Possible bug in bash

[flyingrhino]

Hi,

Should the "else" condition after the:  ||  run if the last command in 
the:  &&  section exits non zero?

I tested it this way:

Script:


#!/bin/bash

[[ "a" == "a" ]] && \
    {
    echo "equal"
    ls x
    } || {
    echo "***** SHOULD NOT DISPLAY 4"
    }


Result:

./moo.sh
equal
ls: cannot access 'x': No such file or directory
***** SHOULD NOT DISPLAY 4

GNU bash, version 4.4.20(1)-release (x86_64-pc-linux-gnu)



BTW, I've checked other conditions as follows and they look ok:

#!/bin/bash

[[ "a" == "a" ]] && \
    {
    echo "equal"
    ls x
    } || {
    echo "***** SHOULD NOT DISPLAY 4"
    }

echo "================================"


[[ "a" == "a" ]] && \
    {
    echo "equal"
    } || {
    echo "***** SHOULD NOT DISPLAY 1"
    }

echo "================================"

[[ "a" == "a" ]] && \
    {
    echo "equal"
    ls x
    :
    } || {
    echo "***** SHOULD NOT DISPLAY 2"
    }

echo "================================"

[[ "a" == "a" ]] && \
    {
    echo "equal"
    ls x || :
    } || {
    echo "***** SHOULD NOT DISPLAY 3"
    }

echo "================================"

[[ "a" == "b" ]] && \
    {
    echo "equal"
    } || {
    echo "NOT EQUAL"
    }
