複数の環境変数$ VARを含む大きな文字列の評価を他の環境変数にどのように格納できますか？

なぜならnohupコマンドの認証が実行されていることを確認する必要があります。ここで文字列として実行するには、実際のコマンドを入力する必要があります。

nohup sh -c 'echo $SU_PASSWORD | /afs/cs/software/bin/reauth; python -u $RUN_CMD' > $PWD/nohup.out$SLURM_JOBID &

$RUN_CMD文字列を生成し、次の変数に保存してみました。

export RUN_CMD='${!HOME}/diversity-for-predictive-success-of-meta-learning/div_src/diversity_src/experiment_mains/main_diversity_with_task2vec.py --manual_loads_name diversity_ala_task2vec_delauny > $OUT_FILE 2> $ERR_FILE'

しかし、私はそれを動作させることはできません。どうすればいいですか？私の試み：

(metalearning_gpu) brando9~ $ export RUN_CMD='${!HOME}/diversity-for-predictive-success-of-meta-learning/div_src/diversity_src/experiment_mains/main_diversity_with_task2vec.py --manual_loads_name diversity_ala_task2vec_delauny > $OUT_FILE 2> $ERR_FILE'
(metalearning_gpu) brando9~ $ echo $RUN_CMD
${!HOME}/diversity-for-predictive-success-of-meta-learning/div_src/diversity_src/experiment_mains/main_diversity_with_task2vec.py --manual_loads_name diversity_ala_task2vec_delauny > $OUT_FILE 2> $ERR_FILE

(metalearning_gpu) brando9~ $ export RUN_CMD=$(echo '$HOME/diversity-for-predictive-success-of-meta-learning/div_src/diversity_src/experiment_mains/main_diversity_with_task2vec.py --manual_loads_name diversity_ala_task2vec_delauny > $OUT_FILE 2> $ERR_FILE')
(metalearning_gpu) brando9~ $ echo $RUN_CMD
$HOME/diversity-for-predictive-success-of-meta-learning/div_src/diversity_src/experiment_mains/main_diversity_with_task2vec.py --manual_loads_name diversity_ala_task2vec_delauny > $OUT_FILE 2> $ERR_FILE

(metalearning_gpu) brando9~ $ export RUN_CMD=$(echo '${!HOME}/diversity-for-predictive-success-of-meta-learning/div_src/diversity_src/experiment_mains/main_diversity_with_task2vec.py --manual_loads_name diversity_ala_task2vec_delauny > $OUT_FILE 2> $ERR_FILE')
(metalearning_gpu) brando9~ $ echo $RUN_CMD
${!HOME}/diversity-for-predictive-success-of-meta-learning/div_src/diversity_src/experiment_mains/main_diversity_with_task2vec.py --manual_loads_name diversity_ala_task2vec_delauny > $OUT_FILE 2> $ERR_FILE

(metalearning_gpu) brando9~ $ export RUN_CMD=(eval '$HOME/diversity-for-predictive-success-of-meta-learning/div_src/diversity_src/experiment_mains/main_diversity_with_task2vec.py --manual_loads_name diversity_ala_task2vec_delauny > $OUT_FILE 2> $ERR_FILE')
(metalearning_gpu) brando9~ $ echo $RUN_CMD
eval
