I am looking for a bash command that counts the number of times a character appears in a file. For example "I am a newbie, trying to learn shell script". Then the command counts the number of e and gives them as 4. Also I want one that counts the number of times a character in a string is replaced.... (2 Replies)
I've been looking on the internet, and haven't found anything simple enough to use in my code. All I want to do is count how many times "-" occurs in a string of characters (as a package name). It seems it should be very simple, and shouldn't require more than one line to accomplish.
And this is... (2 Replies)

Hi,
I had another question. I was wondering if there was a way to tab a line a variable number of times in tcsh. To go into details, I want to tab a line by how deep a file is in its path.
So here is an example code:
set filea=/blah1/blah2/blah3
set fileb=/blah1/blah2/blah3/blah4

Hello, I am reading the K & R C book, and trying to understand more about putchar()/getchar() by practice. Similar to the exercise 1-12, I want try to parse each line by character. Although there are many site about the exercise, but I could find similar case of mine, which is similar to fold... (11 Replies)
I have kind of a strange one here. I have a file of consecutive /24 ip blocks. If there are 8 consecutive ip blocks which represent a /20 then I need to print the first line. I played around and did not get the results I need, especially when considering that the highest $3 will be is 255 and then... (6 Replies)

Hi
I want to use awk to match where field 3 contains a number within string - then print the line and just the number as a new field.

primes
factor(1) General Commands Manual factor(1)NAME
factor, primes - factor a number, generate large primes
SYNOPSIS
[number]
[start[stop]]
DESCRIPTION
If no arguments are provided on the command line, waits for a number to be typed in. If a positive number is typed, it factors the number
and print its prime factors; each one is printed the proper number of times. It then waits for another number. exits if it encounters a
zero or any non-numeric character.
If an argument is provided on the command line, factors the number as above, then exits.
Maximum time to factor is proportional to sqrt(n) and occurs when n is prime or the square of a prime.
The largest number that can be dealt with by is 1.0e14.
prints prime numbers between a lower and upper bound. If no arguments are provided on the command line, waits for two numbers to be typed
in. The first number is interpreted as the lower bound; the second as the upper bound. All prime numbers in the resulting inclusive range
are printed.
If start is specified, all primes greater than or equal to start are printed. If both start and stop are given, all primes occurring in
the inclusive range start through stop are printed.
start and stop values must be integers represented as long integers.
If the stop value is omitted in either case, runs either until overflow occurs or until it is stopped by typing the interrupt character.
The largest number that can be dealt with by is 2,147,483,647.
DIAGNOSTICS
Both commands print when the input is out of range, illegal characters are encountered, or when start is greater than stop.
EXAMPLES
Print the prime factorization for the number 12:
Print all prime numbers between 0 and 20:
