The following script generate all abbrevations for a string :
Code:
$ cat gen_abbrev.ksh
#!/usr/bin/ksh

echo "$1" | \
nawk -v Abbrev_Len=${2:-6} '

function SplitString(str       ,i ,slen) {
    slen = length(str);
    for (i=1; i<=slen; i++)
        string_array[i] = substr(str, i, 1);
    string_array[0] = slen;
    return slen
}

function buildAbbrev(len, abbrev   ,i ,lstr, char) {
    lstr = string_array[0];
#print "buildAbbrev len=" len, "abbrev=[" abbrev "]", "lstr=" lstr;
    if (len > 0 ) {
       for (i=1; i<=lstr; i++) {
           char = string_array[i];
           if (char) {
               string_array[i] = ""
               buildAbbrev(len-1, abbrev char);
               string_array[i] = char;
           }
       }
    } else {
        print abbrev;
    }
    return
}

function buildAllAbbrevs(str, labbrev    ,astr) {
    string_array[0] = 0;
    if (SplitString(str) > labbrev) {
        buildAbbrev(labbrev, "");
    } else print "ERR";
}

{
    buildAllAbbrevs($0, Abbrev_Len);
    exit;
}
'

Example:
Code:
$ ./gen_abbrev.ksh abcd 3
abc
abd
acb
acd
adb
adc
bac
bad
bca
bcd
bda
bdc
cab
cad
cba
cbd
cda
cdb
dab
dac
dba
dbc
dca
dcb
$

You can use it like that :
Code:
gen_abbrev.ksh ${string} 6 |
while read abbreviation
do
     if valid_abbreviation 
     then
         use_abbrevation
         break
     fi
done
