I just noticed that running
. /usr/src/linux/script/ver_linux
prints out strange libc version when I run it
as a normal user. It prints out expected output if
I run it as superuser.
Output Example: Incorrect and correct examples.
Binutils 2.10.0.26
! Linux C Library 1.3.so*
Dynamic linker ldd: version 1.9.11
--- 7,9 ----
Binutils 2.10.0.26
! Linux C Library 2.1.3
Dynamic linker ldd: version 1.9.11
After playing with the ver_linux script,
I found that if the command "ls" is aliased to
"ls -aF", the output is incorrect.
Not that I alias "ls" for superuser, but
I usually write bug report, etc. in
a normal user account, and ls is
aliased to "ls -aF" there.
Here is a potential fix to "ver_script".
(Given the possibility of various shell binaries/shell
startup code setting, etc., I think the
common denomiator solution is to use the output of
which as the name of the ls binary.)
I didn't change the handling of other commands.
"ls" is likely to be aliased, but I wonder
whether other commands are aliased. YMMV.
Possible fix to ver_script is attached.
