腳本調用後Bash不會繼續？

Question

我有兩個bash腳本。一個運行完全正常，直到它接到另一個腳本的調用，然後執行該腳本，但永遠不會在原始腳本中繼續，我不知道該如何解決該問題。

此腳本在特定目錄的每個文件夾中運行測試。每個子文件夾都包含一個phpunit.xml文件，當我們輸入每個文件夾時，我們運行composer install和phpunit。

如果目錄是Loader，Routes或Loop，我們將輸入它們並在該目錄下運行腳本。

讓我們看看run-tests腳本：

#!/usr/bin/env bash 

set -e 

function run_tests() { 
    if [[ -f "composer.json" ]] && [[ -f "phpunit.xml" ]]; then 
    if [[ -d "vendor" ]]; then 
     composer update 
     phpunit > /dev/null 
     phpunit 
     cd ../ 
    else 
     composer install 
     phpunit > /dev/null 
     phpunit 
     cd ../ 
    fi 
    else 
    cd ../ 
    fi 
} 

for f in *; do 
    if [[ -d $f ]]; then 
    if [[ $f != ".git" ]] && [[ $f != "bin" ]] && [[ $f != "docs" ]]; then 
     cd "$f/" 

     if [[ $f == "Loader" ]]; then 
     if [[ -d "Assets" ]]; then 
      cd Assets/ 
      chmod +x asset-test 
      ./asset-test 
     fi 
     fi 

     if [[ $f == "Loop" ]]; then 
     cd Loop/ 
     chmod +x loop-test 
     ./loop-test 
     cd ../ 
     fi 

     if [[ $f == "Routes" ]]; then 
     cd Routes/ 
     chmod +x routes-test 
     ./routes-test 
     cd ../ 
     fi 

     run_tests 
    fi 
    fi 
done 

# Go Home. 
cd /vagrant/Freya/ 

## Clean up time! 
## Remove all vendor and composer.lock folders - just because. 
for f in *; do 
    if [[ -d $f ]]; then 
    if [[ $f != ".git" ]] && [[ $f != "bin" ]] && [[ $f != "docs" ]]; then 
     cd "$f/" 
     rm -rf vendor composer.lock 
     cd ../ 
    fi 
    fi 
done 

我們可以看到，一旦它進入檢查，看看如果我們在該目錄是「循環」，那麼，我們是否有一個名爲目錄「資產「裏面。假設此通過，我們就輸入一個目錄，然後運行下一個腳本：

#!/usr/bin/env bash 

set -e 

# Run Composer Install if vendor doesnt exist. 
if [[ -d "vendor" ]]; then 
    composer update 
else 
    composer install 
fi 

# Move up to the root directories and then get wordpress 
cd ../../../ 

# Determine if the trunk is checked out and if we have a wp-test-config.php 
# If not we need to create both or one or the other then run the tests. 
# 
# We run phpunit twice because the second time is when it actually runs. 
if [[ -d "trunk" ]]; then 
    cd "trunk/" 
    if [[ -f "wp-tests-config.php" ]]; then 
    cd ../Freya/Loader/Assets 
    phpunit > /dev/null 
    phpunit 
    else 
    cd ../Freya/Loader/Assets 
    cp wp-tests-config.php ../../trunk/ 
    phpunit > /dev/null 
    phpunit 
    fi 
else 
    sudo svn co http://develop.svn.wordpress.org/trunk/ 
    cd Freya/Loader/Assets 
    cp wp-tests-config.php ../../trunk/ 
    phpunit > /dev/null 
    phpunit 
fi 

的問題是，一旦這個劇本完成後，我張貼的第一腳本的其餘部分NEVER繼續。它就像死在這裏一樣。我需要的是「父」腳本完成，它應退出Loader/Assets並繼續下一個檢查。但事實並非如此。該腳本剛剛存在。

爲什麼？

注：中，第二腳本，我們可以假設它進入第一個嵌套的if語句，它會檢查，在一個wp-tests-config.php主幹目錄我們可以假設，因爲下面的輸出，這是從捕獲的這運行一個腳本：

我們可以在這裏看到兩個問題：

• 的/vagrant/Freya/Loader/Assets/被運行兩次。
• 它從來沒有繼續在第一個腳本。

Answer 1

如果沒有在您的機器上設置任何設置，就很難遠程調試它。要獲得更多有用的答案，可以先嚐試通過連續禁用部分代碼來隔離問題。我可以看到，在你的情況下這可能很難。

這裏僅僅是一些想法進行調試：

• 兩個腳本與set -e運行，即他們將退出的第一個命令（包括第二腳本）與非零退出代碼終止。嘗試添加set -x以查看最後執行的命令。
• 你有很多相對的cd調用。嘗試到pwd就在上一步中確定的最後一個命令之前 - 您可能只是在錯誤的目錄中。
