Find header in a text file and prepend it to all lines until another header is found
I've been struggling with this one for quite a while and cannot seem to find a solution for this find/replace scenario. Perhaps I'm getting rusty.
I have a file that contains a number of metrics (exactly 3 fields per line) from a few appliances that are collected in parallel. To identify the appliance the metrics belong to, there's a header (the name of the asset basically) that is printed just once before all the rest of the text.
What I want to do is find the appliance name and print it before each one of the metrics. See below:
Sample input:
Expected output:
The ending file should, therefore, contain lines with 4 fields each one. Any clues or pointers would be appreciated.
I am trying to get a total number of tapes w/out headers or footers in a ERV file and append it to the file. For some reason I cannot get it to work. Any ideas?
#!/bin/sh
dat=`date +"%b%d_%Y"`
+ date +%b%d_%Y
dat=Nov16_2006

So, I have a file that has some duplicate lines. The file has a header line that I would like to keep at the top.
I could do this by extracting the header from the file, 'sort -u' the remaining lines, and recombine them. But they are quite big, so if there is a way to do it with a single... (1 Reply)
Hi All,
I need to BCP out a table into a text file along with the table headers. Normal BCP out command only bulk copies the data, and not the headers.

srand
rand(3C)rand(3C)NAME
rand(), rand_r(), srand() - simple random-number generator
SYNOPSIS DESCRIPTION
uses a multiplicative, congruential, random-number generator with period 2^32 that returns successive pseudo-random numbers in the range
from 0 to 2^15-1.
can be called at any time to reset the random-number generator to a random starting point. The generator is initially seeded with a value
of 1.
returns a random number at the address pointed to by the randval parameter. The seed parameter can be set at any time to start the random-
number generator at an arbitrary point.
Note
The spectral properties of leave a great deal to be desired. provides a much better, though more elaborate, random-number generator (see
drand48(3C)).
RETURN VALUE
If seed or randval is NULL, returns 0. Otherwise, returns a psuedo-random integer.
EXAMPLES
The following:
int x, y;
srand(10);
x = rand();
y = rand();
would produce the same results as:
int x, y, s = 10;
x=rand_r(&s);
y=rand_r(&s);
WARNINGS
Users of should note that rand_r() now conforms with POSIX.1c. The old prototype of is supported for compatibility with existing DCE
applications only.
