I am running a for loop to execute a command to , say 100 hosts, but I don't know how many I have done so far or how many are left
Will it make any sense?
Newbewie,
I'm sorry to say that you're not making any sense to me. You say you're executing a command on a 100 hundred hosts and then your message talks about wanting to number the lines in a file (does that file contain a list of hostnames?). In your original message it looked like you were trying to say something about counting the current line number and the number of words on that line (or something that would involve printing each line prefixed by *two* numbers.
So, I really don't know what you're trying to do. If you just want something like a count down then you could use something like this:
Where this gives you a prevew of which host is about to be contacted with a summary of how many have been done and how many there were, total, when the process first read the file?
Perhaps investing a bit more effort on posting a clear description of what you're trying to do would help.

getopt_long
GETOPTS(3) libbash getopts Library Manual GETOPTS(3)NAME
getopts -- libbash library for command line parameters parsing
SYNOPSIS
$retval getopt_long <Instructions> <Parameters>
DESCRIPTION
This is a documentation for libbash getopts library, that implements getopt_long function for bash(1). For documentation of bash getopts
function, please see getopts(1) ( getopts(1posix) on some systems).
Here is a table for reference:
getopts(1) (or 1posix on some systems) implemented by bash
getopts(3) implemented by libbash.
getopt(1) implemented by getopt utils (part of util-linux)
getopt_long(1) implemented by libbash and installed to section 1 instead of 3 to prevent collision with C man pages.
getopt(3) implemented by GNU C library.
getopt_long(3) implemented by GNU C library.
I have also seen separate getopt utility which part of util-linux package.
The getopt_long function parses the command line arguments. It uses Instructions as the rules for parsing the Parameters.
The Instructions
A string that specifies rules for parameters parsing. The instructions string is built of a group of independent instructions, separated by
a white space. Each instruction must have the following structure:
-<SingleLetter>|--<MultiLetter>-><VariableName>[:]
This structure contains three parts:
-<SingleLetter>
This is the parameter single-letter sign. For example -h.
--<MultiLetter>
This is the parameter's corresponding multi-letter sign. For example --help.
<VariableName>[:]
This is the name of the variable that will contain the parameter value. For example: HELP.
The Variable name can represent one of two variables types:
Flag variable (not followed by ':')
In this case, it will hold the value 1 if 'on' (i.e. was specified on command line) and will not be defined if 'off'.
Value variable (followed by ':')
In this case, the value it will hold is the string that was given as the next parameter in the Parameters string (Separated by
white-space or '=' ). If input contains more then one instance of the considered command line option, an array of the given
parameters will be set as the value of the variable.
The Parameters
The Parameters are simply the parameters you wish to parse.
RETURN VALUE
This function returns a string that contains a set of variables definitions. In order to define the variables, this string should be given
as a parameter to eval function. This value is returned in the variable $retval.
EXAMPLES
Parse command line parameters looking for the flags -h | --help and -v | --version and for the value -p | --path :
getopt_long '-h|--help->HELP
-v|--version->VERSION
-p|--path->PATH:' $*
eval $retval
In this example, for the parameters --help --path=/usr/ the variables that will be created are:
HELP=1
PATH=/usr/
for the parameters --help --path=/usr --path=/bin the variables that will be created are:
HELP=1
PATH=(/usr /bin)
BUGS
Values must not contain the string `__getopts__'. This string will be parsed as a single white-space.
A value should not start with an already defined multi-letter sign. If such a value exists, it will be treated as the equivalent singe-letter
sign. This bug only accures when using a single-letter sign, or a multi-letter sign that are not followed by a `='.
For example: If we have a script named `foo', and we parse the parameters `-d|--dir:' and `-f|--file:', then
foo -d --file
and
foo --dir --file
will not work
foo --dir=--file
will work.
