vmstat -SM doesn't work but vmstat -S M does
Issue
- The vmstat program does not use the standard getopt and, consequently, it does not work quite like a program should with regards to command line options.
-
For example, note that the "S M" arguments given to vmstat will not work unless a space is inserted between them. Applications should be able to specify the option
and option-argument in the same argument string without intervening <blank> characters:#vmstat -SM 5 -S requires k, K, m or M (default is kb) #vmstat -S M 5 procs -----------memory---------- ---swap-- -----io---- --system-- -----cpu------ r b swpd free buff cache si so bi bo in cs us sy id wa st 0 0 230 21 72 234 0 0 4 5 6 0 5 1 94 0 0 0 0 230 21 72 234 0 0 0 6 1059 802 1 0 99 0 0
