I have,
LIST="a b c d e"
for word in $LIST
do
echo $word
done
would give me
a
b
c
d
e
With the first iteration of the for loop, I get "a" as the result.
Is it possible that I get both "a" and "b" in only the first iteration.
In the next iteration I get "c" and "d" and so on.... (2 Replies)

Hi Admin, i just noticed that when I do postings, the number does not increment. eg :
Post A -Total Posts 312
Post B - Total Posts 312
Post C - Total Posts 313
Post D - Total Posts 313
Why is this so? Can you kindly check this out? Thank you. (5 Replies)
I'm currently trying to write a ksh or csh script that would change the name of a file found in directories and attach to the name an incrementing three digit number.
I know how to write a script that will go:
000, 001, 002, 003, etc
The twist is I need more increments then allowed by a 3... (11 Replies)
Hi,
want to increment a variable in a for loop like this:
for (( c=$total-1; c>=0; c-- ))
do
if ;
then
maximo=$valores
fi
done
But it gives the error:
No such file or directory
How can i do this only incrementing the c variable?
Thanks (8 Replies)
Hi All,
I require some help with the below:
I am trying to incriment the ascii value of a letter and then print it.
So basically "a" becomes "b" and "z" becomes "A".
Does anyone have any pointers?

Hello Everyone,
I have been trying to complete a shell script where, I need to increment the date depending on the file (depending on the date) availability on the remote server.
i.e.
Basically, I will be passing a counter (like parameter 1 or 2 or 3 or 4).
First I will check for the... (1 Reply)

I have a date variable like 2012-12-31 ( YYYY -MM -DD ) in flat file and it has to be incremtented by 1 every time i run the script

I386_PMC_INFO(2) BSD/i386 System Calls Manual I386_PMC_INFO(2)NAME
i386_pmc_info, i386_pmc_startstop, i386_pmc_read -- interface to CPU performance counters
LIBRARY
i386 Architecture Library (libi386, -li386)
SYNOPSIS
#include <sys/types.h>
#include <machine/sysarch.h>
#include <machine/specialreg.h>
int
i386_pmc_info(struct i386_pmc_info_args *ia);
int
i386_pmc_startstop(struct i386_pmc_startstop_args *ssa);
int
i386_pmc_read(struct i386_pmc_read_args *ra);
DESCRIPTION
These functions provide an interface to the CPU performance counters on the 586-class and 686-class processors.
i386_pmc_info() will return information about the available CPU counters. The information is returned in ia having the following structure:
struct i386_pmc_info_args {
int type;
int flags;
};
The type member describes the class of performance counters available. Valid values are:
PMC_TYPE_NONE No PMC support
PMC_TYPE_I586 586-class CPUs
PMC_TYPE_I686 686-class Intel CPUs
PMC_TYPE_K7 686-class AMD CPUs
The flags member describes additional capabilities of the processor. Valid values are:
PMC_INFO_HASTSC CPU has time-stamp counter
i386_pmc_startstop() is used to start and stop the measurement of the CPU performance counters. The argument ssa has the following struc-
ture:
struct i386_pmc_startstop_args {
int counter;
uint64_t val;
uint8_t event;
uint8_t unit;
uint8_t compare;
uint8_t flags;
};
The counter specified by the member counter is started if the member flags has PMC_SETUP_KERNEL or PMC_SETUP_USER set, otherwise the counter
is stopped. The initial value of the counter is set to val. Additional values for the flags member are PMC_SETUP_EDGE and PMC_SETUP_INV.
The event member specifies some event written to the control register. The unit member specifies the measurement units. The compare member
is a mask for the counter.
i386_pmc_read() will return information about a specific CPU counter measured during the last measurement period determined by the calling of
i386_pmc_startstop(). The information is returned in ra having the following structure:
struct i386_pmc_read_args {
int counter;
uint64_t val;
uint64_t time;
};
The counter to read should be specified by the counter member. Counters are numbered from 0 to PMC_NCOUNTERS. The value of the counter is
returned in the val member. The time since epoch, measured in CPU clock cycles, is returned in the time member.
RETURN VALUES
Upon successful completion zero is returned, otherwise -1 is returned on failure.
