I am trying to write a script that reads names from a file called input, removes names if they have the same letter next to each other and prints the others.
e.g. Colin & John would be printed
Garry & Lynn would be removed
My thinking is that I read in each name and break it in to a substring and compare each elements neighbour with itself. If at any point array[i] = array[i+1] the script discards the name and moves on to the next one.
My problem lies with printing the valid names. I have used a nested if statement if [ "$i" == "$((${#s}))" ]; so that once the script has reached the end of a name and it hasn't been discarded it must be valid and therefore should be printed. The script prints nothing and I am at a loss as to why. I would be very grateful if anyone could point out the flaw to me.
Regards,
Colin

osalang
OSALANG(1) BSD General Commands Manual OSALANG(1)NAME
osalang -- information about installed OSA languages
SYNOPSIS
osalang [-dlL]
DESCRIPTION
osalang prints information about installed OSA languages. With no options, it prints an unadorned list of language names to standard output.
These names can be passed to the -l options of osacompile(1) and osascript(1). The options are as follows:
-d Only print the default language.
-l List in long format. For each language, osalang will print its component subtype, manufacturer, and capability flags. There are eight
groups of optional routines that scripting components can support. Each flag is either a letter, meaning the group is supported, or
'-', meaning it is not. The letters map to the following groups:
c compiling scripts.
g getting source data.
x coercing script values.
e manipulating the event create and send functions.
r recording scripts.
v ``convenience'' APIs to execute scripts in one step.
d manipulating dialects.
h using scripts to handle Apple Events.
For descriptions of the groups and the APIs in each of them, see <http://developer.apple.com/documentation/mac/IAC/IAC-361.html>.
-L Same as -l, but also prints the description of each component after its name.
