이미 실행 중인 nohup 프로세스에 새 명령을 보내거나 nohup에서 두 명령을 함께/동시에 실행하는 방법은 무엇입니까?

Question

이유는 모르겠지만 여기에서 대안이 작동하지 않는 것 같습니다.tty/stty(터미널)가 아니고 Expect, sshpass가 없을 때 어떻게 명령에 비밀번호를 보내나요?

세 가지 시도가 모두 성공한 것 같습니다.

참조된 sh 스크립트에서 reauth 실행
Python에서 인증 실행
위의 두 가지를 모두 수행하세요.

작업을 실행하는 데 사용하는 샘플 스크립트:

# https://unix.stackexchange.com/questions/724902/how-does-one-send-new-commands-to-run-to-an-already-running-nohup-process-e-g-r
# sh ~/diversity-for-predictive-success-of-meta-learning/main_nohup_snap.sh
# - set up this main sh script
export RUN_PWD=$(pwd)
source ~/.bashrc
source ~/.bash_profile
source ~/.bashrc.user
echo HOME = $HOME
# since snap .bash.user cd's me into HOME at dfs
cd $RUN_PWD
echo RUN_PWD = $RUN_PWD
realpath .

source cuda11.1

conda init bash
conda activate metalearning_gpu

# - get a job id for this tmux session
export SLURM_JOBID=$(python -c "import random;print(random.randint(0, 1_000_000))")
echo SLURM_JOBID = $SLURM_JOBID
export OUT_FILE=$PWD/main.sh.o$SLURM_JOBID
export ERR_FILE=$PWD/main.sh.e$SLURM_JOBID
export WANDB_DIR=$HOME/wandb_dir
echo $OUT_FILE
echo $ERR_FILE

export CUDA_VISIBLE_DEVICES=5
echo CUDA_VISIBLE_DEVICES = $CUDA_VISIBLE_DEVICES
python -c "import torch; print(torch.cuda.get_device_name(0));"

# - CAREFUL, if a job is already running it could do damage to it, rm reauth process, qian doesn't do it so skip it
# top -u brando9
# pkill -9 reauth -u brando9

# - expt python script then inside that python pid attach a reauth process
# should I run rauth within python with subprocess or package both the nohup command and the rauth together in badsh somehow
#python -u ~/diversity-for-predictive-success-of-meta-learning/div_src/diversity_src/experiment_mains/main_sl_with_ddp.py --manual_loads_name sl_hdb1_5cnn_adam_cl_filter_size --filter_size 4 > $OUT_FILE 2> $ERR_FILE &
nohup sh -c 'echo $SU_PASSWORD | /afs/cs/software/bin/reauth; python -u ~/diversity-for-predictive-success-of-meta-learning/div_src/diversity_src/experiment_mains/main_sl_with_ddp.py --manual_loads_name sl_hdb1_5cnn_adam_cl_filter_size --filter_size 4 > $OUT_FILE 2> $ERR_FILE' > $PWD/nohup.out$SLURM_JOBID &
#nohup python -u ~/diversity-for-predictive-success-of-meta-learning/div_src/diversity_src/experiment_mains/main_sl_with_ddp.py --manual_loads_name sl_hdb1_5cnn_adam_cl_filter_size --filter_size 4 > $OUT_FILE 2> $ERR_FILE &

# other option is to run `echo $SU_PASSWORD | /afs/cs/software/bin/reauth` inside of python, right?
export JOB_PID=$!
echo JOB_PID = $JOB_PID
echo SLURM_JOBID = $SLURM_JOBID

# - Done
echo "Done with the dispatching (daemon) sh script"

주요 명령:

nohup sh -c 'echo $SU_PASSWORD | /afs/cs/software/bin/reauth; python -u ~/diversity-for-predictive-success-of-meta-learning/div_src/diversity_src/experiment_mains/main_sl_with_ddp.py --manual_loads_name sl_hdb1_5cnn_adam_cl_filter_size --filter_size 4 > $OUT_FILE 2> $ERR_FILE' > $PWD/nohup.out$SLURM_JOBID &

나는 옵션 3을 계속 사용할 것이라고 생각하므로 둘 다 실행하십시오. 왜냐하면 분산 작업을 실행하는 경우 해당 프로세스가 내 허락 없이 무작위로 종료되는 것을 원하지 않기 때문입니다. 이를 위해 Python 스크립트는 다음을 수행합니다.

def run_bash_command(cmd: str) -> Any:
    import subprocess

    process = subprocess.Popen(cmd.split(), stdout=subprocess.PIPE)
    output, error = process.communicate()
    if error:
        raise Exception(error)
    else:
        return output

def stanford_reauth():

    ref: https://unix.stackexchange.com/questions/724902/how-does-one-send-new-commands-to-run-to-an-already-running-nohup-process-or-run
    """
    reauth_cmd: str = f'echo $SU_PASSWORD | /afs/cs/software/bin/reauth'
    out = run_bash_command(reauth_cmd)
    print('Output of reauth (/afs/cs/software/bin/reauth with password): ')
    print(f'{out=}')

재인증 작업을 자주 확인하는 것을 잊지 마세요.

# - CAREFUL, if a job is already running it could do damage to it, rm reauth process
# pkill -9 reauth -u brando9
