I have 2 files with a common parm - Jobname

File 1
0507 1202 JOBA
0507 1302 JOBB
0507 1452 JOBC
0507 1552 JOBA
0507 1553 JOBA

File2

JOBA abcdefg server4
JOBB defghij server22
JOBC vwxyz12 server55

I would like to take each line from File1 and match the jobname with the jobname in File 2 and produce File 3 as

0507 1202 JOBA abcdefg server4
0507 1302 JOBB defghij server22
0507 1452 JOBC vwxyz12 server55
0507 1552 JOBA abcdefg server4
0507 1553 JOBA abcdefg server4

Could anyone help please, I'm new to scripting.

nawk 'NR == FNR{rec[$1] = $2" " $3; next}

{ print $0 " " rec[$3]}

' 64491_merge1.d 64491_merge.d

0507 1202 JOBA abcdefg server4
0507 1302 JOBB defghij server22
0507 1452 JOBC vwxyz12 server55
0507 1552 JOBA abcdefg server4
0507 1553 JOBA abcdefg server4

Brilliant Thanks very much indeed!

Another one:
(use nawk or /usr/xpg4/bin/awk on Solaris)

awk 'NR==FNR{x[$1]=$0;next}$NF=x[$NF]' file2 file1

Having tested this on the simple files I provided it appears it doesn't work on the more complexed files. The first file has 6 field separated by blanks

File1

LVTS4687 LVTSHPLON ltreb_shu1l110 LVTS4687 LVTSHPLON shu1l110
LVTS1457 LVTSHP sy_unix_live_rooma_onsite_35_35 LVTS1457 LVTSHP syhp10

LVTS4021 LVTSHP nw_unix_live_phase4_duplex_35_90 LVTS4021 LVTSHP nhu1u282

The second file has 5 fields
File 2
0508 0601 LVTS4687 58 1
0509 0108 LVTS4687 58 1
0509 0108 LVTS4687 58 1
0509 0108 LVTS4687 58 1
0508 2206 LVTS5035 98 1
0508 2206 LVTS5035 98 1
0508 2206 LVTS5035 98 1
0508 2206 LVTS5430 98 1
0508 2206 LVTS5430 98 1
0508 2206 LVTS5430 98 1
0508 2206 LVTS5431 98 1
0508 2206 LVTS5431 98 1
0508 2206 LVTS5431 98 1
0506 0920 LVTS5750 141 3

0506 0920 LVTS5750 141 3
0506 0920 LVTS5750 141 3
0506 0920 LVTS5750 141 3
0506 0920 LVTS5750 141 3


and the result would need to look like

this file comprises of field 1 2 3 4 5 of file2 and field 3 and 6 of file1

It seems quite easy, did you try to adapt the code yourself?

awk 'NR==FNR{_[$1]=$3 FS $6;next}$NF=$NF _[$3]' file1 file2>file3
