To create a series of bash scripts (step-01.sh to step-10.sh) that depend on the success of previous steps, and ensure each step only runs if its predecessor has completed successfully, you can implement a structure like the one you described. Here’s a breakdown of how to approach this:

1. Structure Overview

• step-01.sh: Initializes environment variables and functions. It checks if the previous steps (step-02.sh to step-10.sh) were successful. If any of those have failed, the script starts from the failed one.
• step-02.sh to step-10.sh: Each script will perform a specific task, and each will check the success of the previous step before running.
• Logging: Use a log file or status files to track success/failure of each step.

2. Design Approach

Create a status file for each step: Each step will write a success or failure status to a corresponding file (e.g., step-01.status, step-02.status, etc.). Check the status of previous steps: Each script will check the status files before proceeding. Environment setup in step-01.sh: This script should set up any necessary environment variables and functions. Sequential Execution: If any step fails, subsequent steps should not be executed. If any previous step fails, the script should start from the failed step. 3. Example Implementation step-01.sh (Initial Setup) bash コードをコピーする #!/bin/bash

Step-01: Setup environment variables and functions

echo "Setting up environment variables..."

Example environment variables (customize as needed)

export MY_VAR="some_value" export ANOTHER_VAR="another_value"

Create a log/status file for step-01

touch step-01.status

Check if all the previous steps (step-02.sh to step-10.sh) have completed successfully

for i in {2..10}; do if [[ ! -f "step-${i}.status" || ! $(cat "step-${i}.status") == "SUCCESS" ]]; then echo "Step ${i} has not completed successfully. Aborting." exit 1 fi done

Everything is okay, marking step-01 as completed

echo "SUCCESS" > step-01.status echo "Step 1 completed successfully." step-02.sh (Sample Step) bash コードをコピーする #!/bin/bash

Step-02: Example task

echo "Executing Step 2..."

Check if step-01 completed successfully

if [[ ! -f "step-01.status" || ! $(cat "step-01.status") == "SUCCESS" ]]; then echo "Step 1 did not complete successfully. Aborting step-02." exit 1 fi

Perform the actual work for step-02

(Insert your actual task here, for example, copying files, processing data, etc.)

echo "Performing the task for step 2..."

If successful, mark step-02 as completed

echo "SUCCESS" > step-02.status echo "Step 2 completed successfully." step-03.sh to step-10.sh Each subsequent script (step-03.sh to step-10.sh) would follow the same pattern as step-02.sh. Here’s an example for step-03.sh:

bash コードをコピーする #!/bin/bash

Step-03: Example task

echo "Executing Step 3..."

Check if step-02 completed successfully

if [[ ! -f "step-02.status" || ! $(cat "step-02.status") == "SUCCESS" ]]; then echo "Step 2 did not complete successfully. Aborting step-03." exit 1 fi

Perform the actual work for step-03

(Insert your actual task here)

echo "Performing the task for step 3..."

If successful, mark step-03 as completed

echo "SUCCESS" > step-03.status echo "Step 3 completed successfully." Repeat this pattern for step-04.sh to step-10.sh.

Final Notes Checking Success/Failure: Each script checks the corresponding status file (step-01.status, step-02.status, etc.). If the status is not SUCCESS, the script exits with an error code (exit 1). Environment Setup: The environment variables and functions should be initialized in step-01.sh, and you can call them in the later steps if needed. Logging: The step-XX.status file will be used to track whether each step was successful (SUCCESS), or you can set it to FAILED if something goes wrong. 4. Running the Scripts To run the scripts, you would typically run step-01.sh first, and it will manage the execution of subsequent steps.

bash コードをコピーする bash step-01.sh bash step-02.sh bash step-03.sh ... bash step-10.sh Or, you can create a master script run_all_steps.sh to run everything in sequence:

bash コードをコピーする #!/bin/bash

for i in {1..10}; do bash "step-${i}.sh" if [[ $? -ne 0 ]]; then echo "Step ${i} failed. Exiting..." exit 1 fi done

echo "All steps completed successfully." 5. Conclusion By organizing each step with checks for previous step success and using status files, you ensure that the process runs sequentially, and only the failed steps will be retried. This approach keeps the process modular and allows easy tracking of progress.
