Bash Version: 3.1
Patch Level: 17
Release Status: release

Description:
unexpected execution of incomplete (and currently syntactically 
invalid?)
commandline by tab-completion subsystem


The problem is the completion system's attempt to run the directory
portion of the filename to be completed through the set of shell word
expansions.  It's not appropriate to perform command substitution in
that case.  This will be fixed for the next bash version.

Repeat-By:

[EMAIL PROTECTED]:~$ declare -a NAME[0]="Andres" NAME[1]="Sajo"
[EMAIL PROTECTED]:~$ declare -p NAME
declare -a NAME='([0]="Andres" [1]="Sajo")'

## Command 1
[EMAIL PROTECTED]:~$ echo ${ NAME[0]}
bash: ${ NAME[0]}: bad substitution

##Command 2
[EMAIL PROTECTED]:~$ echo ${NAME[0] }
Andres
##Should have reported the previous error

[EMAIL PROTECTED]:~$ echo ${NAME[0]}
Andres

## The "bad substitution error" should be OR in both Commands OR in
none of them.

Fix:
None

bash does not jump where it is supposed to jump

2008-01-18 Thread William Tambe 

Please read the comments on the code below.
I don't know but is it really how bash was supposed to run?

The code below should only print end



[ "test" = "test" ] && {
# after the false command bash should jump directly to echo end
# but instead run echo echo "test != test"
false
} || {
echo "test != test"
}

echo end
