How to extract the the first of two identical sentences in a log file using awk

I have a log file which repeats the same message twice.

I would like to save this message in a variable to use later in the script.

The following awk expression will pull the first of the two sentences out for you to save in a variable:

analyze_status=`cat /u01/oracle/cfgtoollogs/upgrade/auto/autoupgrade.log | grep 'ANALYZE and FIXUPS' | awk 'NR==1'`

Output of the command is:

echo $analyze_status
ANALYZE and FIXUPS modes are not run when converting a Non-CDB database to a PDB

Without the NR==1 I get the same sentence repeated twice:

ANALYZE and FIXUPS modes are not run when converting a Non-CDB database to a PDB ANALYZE and FIXUPS modes are not run when converting a Non-CDB database to a PDB
