But you are demonstrating bash constructs, particularly the string redirection, <<<.


You also need to quote each element of the python array:
Code:
$ python <<< "print ' '.join(['u/tmp/file.js', 'u/var/test.txt', 'u/tmp/llo.rft'])"
u/tmp/file.js u/var/test.txt u/tmp/llo.rft

Do you really need to pass this python-style array into your script? Can you pass just a comma-delimited string?
Alternatively:
Code:
printf "Parameter 1: %s\n" "$1"
MYARRAY=`echo "$1" | sed 's/^\[//;s\]$//'`
oldIFS="$IFS"
IFS=,
for a in $MYARRAY
do printf "Printing Array: %s\n" "$a"
done
IFS="$oldIFS"

Assuming AIX has the printf utility.

open

OPEN(1) 							     Linux 1.x								   OPEN(1)

NAME

       open - start a program on a new virtual terminal (VT).

SYNOPSIS

       open [-c vtnumber] [-s] [-u] [-l] [-v] [--] command command_options

DESCRIPTION

       open will find the first available VT, and run on it the given command with the given command options, standard input, output and error are
       directed to that terminal. The current search path ($PATH) is used to find the requested command. If no command is specified then the envi-
       ronment variable $SHELL is used.

   OPTIONS
       -c vtnumber
	      Use the given VT number and not the first available. Note you must have write access to the supplied VT for this to work.

       -s     Switch to the new VT when starting the command. The VT of the new command will be made the new current VT.

       -u     Figure out the owner of the current VT, and run login as that user.  Suitable to be called by init. Shouldn't be used with -c or -l.

       -l     Make the command a login shell. A - is prepended to the name of the command to be executed.

       -v     Be a bit more verbose.

       -w     wait for command to complete. If -w and -s are used together then open will switch back to the controlling terminal when the command
	      completes.

       --     end of options to open.

NOTE

       If open is compiled with a POSIX (Gnu) getopt() and you wish to set options to the command to be run, then  you	must  supply  the  end	of
       options -- flag before the command.

EXAMPLES

       open can be used to start a shell on the next free VT, by using the command:

       open bash

       To start the shell as a login shell, use:

       open -l bash

       To get a long listing you must supply the -- separator:

       open -- ls -l
