GNU Parallel Bug Reports unmasked passwd with mysql in parallel

[Hal Ebi]

Hi Ole,

parallel --version
GNU parallel 20130922

Recently I have been setting up parallel for pipelines to work with 
mysql and it runs these great. My problem is that when I list the 
running processes initiated by parallel (e.g. with ps or top), "parallel 
shows" the commands as they are run without masking the password for the 
mysql user. This is a problem as anyone with access to the server I am 
working on can freely see the connection parameters along with my password.

An example:
when I run mysql or mysqldump alone (not from parallel) the password is 
always masked out.
E.g.:
When I am running the following:

mysqldump --opt -h $DBHOST -P $DBPORT -u $DBUSER -p$DBPASS testdb1 > testdb1.sql

ps shows:

mysqldump --opt -h myhost -P 3306 -u testuser -px xxxxxx testdb1


when I try to do the same using the following command with parallel:

cat testlist | parallel -j 4 "mysqldump --opt -h $DBHOST -P $DBPORT -u $DBUSER -p$DBPASS {} 
> {}.sql" &

ps shows the following:

\_ perl /usr/local/bin/parallel -j 4 mysqldump --opt -h Ris-lx06 -P 3306 
-u testuser -p2AtP8!z {} > {}.sql
    \_ /bin/bash -c mysqldump --opt -h Ris-lx06 -P 3306 -u testuser 
-p2AtP8!z testdb1 > testdb1.sql
    |   \_ mysqldump --opt -h Ris-lx06 -P 3306 -u testuser -px xxxxxx 
testdb1
    \_ /bin/bash -c mysqldump --opt -h Ris-lx06 -P 3306 -u testuser 
-p2AtP8!z testdb2 > testdb2.sql
    |   \_ mysqldump --opt -h Ris-lx06 -P 3306 -u testuser -px xxxxxx 
testdb2
    \_ /bin/bash -c mysqldump --opt -h Ris-lx06 -P 3306 -u testuser 
-p2AtP8!z testdb3 > testdb3.sql
    |   \_ mysqldump --opt -h Ris-lx06 -P 3306 -u testuser -px xxxxxx 
testdb3
    \_ /bin/bash -c mysqldump --opt -h Ris-lx06 -P 3306 -u testuser 
-p2AtP8!z testdb4 > testdb4.sql
        \_ mysqldump --opt -h Ris-lx06 -P 3306 -u testuser -px xxxxxx 
testdb4

Is there a way to make parallel to pass the passwords on silently to mysql?

Thank you.
