I have a script which selects two 'sets' of system LVM device files from a tabular file 'mapfile' using awk :
LIVELV=`awk '{print($1)}' mapfile`
BCVLV=`awk '{print($3)}' mapfile`
I wanted to pass these 'sets' into an LVM command 'loop' along the lines of :
lvmerge $BCVLV $LIVELV

Hi,
I have two variables like below which will always be of the same size
a=1:2:3
b=A:B:C
I need to use a for/while loop that will have both the variables available. I cannot use an array here and will probably might iterate through the variable as echo $a | tr ':' '\n' and thus iterate... (5 Replies)
Hi,
I need to pass the multiple values of src1 to another variable. I managed to print it but not sure how to assign it to a variable in a loop.
src1=01,02,03
echo $src1|awk 'BEGIN {FS=","} {for(i=1;i<=NF;i++) print $i}'
I need to pass the value as
src2=01
src2=02
src2=03
Thanks... (4 Replies)
Hi,
I managed to read and print variable as shown in the below code.

falloc
MALLOC(3F)MALLOC(3F)NAME
malloc, free, falloc - memory allocator
SYNOPSIS
subroutine malloc (size, addr)
integer size, addr
subroutine free (addr)
integer addr
subroutine falloc (nelem, elsize, clean, basevec, addr, offset)
integer nelem, elsize, clean, addr, offset
DESCRIPTION
Malloc, falloc and free provide a general-purpose memory allocation package. Malloc returns in addr the address of a block of at least
size bytes beginning on an even-byte boundary.
Falloc allocates space for an array of nelem elements of size elsize and returns the address of the block in addr. It zeros the block if
clean is 1. It returns in offset an index such that the storage may be addressed as basevec(offset+1) ... basevec(offset+nelem). Falloc
gets extra bytes so that after address arithmetic, all the objects so addressed are within the block.
The argument to free is the address of a block previously allocated by malloc or falloc; this space is made available for further alloca-
tion, but its contents are left undisturbed. To free blocks allocated by falloc, use addr in calls to free, do not use basevec(offset+1).
Needless to say, grave disorder will result if the space assigned by mallocorfalloc is overrun or if some random number is handed to free.
DIAGNOSTICS
Malloc and falloc set addr to 0 if there is no available memory or if the arena has been detectably corrupted by storing outside the bounds
of a block.
The following example shows how to obtain memory and use it within a subprogram:
integer addr, work(1), offset
...
call falloc ( n, 4, 0, work, addr, offset )
do 10 i = 1, n
work(offset+i) = ...
10 continue
The next example reads in dimension information, allocates space for two arrays and two vectors, and calls subroutine doit to do the compu-
tations:
integer addr, dummy(1), offs
read *, k, l, m
indm1 = 1
indm2 = indm1 + k*l
indm3 = indm2 + l*m
indsym = indm3 + k*m
lsym = n*(n+1)/2
indv = indsym + lsym
indtot = indv + m
call falloc ( indtot, 4, 0, dummy, addr, offs )
call doit( dummy(indm1+offs), dummy(indm2+offs),
. dummy(indm3+offs), dummy(indsym+offs),
. dummy(indv +offs), m, n, lsym )
end
subroutine doit( arr1, arr2, arr3, vsym, vec, m, n, lsym )
real arr1(k,l), arr2(l,m), arr3(k,m), vsym(lsym), v2(m)
...
