Trouble with passing Variable from bash to awk gsub command
Would really appreciate it if someone could point out my mistake in this line of code, i've been staring blankly at it trying everything i can think of some time now and coming up with nothing.
Desired output is to have the script replace "foo" with "bar" in field 2 of FILENAME only on lines beginning with Username entered into read.
After this step the idea is to replace "foo" with ANY data that's in the specified Field, and the Field number to also be specified by the user via a read command.
So if anyone knows a simpler command for doing that all in 1 go that'd be much appreciated too.

apc_add
APC_ADD(3) 1 APC_ADD(3)apc_add - Cache a new variable in the data storeSYNOPSIS
bool apc_add (string $key, mixed $var, [int $ttl])
DESCRIPTION
array apc_add (array $values, [mixed $unused = NULL], [int $ttl])
Caches a variable in the data store, only if it's not already stored.
Note
Unlike many other mechanisms in PHP, variables stored using apc_add(3) will persist between requests (until the value is removed
from the cache).
PARAMETERS
o $key
- Store the variable using this name. $keys are cache-unique, so attempting to use apc_add(3) to store data with a key that
already exists will not overwrite the existing data, and will instead return FALSE. (This is the only difference between
apc_add(3) and apc_store(3).)
o $var
- The variable to store
o $ttl
- Time To Live; store $var in the cache for $ttl seconds. After the $ttl has passed, the stored variable will be expunged from the
cache (on the next request). If no $ttl is supplied (or if the $ttl is 0), the value will persist until it is removed from the
cache manually, or otherwise fails to exist in the cache (clear, restart, etc.).
o $values
- Names in key, variables in value.
RETURN VALUES
Returns TRUE if something has effectively been added into the cache, FALSE otherwise. Second syntax returns array with error keys.
EXAMPLES
Example #1
A apc_add(3) example
<?php
$bar = 'BAR';
apc_add('foo', $bar);
var_dump(apc_fetch('foo'));
echo "
";
$bar = 'NEVER GETS SET';
apc_add('foo', $bar);
var_dump(apc_fetch('foo'));
echo "
";
?>
The above example will output:
string(3) "BAR"
string(3) "BAR"
