So close...
This script stripped out the period (.) in the extension when setting ext and when setting base, but puts it back in the printf format string. It also strips out the vee (v) when setting num and when setting base, but it doesn't put it back. I think the first argument to printf in this script needs to be changed from '%s%04d.%s' to '%sv%04d.%s'.

I'm trying to do a script that will look for a log file if it is already there change the name to another name.
I.E
if log.0 is there
rename to log.1
rename log.1 to log.2
rename log.2 to log.3 and so on.
Only thing is I got no idea where or what is the best command to use for this? ... (3 Replies)
hello i'm trying to figure out how to number a blank line. For instance this :
sed '/./=' file | sed '/./N; s/\n/ /'
gives me
1 aaaa
2 bbbbbb
4 cccccc
5 ffkkkfff
6 ffsdfdfs
I would like something like this:
1 aaaaa
2
3 bbbbbb
4
5 cccccc
And so... (6 Replies)
Hello everyone,
I want get numbered lines from a file. and i can do it with: sed = file.txt | sed "/./N; s/\n/ /" | sed -n "5,7p"
but the output that i get is something similar to:
5 line5
6 line6
7 line7
and i want something like this (with 2points after the number):

Hi,
I have this large file and sometimes there are duplicates and I want to basically find them and figure how many there are.
So I have a file with multiple columns and the last column (9) has the duplicates.
eg.
yan

man
ban
tan
tub

let says, i have this number as 000002080, i want to add 1 to make it 000002081, and then i want to add 1 to 000002082, add 1 to 000002083, 84.
i=000002080
TOT=$(echo "scale=9; $i + 1" | bc)
echo $TOT
it shows 2081, i want to retain 000002081, 000002082, 000002082, 000002084. (2 Replies)
Hi,
All I need to do is number a file.
The file looks like this

I'm not really sure how to explain this but I will try. In the attached file if $4=$4 and $5="-" then the last record is 1 and the one above that is 2, etc...
However, $4=$4 and $5="-" then the first record is 1 and the one below that is 2, etc...
"-" example:
chr10 90694830 90695123... (7 Replies)

num
Num(3o) OCaml library Num(3o)NAME
Num - Operation on arbitrary-precision numbers.
Module
Module Num
Documentation
Module Num
: sig end
Operation on arbitrary-precision numbers.
Numbers (type num ) are arbitrary-precision rational numbers, plus the special elements 1/0 (infinity) and 0/0 (undefined).
type num =
| Int of int
| Big_int of Big_int.big_int
| Ratio of Ratio.ratio
The type of numbers.
=== Arithmetic operations ===
val (+/) : num -> num -> num
Same as Num.add_num .
val add_num : num -> num -> num
Addition
val minus_num : num -> num
Unary negation.
val (-/) : num -> num -> num
Same as Num.sub_num .
val sub_num : num -> num -> num
Subtraction
val ( */ ) : num -> num -> num
Same as Num.mult_num .
val mult_num : num -> num -> num
Multiplication
val square_num : num -> num
Squaring
val (//) : num -> num -> num
Same as Num.div_num .
val div_num : num -> num -> num
Division
val quo_num : num -> num -> num
Euclidean division: quotient.
val mod_num : num -> num -> num
Euclidean division: remainder.
val ( **/ ) : num -> num -> num
Same as Num.power_num .
val power_num : num -> num -> num
Exponentiation
val abs_num : num -> num
Absolute value.
val succ_num : num -> num
succ n is n+1
val pred_num : num -> num
pred n is n-1
val incr_num : num Pervasives.ref -> unit
incr r is r:=!r+1 , where r is a reference to a number.
val decr_num : num Pervasives.ref -> unit
decr r is r:=!r-1 , where r is a reference to a number.
val is_integer_num : num -> bool
Test if a number is an integer
=== The four following functions approximate a number by an integer : ===
val integer_num : num -> num
integer_num n returns the integer closest to n . In case of ties, rounds towards zero.
val floor_num : num -> num
floor_num n returns the largest integer smaller or equal to n .
val round_num : num -> num
round_num n returns the integer closest to n . In case of ties, rounds off zero.
val ceiling_num : num -> num
ceiling_num n returns the smallest integer bigger or equal to n .
val sign_num : num -> int
Return -1 , 0 or 1 according to the sign of the argument.
=== Comparisons between numbers ===
val (=/) : num -> num -> bool
val (</) : num -> num -> bool
val (>/) : num -> num -> bool
val (<=/) : num -> num -> bool
val (>=/) : num -> num -> bool
val (<>/) : num -> num -> bool
val eq_num : num -> num -> bool
val lt_num : num -> num -> bool
val le_num : num -> num -> bool
val gt_num : num -> num -> bool
val ge_num : num -> num -> bool
val compare_num : num -> num -> int
Return -1 , 0 or 1 if the first argument is less than, equal to, or greater than the second argument.
val max_num : num -> num -> num
Return the greater of the two arguments.
val min_num : num -> num -> num
Return the smaller of the two arguments.
=== Coercions with strings ===
val string_of_num : num -> string
Convert a number to a string, using fractional notation.
val approx_num_fix : int -> num -> string
See Num.approx_num_exp .
val approx_num_exp : int -> num -> string
Approximate a number by a decimal. The first argument is the required precision. The second argument is the number to approximate.
Num.approx_num_fix uses decimal notation; the first argument is the number of digits after the decimal point. approx_num_exp uses scien-
tific (exponential) notation; the first argument is the number of digits in the mantissa.
val num_of_string : string -> num
Convert a string to a number.
=== Coercions between numerical types ===
val int_of_num : num -> int
val num_of_int : int -> num
val nat_of_num : num -> Nat.nat
val num_of_nat : Nat.nat -> num
val num_of_big_int : Big_int.big_int -> num
val big_int_of_num : num -> Big_int.big_int
val ratio_of_num : num -> Ratio.ratio
val num_of_ratio : Ratio.ratio -> num
val float_of_num : num -> float
