# To kill a process gracefully:

# To kill a process forcefully:
kill -9 <pid>

 tldr:kill 
# kill
# Sends a signal to a process, usually related to stopping the process.
# All signals except for SIGKILL and SIGSTOP can be intercepted by the process to perform a clean exit.
# More information: <https://manned.org/kill>.

# Terminate a program using the default SIGTERM (terminate) signal:
kill process_id

# List available signal names (to be used without the `SIG` prefix):
kill -l

# Terminate a background job:
kill %job_id

# Terminate a program using the SIGHUP (hang up) signal. Many daemons will reload instead of terminating:
kill -1|HUP process_id

# Terminate a program using the SIGINT (interrupt) signal. This is typically initiated by the user pressing `Ctrl + C`:
kill -2|INT process_id

# Signal the operating system to immediately terminate a program (which gets no chance to capture the signal):
kill -9|KILL process_id

# Signal the operating system to pause a program until a SIGCONT ("continue") signal is received:
kill -17|STOP process_id

# Send a `SIGUSR1` signal to all processes with the given GID (group id):
kill -SIGUSR1 -group_id
