not producing output as expected.

file.in
Code:
hi,there,how,are,you,123
hi,there,how,are,you,124
hi,there,how,are,you,125
hi,there,how,are,you,126

file.out (please note i have reduced no.of columns for convinience, i need 150 columns)
Code:
hi,there,how,are
hi,there,how,are
hi,there,how,are
hi,there,how,are

Thanks in advance
K

GIT-LS-REMOTE(1)						    Git Manual							  GIT-LS-REMOTE(1)

NAME
git-ls-remote - List references in a remote repository SYNOPSIS
git ls-remote [--heads] [--tags] [--refs] [--upload-pack=<exec>] [-q | --quiet] [--exit-code] [--get-url] [--symref] [<repository> [<refs>...]] DESCRIPTION
Displays references available in a remote repository along with the associated commit IDs. OPTIONS
-h, --heads, -t, --tags Limit to only refs/heads and refs/tags, respectively. These options are not mutually exclusive; when given both, references stored in refs/heads and refs/tags are displayed. --refs Do not show peeled tags or pseudorefs like HEAD in the output. -q, --quiet Do not print remote URL to stderr. --upload-pack=<exec> Specify the full path of git-upload-pack on the remote host. This allows listing references from repositories accessed via SSH and where the SSH daemon does not use the PATH configured by the user. --exit-code Exit with status "2" when no matching refs are found in the remote repository. Usually the command exits with status "0" to indicate it successfully talked with the remote repository, whether it found any matching refs. --get-url Expand the URL of the given remote repository taking into account any "url.<base>.insteadOf" config setting (See git-config(1)) and exit without talking to the remote. --symref In addition to the object pointed by it, show the underlying ref pointed by it when showing a symbolic ref. Currently, upload-pack only shows the symref HEAD, so it will be the only one shown by ls-remote. <repository> The "remote" repository to query. This parameter can be either a URL or the name of a remote (see the GIT URLS and REMOTES sections of git-fetch(1)). <refs>... When unspecified, all references, after filtering done with --heads and --tags, are shown. When <refs>... are specified, only references matching the given patterns are displayed. EXAMPLES
$ git ls-remote --tags ./. d6602ec5194c87b0fc87103ca4d67251c76f233a refs/tags/v0.99 f25a265a342aed6041ab0cc484224d9ca54b6f41 refs/tags/v0.99.1 7ceca275d047c90c0c7d5afb13ab97efdf51bd6e refs/tags/v0.99.3 c5db5456ae3b0873fc659c19fafdde22313cc441 refs/tags/v0.99.2 0918385dbd9656cab0d1d81ba7453d49bbc16250 refs/tags/junio-gpg-pub $ git ls-remote http://www.kernel.org/pub/scm/git/git.git master pu rc 5fe978a5381f1fbad26a80e682ddd2a401966740 refs/heads/master c781a84b5204fb294c9ccc79f8b3baceeb32c061 refs/heads/pu $ git remote add korg http://www.kernel.org/pub/scm/git/git.git $ git ls-remote --tags korg v* d6602ec5194c87b0fc87103ca4d67251c76f233a refs/tags/v0.99 f25a265a342aed6041ab0cc484224d9ca54b6f41 refs/tags/v0.99.1 c5db5456ae3b0873fc659c19fafdde22313cc441 refs/tags/v0.99.2 7ceca275d047c90c0c7d5afb13ab97efdf51bd6e refs/tags/v0.99.3 GIT
