I am writing a bash script to automate the installation of web environment on a base install of Fedora. And I'm at the limit of my last nerve and my bash skills. My brain is screaming at me: "Give up and use perl", but I am trying to stick to bash since the script will modify the perl environment as it runs.
My challenge, or at least my current one, is illustrated in the following code:
Code:
function exec_cmd {
# code removed for sanity checking and loging
local CMD="$1"
local OUT
OUT=`$CMD >> $LOG 2>&1`
# code removed for logging and tracking
return 0
}
for i in Xfce 'Development Libraries' 'Development Tools'
'MySQL Database' 'Perl Development' 'XFCE Software Development'
do
CMD="$YUM -y groupinstall $i"
exec_cmd "$CMD"
done
The code works fine on the first interation through the for loop since Xfce does not contain a space; however, when it reaches 'Development Libraries' and the subsequent multi-word itmes in the list, by the time it gets to executing in exec_sum, 'Development Libraries' is parsed as two separate words. Grrrr
I have tried every quoting approach that I can think of to make this work and all fail, one way or another.
Any help that you can lend will be greatly appreciated!!
Sorry, no go either. Once function exec_cum a multi-word gets parsed to '"Development' 'Libraries"'

Thanks to all of you who are trying to help.
The following is a small test that you can run on your system, as long as it has yum installed, to replicate my problem and test your recommendation. Instead of performing a groupinstall, it will just list information about the group when working
Code:
#!/bin/bash -x
function exec_cmd {
local CMD="$1"
local OUT
OUT=`$CMD`
return 0
}
for i in Xfce 'Development Libraries' 'Development Tools'
do
CMD="yum groupinfo \"$i\""
exec_cmd "$CMD"
done
