Does your OS provide other sed versions?



For debugging, try to restrict yourself to match the months only. You may want to apply vgersh99's proposal as well to get rid of the {2}.

RudiC:

Thanks for suggestion, I tried. It output the same result. I know the Date format in our SQL script is not configured well. But I cannot make change at this time. It will cause many changes. On our Solaris 10, we have /usr/xpg4/bib/sed, can this sed work?
These two use vgersh99's proposal and without {2}
Code:
/home/oracle> sed -e "s/[0-3][0-9]-($(locale abmon | tr 'a-z;' 'A-Z|'))-[12][09][0-9][0-9]/$NEWDATE/" test4.txt
       ep.begin_date, ep.end_date, ep.facility_code,
AND    ep.begin_date <= '01-JUL-2019'
       ep.begin_date, ep.end_date, ep.facility_code,
AND    ep.begin_date <= '01-JUL-2019'
       ep.begin_date, ep.end_date, ep.facility_code,
AND    ep.begin_date <= '01-JUL-2019'

/home/oracle> sed  "s/[0-3][0-9]\-[a-zA-Z]{3}\-[12][09][0-9][0-9]/$NEWDATE/" test4.txt
       ep.begin_date, ep.end_date, ep.facility_code,
AND    ep.begin_date <= '01-JUL-2019'
       ep.begin_date, ep.end_date, ep.facility_code,
AND    ep.begin_date <= '01-JUL-2019'
       ep.begin_date, ep.end_date, ep.facility_code,
AND    ep.begin_date <= '01-JUL-2019'

I am working on how to restrict to match the month. Thanks for your help.

You'll have to debug stepwise. What be the result of

Code:
sed  "s/\(JUN\|JUL\|AUG\)/XXXX/" file

?
And yes, try /usr/xpg4/bin/sed (NOT bib !).
# 11  
RudiC:

Thanks for new input. I tried and got this output,

Code:
/home/oracle/>/usr/xpg4/bin/sed "s/\(JUN\|JUL\|AUG\)/$NEWDATE" test4.txt
sed: command garbled: s/\(JUN\|JUL\|AUG\)/01-OCT-2019

Now the problem is that sed cannot find or match the month. If sed match the old date, then new date will replace it. I will continue to debug step by step. Thanks a lot.
# 12  
You're missing a / at the end of your s command:


Code:
/home/oracle/>/usr/xpg4/bin/sed "s/\(JUN\|JUL\|AUG\)/$NEWDATE/" test4.txt

# 13  
RudiC:

Yes. I missed a / and tested again. The result is still not working. It seems that sed cannot find MON in lines. This part-s/\(JUN\|JUL\|AUG\) is not functioning. see output,

Code:
/home/oracle> /usr/xpg4/bin/sed "s/\(JUN\|JUL\|AUG\)/$NEWDATE/" test4.txt
       ep.begin_date, ep.end_date, ep.facility_code,
AND    ep.begin_date <= '01-JUL-2019'
       ep.begin_date, ep.end_date, ep.facility_code,
AND    ep.begin_date <= '01-JUL-2019'
       ep.begin_date, ep.end_date, ep.facility_code,
AND    ep.begin_date <= '01-JUL-2019'

Thanks.
# 14  
Didn't you say you're doing a step by step debug?
Try

Code:
sed "s/\(JUL\)/XXX/" file

Read your sed version's man page!
