環境路徑 - 終端OSX

Question

我可以運行Java，而無需直接在終端發出命令-classpath但只要我嘗試做在cron它拋出這個錯誤：

Usage: java [-options] class [args...] 
      (to execute a class) 
    or java [-options] -jar jarfile [args...] 
      (to execute a jar file) 

where options include: 
    -d32   use a 32-bit data model if available 
    -d64   use a 64-bit data model if available (implies -server, only for x86_64) 
    -client  to select the "client" VM 
    -server  to select the "server" VM 
    -jvm   is a synonym for the "client" VM [deprecated] 
    -hotspot  is a synonym for the "client" VM [deprecated] 
        The default VM is client. 

    -cp <class search path of directories and zip/jar files> 
    -classpath <class search path of directories and zip/jar files> 
        A : separated list of directories, JAR archives, 
        and ZIP archives to search for class files. 
    -D<name>=<value> 
        set a system property 
    -verbose[:class|gc|jni] 
        enable verbose output` 

研究已經告訴我，這可能是一個環境路徑問題？如何知道使用終端vs cron時我的路徑是什麼？

我envoking的java權從cron，crontab的是一樣的東西：

0 3 * * * *的java -classpath /Users/tb582/Desktop/sample1.jar:/Users/tb582 .... ..

只指定整個路徑在cron：

型 「的Java」

應該類似這樣的東西輸出：

/usr/bin/java
