The command    show full processlist   can be replaced by   SELECT   FROM information schema processlist   but if you go with the latter version you can add WHERE clause to it   SELECT   FROM information schema processlist WHERE  INFO  LIKE  SELECT       For more information visit this

We don t have a newer version of MySQL yet  so I was able to do this  works only on UNIX     host maindb   echo  show full processlist G    mysql -h host   grep -B 6 -A 1 Locked   The above will query for all locked sessions  and return the information and SQL that is involved      So- assuming you wanted to query for sessions that were sleeping     host maindb    echo  show full processlist G    mysql -h host   grep -B 6 -A 1 Sleep   Or  assuming you needed to provide additional connection parameters for MySQL     host maindb    user me    password mycoolpassword     echo  show full processlist G    mysql -h host -u user -p password   grep -B 6 -A 1 Locked   With a couple of tweaks  I m sure a shell script could be easily created to query the processlist the way you want it

Newer versions of SQL support the process list in information schema   SELECT   FROM INFORMATION SCHEMA PROCESSLIST   You can ORDER BY in any way you like     The INFORMATION SCHEMA PROCESSLIST table was added in MySQL 5 1 7   You can find out which version you re using with   SELECT VERSION

You can just capture the output and pass it through a filter  something like   mysql show processlist       grep -v      - -        grep -v     Id        sort -n -k12   The two greps strip out the header and trailer lines  others may be needed if there are other lines not containing useful information  and the sort is done based on the numeric field number 12  I think that s right    This one works for your immediate output   mysql show processlist       grep -v      - -        grep -v     Id        grep -v     0-9  0-9   rows in set         grep -v            sort -n -k12

Another useful tool for this from the command line interface  is the pager command   eg  pager grep -v Sleep   more  show full processlist    Then you can page through the results   You can also look for certain users  IPs or queries with grep or sed in this way   The pager command is persistent per session
