Description Rene Uittenbogaard 2003-01-09 14:57:40 UTC
Description of problem:

The jobs command output cannot be sent through a pipe.

$ sleep 300 &
[1] 21238
$ jobs
[1]  + running    sleep 300
$ jobs | wc 
      0       0       0


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
$ sleep 300 &
[1] 21238
$ jobs
[1]  + running    sleep 300
$ jobs | wc 
      0       0       0


Actual Results:  'jobs' seems to produce no output when reading from the pipe.

Expected Results:  the pipe reading process should receive the same output as 
is printed on the terminal when just typing 'jobs'

Comment 1 Rene Uittenbogaard 2003-01-09 15:00:32 UTC
produced using zsh-4.0.4-8, but the bug is present in some earlier versions, 
too.

Comment 2 Jens Petersen 2003-02-10 14:01:16 UTC
Still seems to be present in zsh-4.0.6.

Comment 3 Jens Petersen 2003-05-01 01:10:08 UTC
Seems to be ok with zsh-4.0.6.

Comment 4 Rene Uittenbogaard 2003-05-07 09:46:13 UTC
Still doesn't work, even with 4.0.6:

/home/rene: sleep 1000&
[1] 1221
/home/rene: jobs
[1]  + running    sleep 1000
/home/rene: jobs | wc
0       0       0
/home/rene: echo $ZSH_VERSION
4.0.6
/home/rene: rpm -q zsh 
zsh-4.0.6-5




Comment 5 Rene Uittenbogaard 2003-05-07 09:51:58 UTC
Same for 4.0.6-7:

/home/rene: jobs 
[1]  + running    sleep 1000
/home/rene: jobs | wc 
      0       0       0
/home/rene: echo $ZSH_VERSION
4.0.6
/home/rene: rpm -q zsh
zsh-4.0.6-7
      

Comment 6 Jens Petersen 2003-05-07 20:39:53 UTC
Reproduced again :)  Not sure, why I thought it was ok.

Ok, it turns out this is a known problem - see the thread starting with

http://www.zsh.org/mla/users/2002/msg00755.html

and in particular http://www.zsh.org/mla/users/2002/msg00772.html

It seems 4.1 has some workaround for this.
