[Bradford] bash hell , removing " from a strings

[Martyn Ranyard]

Hi Dick,

  What I would be tempted to do is something like the following (bear in
mind that with unix there's umpteen million ways to skin a cat) :

#!/bin/bash

select="\"foo\" \"bar\" \"lemon\" \"cheese\""
echo "original is : $select"
count=$(echo $select | sed s/\"//g | wc -w)
echo "count is $count"

for f in $(seq 1 $count); do
  export $(echo $select | sed s/\"//g | cut -f$f -d' ')="\
    $(echo $select | sed s/\"//g | cut -f$f -d' ')"
done

echo $foo
echo $bar
echo $lemon
echo $cheese

which should output :
original is : "foo" "bar" "lemon" "cheese"
count is 4
foo
bar
lemon
cheese

Perhaps not the neatest or most elegant way but it uses tools I'm familiar
with and didn't require much thinking.  Hopefully I've understood the
desired result as well.  Using export may also not be a good thing, but I
remember that echo "value" | read var doesn't set $var, and can't remember
another way around that.

Hope that helps,
