# pidlock
Simple PID based locking for cronjobs, UNIX scripts or python programs
### Requirement:
* requires python (>2 or 3)
### Usage:
* Install with pip
```
sudo pip install -U pidlock
```
* Use it from inside python script
```
import time
from pidlock import PIDLock
locker = PIDLock()
with locker.lock('sleepy_script'):
time.sleep(10)
```
* Use it as commandline/cron job
```
# To display help menu
pidlock -h # Or pidlock --help
# Example usage
pidlock -n sleepy_script -c 'sleep 10'
# Same as
pidlock --name sleepy_script --command 'sleep 10'
```
### Customization:
* You can pass PID file location, verbosity, time limit and minimum interval as arguments
```
# Python Usage
locker = PIDLock(lockdir='~/.pidlock', verbose=True)
with locker.lock('sleepy_script', wait=10, mininterval=1):
time.sleep(10)
```
```
# Commandline usage
pidlock -n sleepy_script -c 'sleep 10' -l ~/.pidlock -v -w 10 -m 1
# Same as
pidlock --name sleepy_script --command 'sleep 10' --lockdir ~/.pidlock --verbose --wait 10 --mininterval 1
