I amfacing an error working with sed on files.
We have this core running successfully on OracleLinux 7.9 but onOracleLinux 8.9 the same code fails with invalid range end

sed -r -f ./sed/transform-diff.sed < 15-diffToUpdate.xml > 15-diffToUpdate.xml.tmp
sed: file ./sed/transform-diff.sed line 11: Invalid range end

where transform-diff-sed is:

# sed script to transform generated Liquibase diff file

# Problem to solve: If a column is dropped, a RDBM drops as well every index, that uses these columns. In the
# Liquibase diff script, columns are dropped first, indexes later. In the previously described case, an index
# might already be deleted and the update might fail.
# Solution: Put every <dropIndex> in a separate <changeSet>, containing a <indexExists> preCondition that
# only executes the <dropIndex> if it still exists.
/<changeSet/ {
    N
    s%([ t]*)<changeSet author="([a-zA-Z ()]*)" id="([a-zA-Z0-9-]*)">[ tn]*(<dropIndex indexName="([a-zA-Z0-9_]*)"[a-zA-Z_-=" ]*>)%1<changeSet author="2" id="3a">n11<preConditions onFail="CONTINUE">n111<indexExists indexName="5" />n11</preConditions>n114n1</changeSet>n1<changeSet author="2" id="3b">%g
}

# Problem to solve: Liquibase diff reads from type FLOAT not the precision but the the required bytes adds
# this information to its change log. A FLOAT (with default precision of 126) is transformed to a FLOAT(22),
# which is too short. By removing all precision information in the generated diff file, we avoid this
# problem.
/type="FLOAT(/ {
    s%type="FLOAT([0-9]*)"%type="FLOAT"%g
}

Any hints how to proceed ? The sed commands were developed years ago and could been changed. I do need to get it running

I isolated the code and get it running on two seperate machines

1.) Oracle Linux 7.9 –> works fine, Output-File is filled

2.) Oracle Linux 8.9 –> error message, Output-File is empty
