[Resolved] Any one good at bash scripting?

OhLordy

Hi, I've been working on this little search and replace BASH script for a while now and I can't work it out.

#!/bin/bash
# /gp
for var_name in $(egrep -o '\$[^_][a-z0-9_]{2,20}' ./address_edit_logic1.php | egrep -o '[a-z0-9_]+')
do
echo $var_name
echo "s/\\\$$var_name/\\\$PAGE_VARIABLES['$var_name']/g"
sed -e "s/\$$var_name/\$PAGE_VARIABLES['$var_name']/gp" ./address_edit_logic1.php > buffer
echo $var_name
echo " "
#mv buffer test.dat
done

It's supposed to put all my stray variables into one big array called $PAGE_VARIABLES to make debugging the site easier. The first bit works fine, it pulls out the variable name all fine and dandy and if I run the output of

echo "s/\\\$$var_name/\\\$PAGE_VARIABLES['$var_name']/g"

it works that works fine. However if I just run the script it changes nothing.
Any help would be appreciated.

PS
If anyone knows of any good linux help forums I'd be greatfull. Posted it on JustLinux but others may be helpfull too.

God I'm an idiot,
My boss just came over and pointed out that because the output of sed is going elsewhere only the last execution of sed is being stored ie the buffer file keeps geting overwritten.
