Your example is incomplete and a little vague. If I've guessed correctly at what you want, the awk script below may do what you want:

Code:

awk '
/^HLD_EA/ {
        if(out) print out
        out = $0
        next
}
{       out = out "\t" $0
}
END {   if(out) print out
}' file

As always, if you're using a Solaris/SunOS system, use /usr/xpg4/bin/awk, /usr/xpg6/bin/awk, or nawk instead of awk.

With your sample input file, the output produced is:

Code:

HLD_EA_0001X	HLD_DOORS_002X
HLD_EA_0002X	HLD_DOORS_003X	HLD_DOORS_0033
HLD_EA_0003X	HLD_DOORS_004X	HLD_DOORS_0032
HLD_EA_0004X	HLD_DOORS_005X	HLD_DOORS_0031
HLD_EA_0005X	HLD_DOORS_006X	HLD_DOORS_0029	HLD_DOORS_0030
HLD_EA_0006X	HLD_DOORS_007X	HLD_DOORS_0027
HLD_EA_0007X

awk - Matching columns between 2 files and reordering results

I am trying to match 4 colums (first_name,last_name,dob,ssn) between 2 files and when there is an exact match I need to write out these matches to a new file with a combination of fields from file1 and file2.

ucblinks

ucblinks(1B)					     SunOS/BSD Compatibility Package Commands					      ucblinks(1B)

NAME

       ucblinks - adds /dev entries to give SunOS 4.x compatible names to SunOS 5.x devices

SYNOPSIS

       /usr/ucb/ucblinks [-e rulebase] [-r rootdir]

DESCRIPTION

       ucblinks  creates symbolic links under the /dev directory for devices whose SunOS 5.x names differ from their SunOS 4.x names. Where possi-
       ble, these symbolic links point to the device's SunOS 5.x name rather than to the actual /devices entry.

       ucblinks does not remove unneeded compatibility links; these must be removed by hand.

       ucblinks should be called each time the system is reconfiguration-booted, after any new SunOS 5.x links that are needed have been  created,
       since the reconfiguration may have resulted in more compatibility names being needed.

       In  releases prior to SunOS 5.4, ucblinks used a  nawk rule-base to construct the SunOS 4.x compatible names. ucblinks no longer uses  nawk
       for the default operation, although  nawk rule-bases can still be specifed with the -e option.  The  nawk rule-base equivalent to the SunOS
       5.4 default operation can be found in /usr/ucblib/ucblinks.awk.

OPTIONS

       -e rulebase     Specify rulebase as the file containing nawk(1) pattern-action statements.

       -r rootdir      Specify rootdir as the directory under which dev and devices will be found, rather than the standard root directory /.

FILES

       /usr/ucblib/ucblinks.awk        sample rule-base for compatibility links
