I want to use find to locate files with two different extensions, and run a grep on the results. The closest I have gotten is incredibly slow and ugly:
for i in `ls -laR|egrep -e '(.js|.css)'`; do find . -name $i -print|xargs grep -H searchBg; done;
This method makes my eyes bleed. Help! ;)

I have one file which first line is blank and second line has some data.
$cat filename
output:
30-MAY-07
I want to store 30-MAY-07 value in one variable.
for that I wrote
var="`head -2 filename`"
It will give that result but I want to truncate the first line which is blank.
plz help. (2 Replies)
I am trying to concatenate 2 files, but before concatenation, I would like to strip off the final character from the first file.
The final character is a form feed (ascii 012 / hex 0C) and there will be an unknown number of these characters in the file. It is only the very last one which I want... (1 Reply)
I posted this already in another thread, but was told that I should create a seperate thread for the following question:
How do I strip the extension when the delimiter might occur multiple times in the filename?
For example:
I have 2 files as input for my script.

Friends
I want to automat sending a letter to different persons whose directories are named as 001, 002, 003, 004.
To push the same letter to all these directories, I need to name the letter as letter.001, letter.002 like that.
Is there any method whereby I get the extension of this letter... (2 Replies)
I copied some files to another folder, and I want to change them from .doc extensions to .txt extensions. I tried using the cp and mv commands, but it didn't work. Is it possible to change file extensions with these commands, and if so how do I do it? I tried using the * wildcard (say cp *.doc... (1 Reply)
Hello all.
I would like to make a script (or two shell scripts) that will do the following.
I need the maximum file name and directory name to be 38 characters long.
As well, if shortening the file name ends up making all of the files in that directory have the same name, then I would like... (9 Replies)

Here is a simplified example of my problem. Say I have the following 3 sub-directories;
./folder1
A.txt
A.sh
./folder2
B.txt
./folder3
C.txt
C.sh
I would like to list the directory names which contain both '.txt' & '.sh' type extensions. I have came up with the following code;... (8 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
