digits in string












0















I am validating string with some standards. It should start wih R- and proj_nm as a variable and project_cd as numbers and any desc
i.e, R-${PROJ_NM}-[Numbers]-anything



if [[ $var == "R-"${PROJ_NM}"-"[[:digit:]]"-"* ]] ; then echo "Naming convention is in correct format" else echo "Not in correct format" exit 1 fi


I am getting output as not in correct format.

If you need to have one or more numbers (you said numbers), then you need [[:digit:]][[:digit:]] for two, [[:digit:]][[:digit:]][[:digit:]] for three etc.



if [[ $var == "R-"${PROJ_NM}"-"[[:digit:]][[:digit:]]"-"* ]] ; then 

    echo "Naming convention is in correct format"

else 

    echo "Not in correct format" 

fi


But you can simplify your quotes a little:



if [[ $var == "R-${PROJ_NM}-"[[:digit:]][[:digit:]]"-"* ]] ; then 

    echo "Naming convention is in correct format"

else 

    echo "Not in correct format" 

fi


Alternatively, with newer bash versions, you can use regular expressions:



if [[ $var =~ ^R-${PROJ_NM}-[0-9]+- ]] ; then 

    echo "Naming convention is in correct format"

else 

    echo "Not in correct format" 

fi

            Is this a new Fibonacci Identity?

            Image
            6 1 $begingroup$ I have found the following Fibonacci Identity (and proved it). If $F_n$ denotes the nth Fibonacci Number, we have the following identity begin{equation} F_{n-r+h}F_{n+k+g+1} - F_{n-r+g}F_{n+k+h+1} = (-1)^{n+r+h+1} F_{g-h}F_{k+r+1} end{equation} where $F_1 = F_2 = 1$ , $r leq n$ , $h leq g$ , and $n, g, k in mathbb{N}$ . It is not too hard to show that this identity subsumes Cassini's Identity, Catalan's Identity, Vajda's Idenity, and d'Ocagne's identity to name a few. I have done a pretty thorough literature review, and I have not found anything like this, but I am still wondering if anyone has seen this identity before? I found this by accident after noticing some patterns in some analysis work I was doing, so if this is already known I would be curious to see w...
