sfeed_update: merge: change the default to use the last record |
|
|
|
In many cases it makes sense to use the last record. |
|
|
|
Most implementations using sort -u use a stable sort and use the first record |
|
found by the specified key (where the key are the fields: id, title, link). |
|
|
|
This means it kept the record found in the old file and not update the last |
|
content. |
|
|
|
Swap the default to use the last record instead of the first. |
|
|
|
An alternative in awk: |
|
|
|
merge() { |
|
LC_ALL=C awk -F '\t' '!x[$6 "\t" $2 "\t" $3]++' "$3" "$2" |
|
} |
|
|
|
Thanks Ivo Cicchese for the feedback! |
