[SOLVED] Code does not run when assigned to a variable
I am more of a newbie, but wanted to post this in this forum as I was afraid no one would look at it in unix forums as it concerns shell scripting. I have a shell script that now runs fine with the exclusion of one line:
x=`su nbadmin -c "ssh -t servery /usr/openv/netbackup/bin/bplist -C servery -t 19 -l -R -s 11/01/2012 -e 11/01/2012 /vol/root/"`;echo "$x"This command will run and ssh to the server. It prints out /vol/root after it sshs to servery. However, it does not print out a list of the contents of /vol/root. However, if I run the command WITHOUT assigning it to a variable, like this:
su nbadmin -c "ssh -t servery /usr/openv/netbackup/bin/bplist -C servery -t 19 -l -R -s 11/01/2012 -e 11/01/2012 /vol/root/"It runs and prints all the directories under root. What is it about this command that you cannot assign it to a variable and it won't print out the contents? The bplist -l -R options are supposed to do that and they do so long as I do not assign the command to a variable and echo it.
Any help would be welcome from you gurus!

How do I evaluate the result of a command assigned to a variable??

rc will be the result of the assignment rather than cmd since it executes after. How do I evaluate the result of the command itself?

atf-sh
ATF-SH(1) BSD General Commands Manual ATF-SH(1)
NAME
atf-sh [-s shell] -- interpreter for shell-based test programs
SYNOPSIS
atf-sh script
DESCRIPTION
atf-sh is an interpreter that runs the test program given in script after loading the atf-sh(3) library.
atf-sh is not a real interpreter though: it is just a wrapper around the system-wide shell defined by ATF_SHELL. atf-sh executes the inter-
preter, loads the atf-sh(3) library and then runs the script. You must consider atf-sh to be a POSIX shell by default and thus should not
use any non-standard extensions.
The following options are available:
-s shell Specifies the shell to use instead of the value provided by ATF_SHELL.
ENVIRONMENT
ATF_LIBEXECDIR Overrides the builtin directory where atf-sh is located. Should not be overridden other than for testing purposes.
ATF_PKGDATADIR Overrides the builtin directory where libatf-sh.subr is located. Should not be overridden other than for testing purposes.
ATF_SHELL Path to the system shell to be used in the generated scripts. Scripts must not rely on this variable being set to select a
specific interpreter.
EXAMPLES
Scripts using atf-sh(3) should start with:
#! /usr/bin/env atf-sh
Alternatively, if you want to explicitly choose a shell interpreter, you cannot rely on env(1) to find atf-sh. Instead, you have to hardcode
the path to atf-sh in the script and then use the -s option afterwards as a single parameter:
#! /path/to/bin/atf-sh -s/bin/bash
ENVIRONMENT
ATF_SHELL Path to the system shell to be used in the generated scripts.
