uname output: CYGWIN_NT-5.1 tom 1.5.19(0.150/4/2) 2006-01-20 13:28 i686 Cygwin
Machine Type: i686-pc-cygwin
Bash Version: 3.1
Patch Level: 17
Release Status: release
Description:
All these work fine:
cat <~/.bash_history
cat <(cat ~/.bash_history)
while read f; do echo $f; done <~/.bash_history
But, this fails:
while read f; do echo $f; done <(cat ~/.bash_history)
bash: syntax error near unexpected token `<(cat ~/.bash_history)
This is important when the operations in the loop need to affect
the current shell environment (as contrasted with a | pipe)
Also duplicated error on linux bash 3.00.16(1)-release
(i386-redhat-linux-gnu)
Repeat-By:
See description.
