Need an explanation

[Davor Bira?]

I have enconture strange behavior on my server.
It is C3600 with HPUX 11.0.
There is file bla:
pwd
/
ll bla
-rwxrwxrwx 1 root sys 12 Apr 12 15:20 bla
more bla
reboot
root

When I try this command, server shutdowns:
bla = $(cat bla)

There is entry in /var/adm/shutdownlog like this:
15:34 Tue Apr 12, 2005. Reboot: (by root)

There is no core file or something in /var/adm/crash.
Any help?

What you do is expected behaviour from bla = $(cat bla)

What do you want??

Hi,

Why should there be a crash file?

you did a reboot

bla=$(cat bla)
bla=reboot
reboot

Yep, you ran "bla" as root I'll bet and rebooted the box. Remove the file "bla".

You may want to look over other files on your server. Wide open perms on home made files could be trouble.

Hi,
maybe you expected that this line should perform a variable assignment, only:
# bla = $(cat bla)
but because of the space after "bla" the shell considers "bla" a separate command to be executed - which it apparently is.

It's not generally a good thing to name variables the same as executables! Also the space before the '=' means that the shell interprets your command as

Run executable bla with arguments '=' and '$(cat bla)'

Your substitution is wrong...

$(cat bla) - should be:

BLA=`cat bla`

Then echo $BLA will be:

reboot
root
