A better way to compare text length percentage?
I have a solution, but it seems labored. I would like to compare strings return a value in percent out of 100.


Such as:

Code:
$ text1='a'; text2='abc'; s1=${#text1}; s2=${#text2}
$ [ "$s1" -gt "$s2" ] && di=$(( (($s1*100) / ($s2+1)) )) || [ "$s2" -gt "$s1" ] && di=$(( (($s2*100) / ($ls+1)) ))
$ echo $di
300

i.e., 'abc' is 300% longer than 'a'


For beginners: s1=${#text1} will return the length of $text1. In this case it would return '1' because it is one character long ('a').


I've looked at the man pages for 'diff' and some others and haven't figured out an easy way that this could be done in a more simple manner; yet, something tells me I'm missing something. I'm repeating the formulas, and I'm wondering if there is perhaps some way to do an inverse of a result... Anyways, it seems redundant.


Ideas?

named.star

named.star(4)						     Kernel Interfaces Manual						     named.star(4)

NAME

       named.star - Defines data used by named to initialize the BIND (Berkeley Internet Name Domain) name server file

SYNOPSIS

       /etc/namedb/named.*

DESCRIPTION

       The  data  files  referenced in the named.conf file can have any names, but they are generally given names of the form /etc/namedb/named.*.
       This naming convention is used for convenience in maintaining the named daemon's file.

       The records in the named data files are called resource records. Except for comments (starting with a ; (semicolon) and continuing  to  the
       end  of the line), the resource records in the data files generally follow the format of the resource records that the named daemon returns
       in response to queries from resolver routines.

       The named.conf file is the default configuration (or boot) file for the named server.  The named daemon reads the start-up  file  when  the
       named daemon starts and when receiving the signal SIGHUP.

EXAMPLES

       The following examples portray two domains on two different networks: Domain abc.aus.osf.com, Internet address 192.9.201.n

       (where n varies for each system on the network)

       Domain xyz.aus.osf.com, Internet address 128.114.100.n

       (where n varies for each system on the network)

	      In  this	sample	configuration, both the primary and the secondary name servers are in the abc.aus.osf.com domain, and host hera is
	      the gateway host.  The following are sample entries in a named.ca file: ; root name servers.
		       1	  IN	NS    relay.osf.com.  relay.osf.com.   3600000	  IN	A     129.114.1.2 The following two files are sam-
	      ple entries from the named.data files for hosts venus and allen.	(The data files can have any name you choose, as long as that name
	      is defined in the named.boot file. In this case, the names are named.abcdata and named.xyzdata.)
