To disable an account, change the password field in the /etc/passwd file to an asterisk '*' and change the login shell to /bin/false .
and you can schedule it in the crontab
like * 13 * * 1-5 <file name>

lckpwdf
lckpwdf(3C) Standard C Library Functions lckpwdf(3C)
NAME
lckpwdf, ulckpwdf - manipulate shadow password database lock file
SYNOPSIS
#include <shadow.h>
int lckpwdf(void);
int ulckpwdf(void);
DESCRIPTION
The lckpwdf() and ulckpwdf() functions enable modification access to the password databases through the lock file. A process first uses
lckpwdf() to lock the lock file, thereby gaining exclusive rights to modify the /etc/passwd or /etc/shadow password database. See
passwd(4) and shadow(4). Upon completing modifications, a process should release the lock on the lock file using ulckpwdf(). This mechanism
prevents simultaneous modification of the password databases. The lock file, /etc/.pwd.lock, is used to coordinate modification access to
the password databases /etc/passwd and /etc/shadow.
RETURN VALUES
If lckpwdf() is successful in locking the file within 15 seconds, it returns 0. If unsuccessful (for example, /etc/.pwd.lock is already
locked), it returns -1.
If ulckpwdf() is successful in unlocking the file /etc/.pwd.lock, it returns 0. If unsuccessful (for example, /etc/.pwd.lock is already
unlocked), it returns -1.
USAGE
These routines are for internal use only; compatibility is not guaranteed.
FILES
/etc/passwd password database
/etc/shadow shadow password database
/etc/.pwd.lock lock file
