[cross-posted on bug-bash@gnu.org (gmane.comp.shells.bash.bugs) and
help-b...@gnu.org]
Hello
I have
GNU bash, version 3.2.25(1)-release (x86_64-redhat-linux-gnu) on an
up-to-date CentOS 5.7 (Final) x64,
and
GNU bash, version 4.1.10(4)-release (i686-pc-cygwin) on Windows 7 x64
SP1.
In both OSes I noted that `source´ built-in does not work on a FIFO. On
CentOS the command is just ignored, and on cygwin it blocks indefinitely
(I guess). Ok, cygwin FIFOs may not be a good test case, but I think
CentOS ones are.
Trying the same thing with ksh version
'sh (AT&T Research) 93t+ 2010-02-02',
or with
'tcsh 6.14.00 (Astron) 2005-03-25 (x86_64-unknown-linux) options
wide,nls,dl,al,kan,sm,rh,color,filec',
or
'zsh 4.2.6 (x86_64-redhat-linux-gnu)'
than it works fine.
Here is my test example
[root@appserver2 ~]# mkfifo /tmp/myfifo
[root@appserver2 ~]# echo ls -l >/tmp/myfifo &
[2] 23771
[root@appserver2 ~]# source /tmp/myfifo # no `ls´ output here...
[root@appserver2 ~]# rm /tmp/myfifo
rm: remove fifo `/tmp/myfifo'? y
[2]+ Exit 1 echo ls -l > /tmp/myfifo
[root@appserver2 ~]#
Is it a known problem with bash ? Is it fixed on newer versions ?
Thank you,
Timothy Madden
