Problem with Argument Passing
Post 302088572 by A_Rod on Wednesday 13th of September 2006 09:24:17 AM

I percieved that initially, but the requirement is in the direction that we should be able to get only vmstat or iostat or both, from the script.
Also the argument passing needs to be v for vmstat, i for iostat, n for netstat etc./ .
Hopefully i'll pull out with some solution !!

I'm new to Shell scripting. In my shell script for Bourne shell, the script accepts a date parameter which is optional. If the value is supplied, the supplied value should be assigned to a variable. If not, the current date will be assigned to the variable. My script is like this.

iostat
iostat(1) General Commands Manual iostat(1) Name iostat - report I/O statistics Syntax iostat [ -c ] [ -t ] [ disknames ] [ interval ] [ count ] Description The command reports I/O statistics for terminals, disks and cpus. For terminals the number of input and output characters are counted. For disks the number of 512 byte blocks per second and number of transfers per second are displayed. For cpus, it provides the percentage of time the system has spent in user mode, in user mode running low priority (niced) processes, in system mode, and idling. On multipro- cessor systems these cpu statistics represent a cumulative summary of all the cpus. The optional disknames argument causes disk statistics to be displayed for the specified disks. If this argument is not specified then disk statistics will be displayed for the first 3 disks only. The optional interval argument causes to report once each interval seconds. The first report is for all time since a reboot and each sub- sequent report is for the last interval only. The optional count argument restricts the number of reports. Options -c Displays the percentage of time each cpu spent in user mode, running low priority (nice'd) processes, in system mode, and idling. -t Displays the number of characters read from and written to terminals. Examples This example will cause cpu and disk statistics for the 5 disks ra0, ra1, ra2, ra3, and ra4. iostat ra0 ra1 ra2 ra3 ra4 This example will cause cpu, terminal, and disk statistics for ra0 to be displayed and updated every 2 seconds. iostat -t ra0 2 Files See Also vmstat(1), cpustat(1) iostat(1)
