Top Forums Shell Programming and Scripting Swap usage by top and free command doesn't match Post 302596945 by admin_xor on Wednesday 8th of February 2012 06:14:28 PM

This entirely depends on the perspective the program is looking from. Not only free top, people found discrepancies among the outputs of sar -r, vmstat, ps aux.

But, as far as my knowledge goes, free command shows output using /proc/meminfo file. That's a direct output from kernel and ought to be more correct one.

mysqld_multi --config-file=... Alternative config file. NOTE: This will not affect this program's own options (group [mysqld_multi]), but only groups [mysqld#]. Without this option everything will be searched from the ordinary my.cnf file. --example Give an example of a config file. --help Print this help and exit. --log=... Log file. Full path to and the name for the log file. NOTE: If the file exists, everything will be appended. --mysqladmin=... mysqladmin binary to be used for a server shutdown. --mysqld=... mysqld binary to be used. Note that you can give mysqld_safe to this option also. The options are passed to mysqld. Just make sure you have mysqld in your environment variable PATH or fix mysqld_safe. --no-log Print to stdout instead of the log file. By default the log file is turned on. --password=... Password for user for mysqladmin. --tcp-ip Connect to the MySQL server(s) via the TCP/IP port instead of the UNIX socket. This affects stopping and reporting. If a socket file is missing, the server may still be running, but can be accessed only via the TCP/IP port. By default connecting is done via the UNIX socket. --user=... MySQL user for mysqladmin. --version Print the version number and exit. NOTE
