Hello,

Could you please try the following code, hope this helps in variable named s1 you can set the date value which you want to get in output.

Code:
awk -F"=" -vs1="20140827" '/^\$\$TODAY/ {$2=s1} 1' OFS="="  Filename

output will be as follows.

Code:
SomeTextGoesHere
[ASD.EXAMPLE@ABCD]
$$TODAY_DT=20140827

[FGH.EXAMPLE@ABCD]
$$TODAY_DT=20140827

[QWE.EXAMPLE@ABCD]
$$TODAY_DT=20140827

If you want to give today's date as passing variable then following may help.

Code:
awk -F"=" -vs1="$(date +%Y%m%d)" '/^\$\$TODAY/ {$2=s1} 1' OFS="="  filename

Thanks,
R. Singh
