Unable to execute files

Admin32 — Thu, 03 Apr 2003 08:10:32 GMT

Greetings all,

I've got a problem with one Linux Redhat 7 workstation here on our network.

It seems like we are unable to execute any new file placed into the system no matter what user you are logged in as.

For example, I logged in as root in order to install open office and even thought the "install" file is properly flagged as an executable, when running it I get a "permission denided".

The same problem exists when trying to run any other new file I copy to this system.

I'm suspecting the problem has got something to do with the system's shell environment. I tried bash and tcsh and the results were the same.

Any ideas ?

Thanks.

Chris Partsenidis.

hi chris,

can u just write a single script and see if you are able to execute it.

also are there read+ execute permission for the entire directory tree and the file.

Balaji,

I've checked the directory permissions and they are fine, I've even tried chmod 777 but still the same result.

Simple scripts will not execute, same problem arises.

Cheers,

Okies,

Executing the script from its directory gave me the same error, while /bin/bash 'script'

resulted in the proper execution of the script !

hi,

how are you executing the script.

script

or

./script

try the second one. i guess your current directory is not in the path (it should not be for security).

When using ./script to execute it, I get the same error. Its definately not a path problem

/bin/bash script OR
/bin/bash /home/user/script
will work.

hi
tried out what u say. i am unable to reproduce.

./script gives permission denied only when it doesnt have execute permission.

i hope u have checked that already. can u try some other shell , say /bin/sh or /bin/ksh.

Hi,

The problem is that /bin directory is not added to your PATH variable.

#echo $PATH

look for /bin . if it is not there then run this command.

#export $PATH=$PATH:/bin

Edit .bash_profile and add /bin to the PATH variable declaration.

Try executing scripts now.
