Scripts are fine, but I just want to set a limitation of commands that users can executed @ given period of time. For example, I don't want a user executes 100000000 commands in 1 mins. Is there a command for this or I have to make a script to realize it?

truncate
TRUNCATE(1) User Commands TRUNCATE(1)
NAME
truncate - shrink or extend the size of a file to the specifed size
SYNOPSIS
truncate OPTION... FILE...
DESCRIPTION
Shrink or extend the size of each FILE to the specified size
A FILE argument that does not exist is created.
If a FILE is larger than the specified size, the extra data is lost. If a FILE is shorter, it is extended and the extended part (hole)
reads as zero bytes.
Mandatory arguments to long options are mandatory for short options too.
-c, --no-create
do not create any files
-o, --io-blocks
Treat SIZE as number of IO blocks instead of bytes
-r, --reference=FILE
use this FILE's size
-s, --size=SIZE
use this SIZE
--help display this help and exit
--version
output version information and exit
SIZE is a number which may be followed by one of the following suffixes: KB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G, T, P,
E, Z, Y.
SIZE may also be prefixed by one of the following modifying characters: `+' extend by, `-' reduce by, `<' at most, `>' at least, `/' round
down to multiple of, `%' round up to multiple of.
Note that the -r and -s options are mutually exclusive.
