Staring at (and comparing) the resultant scripts again, the $tablename is not used at all, and the actual $agname value is used for the input file name only. Why all that effort and complexity if you could have one single constant(!) script and call it with a parameter indicating the input file?
Like
, and in /tmp/final/scripts/ALL_retrieval.ksh you read your data from $1.
Writing a ksh script. If someone starts a process with:

How can I grab 'date.log' name as a variable in test.ksh?

Hi,
I did the below.
$ print "\\n"
$
I am curious, why does \\n give two new lines? I would have thought that the first \ would escape the second \, and so we'd get \n printed. But we didn't.
Any ideas?
Thanks. (7 Replies)

Hi all,
The below command tries to copy ".tgz" instead of "hello_test.tgz" -- It seems as if the underscore gets in the way. I tried with different ways of using quotes, with no luck, unfortunately...it's probably very simple, but may I ask how this would be done:
How would the below be... (3 Replies)
Hello All,
I'm trying to write a script that will perform a dynamic match (of a dynamic variable) and set a variable to have the resulting (match) value.
The idea is that the environment variable to check ($1) and the regular expression to use ($2) are given as parameters.
For example,... (5 Replies)

rmvb
rmvb(9F) Kernel Functions for Drivers rmvb(9F)NAME
rmvb - remove a message block from a message
SYNOPSIS
#include <sys/stream.h>
mblk_t *rmvb(mblk_t *mp, mblk_t *bp);
INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI).
PARAMETERS
mp Message from which a block is to be removed. mblk_t is an instance of the msgb(9S) structure.
bp Message block to be removed.
DESCRIPTION
The rmvb() function removes a message block (bp) from a message (mp), and returns a pointer to the altered message. The message block is
not freed, merely removed from the message. It is the module or driver's responsibility to free the message block.
RETURN VALUES
If successful, a pointer to the message (minus the removed block) is returned. The pointer is NULL if bp was the only block of the message
before rmvb() was called. If the designated message block (bp) does not exist, -1 is returned.
CONTEXT
The rmvb() function can be called from user, interrupt, or kernel context.
EXAMPLES
This routine removes all zero-length M_DATA message blocks from the given message. For each message block in the message, save the next
message block (line 10). If the current message block is of type M_DATA and has no data in its buffer (line 11), then remove it from the
message (line 12) and free it (line 13). In either case, continue with the next message block in the message (line 16).
