Package: bash
Version: 3.1dfsg-8
Severity: normal
The bash man page says that the unary -a behaves like -e:
-a file
True if file exists.
-e file
True if file exists.
But I get:
[EMAIL PROTECTED]:~$ touch exists
[EMAIL PROTECTED]:~$ [ ! -e exists ] || echo found
found
[EMAIL PROTECTED]:~$ [ ! -a exists ] || echo found
[EMAIL PROTECTED]:~$
However the following forms work as expected:
[EMAIL PROTECTED]:~$ [[ ! -e exists ]] || echo found
found
[EMAIL PROTECTED]:~$ [[ ! -a exists ]] || echo found
found
[EMAIL PROTECTED]:~$ [ -e exists ] && echo found
found
[EMAIL PROTECTED]:~$ [ -a exists ] && echo found
found
[EMAIL PROTECTED]:~$
Note: I don't think it is a good idea to use the non-standard unary -a
with [, but this is a bug anyway.
