and I want to copy all files except 3: exclude 000po.k, 166po.k,168po.k
I know the long way around it copying these files, but am looking for a shorter way of doing this:

In Perl I can write a condition that evaluates a match expression like this:
if ($foo =~ /^bar/) {
do blah blah blah
}
How do I write this in shell? What I need to know is what operator do I use? The '=~' doesn't seem to fit. I've tried different operators, I browsed the man page for... (3 Replies)
Hi,
I need to match up some numbers in one file to the closest numbers in other file and produce an output file.
File one (f1.txt) is laid out like this

I have a bash script that I want to certain actions if it finds a string in the filenames, and another action if it does not match the string in the filename. Both my individual 'for' statements work on their own, however when i put it all together it returns 'unexpected end of file error'. Can... (3 Replies)
I'm trying to convert this working bash script into an Ash script,
read -p "Username:" _username

However, Ash does not recognize the "=~" character.
How can I do this?
Also, is there a good reference guide, so I... (5 Replies)
I need to check the condition of a variable before the script continues and it needs to match a specific pattern such as EPS-03-0 or PDF-02-1.
The first part is a 3 or 4 letter string followed by a hyphen, then a 01,02 or 03 followed by a hyphen then a 0 or a 1.
I know I could check for every... (4 Replies)
In the bash below the user selects the file to be used. The digits of each file are unique and used to automatically locate the next file to be used in the process. The problem I can not seem to fix is that the full path needs to be referenced in the second portion and it is not currently. Is... (7 Replies)
The bash executes but returns no results and the set -xv showed while the $run variable in blue, was extracted correctly, the $match value in green, was not, rather both values in home/cmccabe/Desktop/f1 were extracted not just the matching.
There will always be an exact match from the $run to... (7 Replies)

num
Num(3) OCaml library Num(3)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. Raise Failure num_of_string if the given string is not a valid representation of an integer
=== 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
