unix - awk script not working properly in SunOS (which worked well with Red Hat) -

i looking out file replacement functionality done in awk. had solution worked red hat linux flavour not working sunos 5.10. great if can troubleshoot issue.

source file (src.txt)

aaaa uid=xxxx pwd=nnnn u_no=12345 bbbb uid=yyyy pwd=eeee zzzz uid=yyyy pwd=eeee 

reference file (ref.txt)

block,parameter,value aaaa,uid,1a1a aaaa,pwd,1b1b bbbb,uid,2a2a zzzz,pwd,9b9b zzzz,uid,9a9a bbbb,pwd,2b2b 

required output file (tgt.txt)

the target file should updated source file based on lookup values reference file follows:

aaaa uid=1a1a pwd=1b1b u_no=12345 bbbb uid=2a2a pwd=2b2b zzzz uid=9a9a pwd=9b9b 

code

awk -f= ' fnr==nr { split($0,b,",") a[b[1] fs b[2]]=b[3] next}  !/=/ { f=$1 print next}  { print $1"="(a[f fs $1]?a[f fs $1]:$2)} ' ref.txt src.txt > tgt.txt 

the code solution given 1 of our friends here in stack overflow , worked pretty in red hat linux.

when tried copy sunos 5.10, first showed syntax error at:

!/=/ {    

i replaced field separator value , stopped showing syntax error.

ofs="=" 

for this, script executes, prints source file values (not updated value).

can me find solution this?

use nawk (new awk) or /usr/xpg4/bin/awk (posix awk) solaris. awk original legacy version.

here works:

nawk -f= ' fnr==nr { split($0,b,",") a[b[1] fs b[2]]=b[3] next} $0 !~ "=" { f=$1 print next} { print $1"="(a[f fs $1]?a[f fs $1]:$2)} ' ref.txt src.txt > tgt1.txt
