Hello all,
I want to transpose the rows of a file to the columns (every characters include spaces), i.e.:
input:
abcdefg
123 456
output:
a1
b2
c3
d
e4
f5
g6
I wrote a script:
#!/bin/csh -f (15 Replies)
Hi ALL
I have one input file say FILE1 which looks as below.
a=1
b=2
c=3
a=4
b=5
c=6

.
Here a,b,c...etc are variable names.
The output file(FILE2) should look like
1,2,3
4,5,6

Hi I have an input file and I want to transpose it but I need to take care that if any field is missing for a record it should be popoulated with space for that field - using a shell script

Hi Friends,
I have a file with a structure like this:
<file1.csv>
field1,field2,field3,field4,field5,field6,field7,field8,field9,field10,field11,field12
Few Salient points on the file's structure

Hello,
I have a text file with 148 rows and 2532691 columns. I need to transpose the data. The command that I am using is
awk '
{
for (i=1; i<=NF; i++) {
a = $i
}
}
NF>p { p = NF }
END {
for(j=1; j<=p; j++) {
str=a
for(i=2; i<=NR; i++){

getdelim
GETLINE(3) Linux Programmer's Manual GETLINE(3)NAME
getline, getdelim - delimited string input
SYNOPSIS
#define _GNU_SOURCE
#include <stdio.h>
ssize_t getline(char **lineptr, size_t *n, FILE *stream);
ssize_t getdelim(char **lineptr, size_t *n, int delim, FILE *stream);
DESCRIPTION
getline() reads an entire line, storing the address of the buffer containing the text into *lineptr. The buffer is null-terminated and
includes the newline character, if a newline delimiter was found.
If *lineptr is NULL, the getline() routine will allocate a buffer for containing the line, which must be freed by the user program. Alter-
natively, before calling getline(), *lineptr can contain a pointer to a malloc()-allocated buffer *n bytes in size. If the buffer is not
large enough to hold the line read in, getline() resizes the buffer to fit with realloc(), updating *lineptr and *n as necessary. In either
case, on a successful call, *lineptr and *n will be updated to reflect the buffer address and size respectively.
getdelim() works like getline(), except a line delimiter other than newline can be specified as the delimiter argument. As with getline(),
a delimiter character is not added if one was not present in the input before end of file was reached.
RETURN VALUE
On success, getline() and getdelim() return the number of characters read, including the delimiter character, but not including the termi-
nating null character. This value can be used to handle embedded null characters in the line read.
Both functions return -1 on failure to read a line (including end of file condition).
ERRORS
EINVAL Bad parameters (n or lineptr is NULL, or stream is not valid).
EXAMPLE
#define _GNU_SOURCE
#include <stdio.h>
#include <stdlib.h>
int main(void)
{
FILE * fp;
char * line = NULL;
size_t len = 0;
ssize_t read;
fp = fopen("/etc/motd", "r");
if (fp == NULL)
exit(EXIT_FAILURE);
while ((read = getline(&line, &len, fp)) != -1) {
printf("Retrieved line of length %zu :
", read);
printf("%s", line);
}
if (line)
free(line);
return EXIT_SUCCESS;
}
CONFORMING TO
Both getline() and getdelim() are GNU extensions. They are available since libc 4.6.27.
