Hello Everybody,
Does anyone know what the @ symbol means in a csh script, if used with a variable assignment as below
@ line = 1
why not just use....
set line=1
Many thanks

Hi All,
I have a little awk script which uses a variable (x):
awk -v x=0 'NF != 6 { ++x } END { print "This batch had " x " errors out of ", NR" records"}'
But when I've tried to put the command in a file I can't seem to declare the variable. I've managed to simplify the code so that I... (4 Replies)
Guys,
Could you please help me out. I need two values in two variables using awk from the o/p of grep.
example:-
grep sdosanjh <filename>
sdosanjh myhostname myfilename
NOW WHAT I WANT IS :-
sdosanjh should be in variable (say NAME)
myhostname should be in variable (say... (8 Replies)
Hi,
In AIX I have a variable with , (coma) separated values assigned to it like shown below
var1=apple,boy,chris
i want to convert this to
var1='apple','boy','chris'
the number of values assigned to var1 might change and it could be from 1 to n
any suggestions please? (3 Replies)
Hi There,
I am writing a ksh script which assigns variable values from file "A" and passes that variables to file "B". While passing the parameters an additional "$" sign is being assigned to awk -v option.
Could any one help me with this please.

So, in awk, I've always put my variable assignments inside of the curly braces, just like dad, and grandpa, and the 26 generations before them. But today I came upon an awk statement that had them outside the braces-- blasphemy!
Seriously, though, is there any practical difference? I was... (3 Replies)
Hi,
Was hoping someone could help with the following:
while read line; do pntadm -P $line | awk '{if (( $2 == 00 && $1 != 00 ) || ( $2 == 04 )) print $3,$5}'; done < /tmp/subnet_list
Anyone know if it is possible to assign $3 and $5 to separate variables within the {} brackets?
Thanks... (14 Replies)
Heyas
Me try to print only the value of a (specific) variable assignment from a file.

bup-margin(1) General Commands Manual bup-margin(1)NAME
bup-margin - figure out your deduplication safety margin
SYNOPSIS
bup margin [options...]
DESCRIPTION
bup margin iterates through all objects in your bup repository, calculating the largest number of prefix bits shared between any two
entries. This number, n, identifies the longest subset of SHA-1 you could use and still encounter a collision between your object ids.
For example, one system that was tested had a collection of 11 million objects (70 GB), and bup margin returned 45. That means a 46-bit
hash would be sufficient to avoid all collisions among that set of objects; each object in that repository could be uniquely identified by
its first 46 bits.
The number of bits needed seems to increase by about 1 or 2 for every doubling of the number of objects. Since SHA-1 hashes have 160 bits,
that leaves 115 bits of margin. Of course, because SHA-1 hashes are essentially random, it's theoretically possible to use many more bits
with far fewer objects.
If you're paranoid about the possibility of SHA-1 collisions, you can monitor your repository by running bup margin occasionally to see if
you're getting dangerously close to 160 bits.
OPTIONS --predict
Guess the offset into each index file where a particular object will appear, and report the maximum deviation of the correct answer
from the guess. This is potentially useful for tuning an interpolation search algorithm.
--ignore-midx
don't use .midx files, use only .idx files. This is only really useful when used with --predict.
EXAMPLE
$ bup margin
Reading indexes: 100.00% (1612581/1612581), done.
40
40 matching prefix bits
1.94 bits per doubling
120 bits (61.86 doublings) remaining
4.19338e+18 times larger is possible
Everyone on earth could have 625878182 data sets
like yours, all in one repository, and we would
expect 1 object collision.
$ bup margin --predict
PackIdxList: using 1 index.
Reading indexes: 100.00% (1612581/1612581), done.
