Scripiting quote and variable issues
Hello all I have an interesting problem here that I can't seem to figure out. Note this exists inside a script with the following header: m#!/usr/bin/sh

What I am trying to do is build an automounting script for USB hdd's, the idea is that the user plugs their drive in then runs the script. The script looks at dmesg and seaches for the lines that contain the drive information. From those lines I pull what USB location the drive is attached to, this is where I am having an issue:
Code:
 
 
rsh . -l int "autosu - root -c 'dmesg |grep pci@ |head -1 | cut -d/ -f 4 |cut -d' ' -f 1'"

The problem as far as I can figure is that I have single quotes inside of single quotes (inner marked in red), if I remove that cut statement I get exactly what I expect with the extra stuff on the back end I need to cut off; otherwise it brings in the entire line ignoring both cut statements.

In addition I am also trying to assign that to a variable inside the script something along the lines of this:
Code:
 
USBL='rsh . -l int "autosu - root -c 'dmesg |grep pci@ |head -1 | cut -d/ -f 4 |cut -d' ' -f 1' " '

Can anyone help me ....

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/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/pfcsh,  /usr/bin/pfksh,
       /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list.

       Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)).

FILES

       /etc/shells	       lists shells on system
