setting dynamic variable in a function

[tekinept]

Sure this is just some basic scripting 101 snafu, but I'm at a loss.

I am basically building a library, and this piece if becoming a real pain--

function get_current_space () {
echo $*
for check_space in $*
do
check_var=`echo $check_space | sed 's/\//\_/g'`
part$check_var=`df -h | grep "$check_space" | grep -v "$check_space"[a-zA-Z0-9] | awk '{print $1}'`
size$check_var=`df -h | grep "$check_space" | grep -v "$check_space"[a-zA-Z0-9] | awk '{print $2}'`
used$check_var=`df -h | grep "$check_space" | grep -v "$check_space"[a-zA-Z0-9] | awk '{print $3}'`
avai$check_var=`df -h | grep "$check_space" | grep -v "$check_space"[a-zA-Z0-9] | awk '{print $4}'`
perc$check_var=`df -h | grep "$check_space" | grep -v "$check_space"[a-zA-Z0-9] | awk '{print $5}'`
moun$check_var=`df -h | grep "$check_space" | grep -v "$check_space"[a-zA-Z0-9] | awk '{print $6}'`
done

}


this is the output from calling the function with just /boot

mytest.sh: line 7: part_boot=/dev/sda1: No such file or directory
mytest.sh: line 8: size_boot=251M: command not found
mytest.sh: line 9: used_boot=16M: command not found
mytest.sh: line 10: avai_boot=223M: command not found
mytest.sh: line 11: perc_boot=7%: command not found
mytest.sh: line 12: moun_boot=/boot: No such file or directory

I can drop set in front of the variables, and that makes it a variable, but of course won't pass the variable back.

Any help?

In your shell man page pay attention to the eval builtin command.

Hope This Helps, PH.

Yep, that did the trick. Still wondering why it interpreted as a command rather than a var.... Guessing it has to do with the why I am assigning it...
