Package: bash
Version: 4.1-3
Severity: normal
Hi,
if a program ist started with $($prog) the output is different from <command>
or even $(<command>). Example with find (excluding a directory from search):
$ ls -l /test
total 16
drwxrwxr-x 2 hgb hgb 4096 Nov 6 02:14 a
drwxrwxr-x 2 hgb hgb 4096 Nov 6 02:14 b
drwxrwxr-x 2 hgb hgb 4096 Nov 6 02:14 c
drwxrwxr-x 2 hgb hgb 4096 Nov 6 02:14 d
$ find /test -type d ! -wholename "/test"
/test/c
/test/b
/test/d
/test/a
$ echo "$(find /test -type d ! -wholename "/test")"
/test/c
/test/b
/test/d
/test/a
$ prog='find /test -type d ! -wholename "/test"'
$ echo $prog
find /test -type d ! -wholename "/test"
$ echo "$($prog)"
/test
/test/c
/test/b
/test/d
/test/a
$
As seen above /test ist shown when $prog is executed.
I see the same behavior with
GNU bash, version 3.2.25(1)-release (x86_64-redhat-linux-gnu) (CentOS)
GNU bash, version 3.2.39(1)-release (i486-pc-linux-gnu) (debian)
I understand that the above looks crazy and not like a problem out of real life
.... I had to use find to crawl through a huge tree and remove only a few files
in it. I came across the above problem when feeding an array with the output of
find; I fixed it for now by removing the unwanted entries from the output
array.
Thanks in advance for looking into this.
Regards
