Hello,
Can somebody help me to solve this inconsistent data issue. I have a pipe delimiter file and one of the column is a comment. I am trying to concatenate into one single sentence. For instance, I have a file actually with 2 records but the way it considers the first record is as different rows and hence loads into the table as different records. In the sample below, 123 and 789 are two different records.
Code:
123|efg|"Try to solve.
This is a unix script. Trying to concatenate.
It seems to be simple but not as simple once I start scripting.
Sincerly,
XYZ
ABC"|5|3|6 months
789|def|"Better way to solve this issue."|4|6|7 years
This is how it has to look.
Code:
abc|efg|"Try to solve. This is a unix script. Trying to concatenate. It seems to be simple but not as simple once I start scripting. Sincerly, XYZ ABC"|5|3|6 months
789|def|"Better way to solve this issue."|4|6|7 years
I first tried to remove the blank space using
Code:
sed '/^$/d' t1.txt > t2.txt
Then I couldn't figure out how to remove spaces after a period and concatenate the next sentence.
I would really appreciate any input on resolving this.

pipe
PIPE(2) BSD System Calls Manual PIPE(2)NAME
pipe -- create descriptor pair for interprocess communication
SYNOPSIS
#include <unistd.h>
int
pipe(int *fildes);
DESCRIPTION
The pipe() function creates a pipe, which is an object allowing unidirectional data flow, and allocates a pair of file descriptors. The
first descriptor connects to the read end of the pipe, and the second connects to the write end, so that data written to fildes[1] appears on
(i.e., can be read from) fildes[0]. This allows the output of one program to be sent to another program: the source's standard output is set
up to be the write end of the pipe, and the sink's standard input is set up to be the read end of the pipe. The pipe itself persists until
all its associated descriptors are closed.
A pipe whose read or write end has been closed is considered widowed. Writing on such a pipe causes the writing process to receive a SIGPIPE
signal. Widowing a pipe is the only way to deliver end-of-file to a reader: after the reader consumes any buffered data, reading a widowed
pipe returns a zero count.
RETURN VALUES
On successful creation of the pipe, zero is returned. Otherwise, a value of -1 is returned and the variable errno set to indicate the error.
ERRORS
The pipe() call will fail if:
[EMFILE] Too many descriptors are active.
[ENFILE] The system file table is full.
[EFAULT] The fildes buffer is in an invalid area of the process's address space.

A pipe() function call appeared in Version 6 AT&T UNIX.
