OK, I should provide more info. first I am running in ksh.

I have a file with one line of a series of words that are three letters long, using s space as the delimiter.

I want to run a script which will retrieve those words and assign them to a variable, which i can run with my command in a loop until each word has been used, individually each time in the command until each three letter word has been used.

the file looks like this:

AIN OTB ALK SJA ALS HAH INA (etc..)

I want to run the command with all three letter word individually.

The commands i want to perform is already designed. I just need to insert the words in the command in a loop to do it each tmie. note the file may change with the count of words but it will always be three letter words. therefore it has to count the words each time it is run. i was thinking I would cat the file, pipe it to a wc -w and use that as the count for how many time to perform the loop. (I.e. wordct="cat <filename> | wc -w") with this variable I have a defined count of how many words each time.

I hope this helps.

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a	Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
