Large password lock script
I am trying to create a script that will take a very large, tab delimited file and then lock accounts.
File headers look like this
id desc server pass sudo lock
test Test user server01 67 no no
"Test user" is under the desc column
Basically if pass column is greater than 60 and lock is no, I need it to ssh to the server in the server column field and lock the account in the id field.
I know i need to use if and awk but I am stumped and running short on time.
Also this needs to be in ksh
Thanks

LEARN ABOUT PHP
wincache_lock
WINCACHE_LOCK(3) 1 WINCACHE_LOCK(3)
wincache_lock - Acquires an exclusive lock on a given key
SYNOPSIS
bool wincache_lock (string $key, [bool $isglobal = false])
DESCRIPTION
Obtains an exclusive lock on a given key. The execution of the current script will be blocked until the lock can be obtained. Once the
lock is obtained, the other scripts that try to request the lock by using the same key will be blocked, until the current script releases
the lock by using wincache_unlock(3).
Warning
Using of the wincache_lock(3) and wincache_unlock(3) can cause deadlocks when executing PHP scripts in a multi-process environment
like FastCGI. Do not use these functions unless you are absolutely sure you need to use them. For the majority of the operations on
the user cache it is not necessary to use these functions.
PARAMETERS
o $key
- Name of the key in the cache to get the lock on.
o $isglobal
- Controls whether the scope of the lock is system-wide or local. Local locks are scoped to the application pool in IIS FastCGI
case or to all php processes that have the same parent process identifier.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
Using wincache_lock(3)
<?php
$fp = fopen("/tmp/lock.txt", "r+");
if (wincache_lock("lock_txt_lock")) { // do an exclusive lock
ftruncate($fp, 0); // truncate file
fwrite($fp, "Write something here
");
wincache_unlock("lock_txt_lock"); // release the lock
} else {
echo "Couldn't get the lock!";
}
fclose($fp);
?>
