Retrieve the Following Occurrence of the String 'PWD' Once the Given String is Located

Below is my sample test.log file export SQRDIR=/v/orahome/Middleware/Oracle/bin64 export OID=ap0092 export PWD=pass1 export FDPWD=pass1 export AP0085_PWD=pass1 export SVR=AFFPROD export TWO_TASK=db01 export EF_OID=AP0093 export EF_PWD=pass2 export CCC_PER_OID=CCC_JAS export CCC_PER_PWD=pass3 export CAN_PER_OID=CAN_JAS export CAN_PER_PWD=pass4 ################################################### The user inputs ap0092. Upon this input, I need to search for the first occurrence of PWD after the first occurrence of the search string i.e. =ap0092 Thus, the desired output will be pass1 Likewise, for CCC_JAS the desired output will be pass3 I need the solution for Solaris OS. I was doing grep -A 1 [for non-Solaris] to get the next line but do not know how to search if the desired line may not be the very next line. Please note: There may be multiple lines or Whiteline between export OID=ap0092 and export PWD=pass1 Kindly suggest.
