The following works for me: mysql -u ‘root’ -h 8.8.8.88 mo -e ‘UPDATE `path_last_updated`

The following works for me:

mysql -u 'root' -h 8.8.8.88 mo -e 'UPDATE `path_last_updated` 
    SET timestamp="2012-01-03 00:00:00"'

However, the following does not:

TIMESTAMP=`date "+%Y-%m-%d-%T"`
mysql -u 'root' -h 8.8.8.88 mo -e 'UPDATE `path_last_updated` 
    SET timestamp=$TIMESTAMP'

How would I insert the timestamp from unix into my mysql table?

Update:

TIMESTAMP=`date "+%Y-%m-%d %T"`
mysql -u 'root' -h 8.8.8.88 mo -e "UPDATE `path_last_updated` 
    SET timestamp='$TIMESTAMP'"

    Shell variable interpolation only works between double quotes (“), not single (‘). You’ve also got backticks in there, which in a double-quoted string will be treated as an embedded shell command.

    Try:

    mysql -u 'root' -h 8.8.8.88 mo -e "UPDATE \`path_last_updated\`
    SET timestamp='$TIMESTAMP'"

    Also, fwiw, you have an extra dash (-) in your format for the date command, between the %d and %T.
