I am trying to remove a line feed (\n) within a fixed width record. I tried the tr -d ‘\n' command, but it also removes the record delimiter. Is there a way to remove the line feed without removing the record delimiter? (10 Replies)
Hi All,
I have created a script which generates FIXED-WIDTH file by executing Oracle query.
SELECT RPAD(NVL(col1,CHR(9)),20)||NVL(col2,CHR(9))||NVL(col3,CHR(9) FROM XYZ
It generates the data file with proper alignment. But if same file i transfer to windows server or Mainframe... (5 Replies)

NETLINK(3) Linux Programmer's Manual NETLINK(3)NAME
netlink - Netlink macros
SYNOPSIS
#include <asm/types.h>
#include <linux/netlink.h>
int NLMSG_ALIGN(size_t len);
int NLMSG_LENGTH(size_t len);
int NLMSG_SPACE(size_t len);
void *NLMSG_DATA(struct nlmsghdr *nlh);
struct nlmsghdr *NLMSG_NEXT(struct nlmsghdr *nlh, int len);
int NLMSG_OK(struct nlmsghdr *nlh, int len);
int NLMSG_PAYLOAD(struct nlmsghdr *nlh, int len);
DESCRIPTION
<linux/netlink.h> defines several standard macros to access or create a netlink datagram. They are similar in spirit to the macros defined
in cmsg(3) for auxiliary data. The buffer passed to and from a netlink socket should be accessed using only these macros.
NLMSG_ALIGN()
Round the length of a netlink message up to align it properly.
NLMSG_LENGTH()
Given the payload length, len, this macro returns the aligned length to store in the nlmsg_len field of the nlmsghdr.
NLMSG_SPACE()
Return the number of bytes that a netlink message with payload of len would occupy.
NLMSG_DATA()
Return a pointer to the payload associated with the passed nlmsghdr.
NLMSG_NEXT()
Get the next nlmsghdr in a multipart message. The caller must check if the current nlmsghdr didn't have the NLMSG_DONE set--this
function doesn't return NULL on end. The len argument is an lvalue containing the remaining length of the message buffer. This
macro decrements it by the length of the message header.
NLMSG_OK()
Return true if the netlink message is not truncated and is in a form suitable for parsing.
NLMSG_PAYLOAD()
Return the length of the payload associated with the nlmsghdr.
CONFORMING TO
These macros are nonstandard Linux extensions.
NOTES
It is often better to use netlink via libnetlink than via the low-level kernel interface.
