You can't pass awk variables to the shell directly. You could use an intermediate file or a (named) pipe, or you can use command substitution
or process substitution in bash/ksh93/zsh
--
or a regular pipe in ksh and zsh only
(also works with bash 4 with shopt -s lastpipe in a non-interactive shell)

Heyas
Figured me had a 'typo' in tui-conf-set, i went to fix it.
Now, i also figured, it might be nice to have tui-conf-set report (to console, not only exit code) wether it could save the variable to the file or not.
This said, I appended this code: (the tui-title and tui-echo lines are... (3 Replies)

shells
shells(4) File Formats shells(4)NAME
shells - shell database
SYNOPSIS
/etc/shells
DESCRIPTION
The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.
A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by the routines
which search the file. Blank lines are also ignored.
The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh,
/bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh,
/usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list.
Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1).
