Hi All,
I have a quary regarding grep command in linux.
I have a file which contains
56677
56677
+56677
+56677
56677
56677

I want to extract total count of "56677"
When I hit the following command
#cat filename | grep -w -c '56677'
the result comes 7. Its counting... (3 Replies)
I'm trying to find a exact word match but couldn't do it.
ABC
ABC_NE
Searching for ABC_NE tried
grep -w </ABC_NE/>
grep "^ABC_NE$"
but didn't worked , any awk variants would also help.

I have a file that has the words I want to find in other files (but lets say I just want to find my words in a single file). Those words are IDs, so if my word is ZZZ4, outputs like aaZZZ4, ZZZ4bb, aaZZZ4bb, ZZ4, ZZZ, ZyZ4, ZZZ4.8 (or anything like that) WON'T BE USEFUL.
I need the whole word... (6 Replies)
QUESTION1:
How do you grep only an exact string. I am using Solaris10 and do not have any GNU products installed.

Hi All,
I have a text / log file which contains strings like meta777, 77, meta, 777. Now I want to write a script which can detect a string 'meta#777' in a text file & number of occurence of 'meta', number of #, number 7, 77, 777.
I'm using grep -e '77' filename but no luck. It is returning... (5 Replies)

Hi
I am trying to grep multiple exact word from log file and directing it to a new file.
however my log file has many numeric values, such as 0400, 0401, 0404
and all html error also starts with 404, 401 etc
so I just want to grep only when 404, 401 etc is coming, NOT 0400, OR 0401
i have... (8 Replies)

combinatorics
math::combinatorics(n) Tcl Math Library math::combinatorics(n)
__________________________________________________________________________________________________________________________________________________NAME
math::combinatorics - Combinatorial functions in the Tcl Math Library
SYNOPSIS
package require Tcl 8.2
package require math ?1.2.3?
::math::ln_Gamma z
::math::factorial x
::math::choose n k
::math::Beta z w
_________________________________________________________________DESCRIPTION
The math package contains implementations of several functions useful in combinatorial problems.
COMMANDS
::math::ln_Gamma z
Returns the natural logarithm of the Gamma function for the argument z.
The Gamma function is defined as the improper integral from zero to positive infinity of
t**(x-1)*exp(-t) dt
The approximation used in the Tcl Math Library is from Lanczos, ISIAM J. Numerical Analysis, series B, volume 1, p. 86. For "x >
1", the absolute error of the result is claimed to be smaller than 5.5*10**-10 -- that is, the resulting value of Gamma when
exp( ln_Gamma( x) )
is computed is expected to be precise to better than nine significant figures.
::math::factorial x
Returns the factorial of the argument x.
For integer x, 0 <= x <= 12, an exact integer result is returned.
For integer x, 13 <= x <= 21, an exact floating-point result is returned on machines with IEEE floating point.
For integer x, 22 <= x <= 170, the result is exact to 1 ULP.
For real x, x >= 0, the result is approximated by computing Gamma(x+1) using the ::math::ln_Gamma function, and the result is
expected to be precise to better than nine significant figures.
It is an error to present x <= -1 or x > 170, or a value of x that is not numeric.
::math::choose n k
Returns the binomial coefficient C(n, k)
C(n,k) = n! / k! (n-k)!
If both parameters are integers and the result fits in 32 bits, the result is rounded to an integer.
Integer results are exact up to at least n = 34. Floating point results are precise to better than nine significant figures.
::math::Beta z w
Returns the Beta function of the parameters z and w.
Beta(z,w) = Beta(w,z) = Gamma(z) * Gamma(w) / Gamma(z+w)
Results are returned as a floating point number precise to better than nine significant digits provided that w and z are both at
least 1.
