With the output from the echo commands you showed us in post #7 in this thread, it appears that the tr and while read loop are behaving as expected. What makes you believe that it is not working correctly?

Note that the script should now work with an input file that contains a list of comma- and/or newline-separated list of hosts. It will not, however, make any attempt to grab only a hostname from an input line like:
Code:
variable=hostname

Are you saying that your script doesn't work if you feed it data from a file in this alternative format?

Note also that if a first line in a shell script starts with a space character followed by #!, that line is NOTHING but a comment; it does not affect what interpreter is used to process that script. #! in a script has absolutely no effect on the running of that script unless those are the 1st two characters in the file. (And, there shouldn't be a space following the #! either.)

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.

ATTRIBUTES

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.
