-----------------------------------
TIMETHIS : Command Timing Utility
-----------------------------------
Usage : TIMETHIS "command"
TimeThis executes the command specified by its arguments, then reports its
run time in HH:MM:SS.TTT format. Quotes around the command are required only
when the command involves redirection via <, >, >>, or |, etc. Quotes ensure
that the redirection is applied to the command being timed, rather than the
TimeThis command itself.
Examples :
TimeThis DIR C:\WINNT
TimeThis "DIR C:\WINNT | MORE"
Usage: TIMEIT [-f filename] [-a] [-c] [-i] [-d] [-s] [-t] [-k keyname | -r keyna
me] [-m mask] [commandline...]
where: -f specifies the name of the database file where TIMEIT
keeps a history of previous timings. Default is .\timeit.dat
-k specifies the keyname to use for this timing run
-r specifies the keyname to remove from the database. If
keyname is followed by a comma and a number then it will
remove the slowest (positive number) or fastest (negative)
times for that keyname.
-a specifies that timeit should display average of all timings
for the specified key.
-i specifies to ignore non-zero return codes from program
-d specifies to show detail for average
-s specifies to suppress system wide counters
-t specifies to tabular output
-c specifies to force a resort of the data base
-m specifies the processor affinity mask
