Bug #1397

Updated by tuxillo over 2 years ago

Salute. 

 

 The jobs(1) utility gives different output when called from a script and when 
 
 from an interactive shell. 

 <pre> 
 

 [beket@voyager ~] cat testjobs.sh 
 
 #!/bin/sh 
 
 sleep 30 & 
 
 jobs -l 
 
 [beket@voyager ~] sh testjobs.sh  
  
 [1] + 10005 Running            
            
 [beket@voyager ~] sleep 30 & 
 
 [1] 10006 
 
 [beket@voyager ~] jobs -l 
 
 [1]+ 10006 Running                   sleep 30 & 
 
 [beket@voyager ~]  
 </pre> 

  

 It is not clear whether the jobs(1) should work at all inside a script. POSIX 
 
 says that since it doesn't fall into the 'special' built-in category a new 
 
 environment (subshell?) would be created upon its invocation. Even this is true, 
 
 the jobs aren't specific to the shell environment, so they should be visible to 
 
 jobs(1). And in any case, the command should either print nothing or print all 
 
 the fields. 

 

 NetBSD 5.0: 
 <pre> 
 
 $ sh testjobs.sh  
  
 [1] + 27159 Running             sleep 30 
 </pre> 

 

 SunOS 5.10: 
 <pre> 
 
 tuxillo@solaris$ /usr/xpg4/bin/sh testjobs.sh  
  
 [1] + 11754        Running                   <command unknown> 
 </pre> 

 

 FreeBSD: same as us. (kindly reported by vstemen at #dragonflybsd). 

 

 Any thoughts ? 

 

 Best regards,
