I have an awk statement that works but I am calling awk twice and I know there has to be a way to combine the two statements into one. The purpose is to pull out just the ip address from loopback1.

I have a pretty simple script below:
#!/bin/sh
for i in *.cfg
do
temp=`awk '/^InputDirectory=/' ${i}`
input_dir=`echo ${temp} | awk '{ print substr( $0, 16) }'`
echo ${input_dir}
done
As you can see its opening each cfg file and searching for the line that has "InputDirectory="... (3 Replies)

Hi,
I have the following two awk statements which I'd like to consolidate into one by piping the output from the first into the second awk statement (rather than having to write kat.txt out to a file and then reading back in).
awk 'BEGIN {FS=OFS=" "} {printf("%s ", $2);for (x=7; x<=10;... (3 Replies)

getdelim
GETLINE(3) BSD Library Functions Manual GETLINE(3)NAME
getdelim, getline -- get a line from a stream
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <stdio.h>
ssize_t
getdelim(char ** restrict linep, size_t * restrict linecapp, int delimiter, FILE * restrict stream);
ssize_t
getline(char ** restrict linep, size_t * restrict linecapp, FILE * restrict stream);
DESCRIPTION
The getdelim() function reads a line from stream, delimited by the character delimiter. The getline() function is equivalent to getdelim()
with the newline character as the delimiter. The delimiter character is included as part of the line, unless the end of the file is reached.
The caller may provide a pointer to a malloced buffer for the line in *linep, and the capacity of that buffer in *linecapp. These functions
expand the buffer as needed, as if via realloc(). If linep points to a NULL pointer, a new buffer will be allocated. In either case, *linep
and *linecapp will be updated accordingly.
RETURN VALUES
The getdelim() and getline() functions return the number of characters written, excluding the terminating NUL character. The value -1 is
returned if an error occurs, or if end-of-file is reached.
EXAMPLES
The following code fragment reads lines from a file and writes them to standard output. The fwrite() function is used in case the line con-
tains embedded NUL characters.
char *line = NULL;
size_t linecap = 0;
ssize_t linelen;
while ((linelen = getline(&line, &linecap, fp)) > 0)
fwrite(line, linelen, 1, stdout);
ERRORS
These functions may fail if:
[EINVAL] Either linep or linecapp is NULL.
[EOVERFLOW] No delimiter was found in the first SSIZE_MAX characters.
These functions may also fail due to any of the errors specified for fgets() and malloc().
SEE ALSO fgetln(3), fgets(3), malloc(3)STANDARDS
The getdelim() and getline() functions conform to IEEE Std 1003.1-2008 (``POSIX.1'').
HISTORY
These routines first appeared in FreeBSD 8.0.
BUGS
There are no wide character versions of getdelim() or getline().
