Hi graff,
Here i am explaining in detail what actually i am trying to extract.
I am working on a task to get the vob storage path from the list of vobtags.below is the command i am running on command prompt
bash-3.00$cleartool lsvob -s #which will give all vobtag list as below.
/vobs/cs_test_scripts
/vobs/openwall_pam_userpass_rel
/vobs/cs_cim
/vobs/PIP_PVOB
/vobs/pvob_ic
/v_dialer3rdparty
/v_dialerclient
/v_dialer_rel
/scm

[download]
#!/usr/bin/perl -w
$arg=$ARGV[0];
$cmd="cleartool lsvob $arg"
$arr=`$cmd`;
print "$arr\n";

[download]
after running this script with argument as vobtag list that i got from running "cleartool lsvob -s" command
like as bash-3.0$cleartool lsvob /vobs/cs_test_scripts from command prompt will give the result as below 
* /vobs/cs_test_scripts /usr/add-on/puccase_vob01/ccvob01/cs_test_scri
+pts.vbs public (replicated)
* /scm /usr/add-on/puccase_vob01/ccvob01/scm.test.vbs

[download]
the output contains three parts */vobs/cs_test_script,*/scm are as vobtags
/usr/add-on/puccase_vob01/ccvob01/cs_test_scripts.vbs is vobstorage directory path
and last part is type as "public (replicated)".
from this i want to extract vobstorage path of each vobtag that i am supling vobtag(/vobs/cs_test_script)as argument to the below script,in that i am matching the output for the tags with 2 slashes in it ex:/vobs/cs_test_script and
vobtag with one slash in it ex:/scm
with regular expression that has to match the output for both type of vobtags(/vobs/cs_test_script,/scm)by using alternation operator in patternmatching as below script
#!/usr/bin/perl
$arg=$ARGV[0];
$cmd1="cleartool lsvob  $arg";
$arr=`$cmd1`;
print "$arr\n";
$storage1=$1 if($arr=~/^*\s+\/\w+\/\w+\s+(.+)\s+\w+/);
print "$storage1\n";
$storage2=$1 if($arr=~/^*\s+\/\w+\s+(.+)\s+\w+/);
print "$storage2\n";
$storage3=$1 if($arr=~/^*\s+\/\w+\/\w+\s+(.+)\s+\w+|^*\s+\/\w+\s+(.+)\
+s+\w+/);
print "$storage3\n";

I am running the script with both type of vobtags as /vobs/cs_test_scripts and /scm as arguments so its printing the match for both $storage1 and $storage2 as below
bash-3.00$ perl scriptname.pl /vobs/cs_test_script
bash-3.00$ perl scriptname.pl /scm 
* /vobs/cs_test_scripts /usr/add-on/puccase_vob01/ccvob01/cs_test_scri
+pts.vbs public (replicated)
#match storage1 /usr/add-on/puccase_vob01/ccvob01/cs_test_scripts.vbs
* /scm                 /usr/add-on/puccase_vob01/ccvob01/scm.vbs publi
+c (replicated)

#storage2 /usr/add-on/puccase_vob01/ccvob01/scm.vbs

In $storage3 variable i am combining the pattern match of storage1 and storage2 by alternation operator,it should work for both type of vobtag arguments,i am not getting where i am doing wrong...
Monks sorry for repeated posting of same qustion again and again...the problems seems to simple for u people ....
