I have the following two statements in a shell script:

 32 /usr/local/mysql/bin/mysql -u root files -e "TRUNCATE path"
 33 /usr/local/mysql/bin/mysql -u root files -e "
 34     LOAD DATA INFILE '/tmp/files.txt'
 35     INTO TABLE path
 36     FIELDS TERMINATED BY ','
 37       (size, @d2, @d3, @d4, @d5, path)
 38     SET last_modified=str_to_date(CONCAT(@d2, ',', @d3, ',', @d4, ',', @d5), '%b,%d,%T,%Y');"
 39 }

How would I make it such that the commands starting on line 32 & 32 either both work or both fail (a transaction) ?

    What you need is a transaction:

    BEGIN;
LOAD DATA INFILE ...;
SET ...;
COMMIT;

    Unless you COMMIT the transaction, the database will not have those rows loaded or the columns updated.

    As a note, some operations cannot be “transactionalized” in MySQL, and this includes schema alterations as well as TRUNCATE TABLE. Some statements will force a commit regardless of your intentions, so be careful to avoid those when trying to create a transaction.
