General :: Ubuntu - Cannot Execute Basic Commands (ps, Ls, Ifconfig) - File Not Found
May 4, 2011
When I try execute a variety of basic commands (including ps, ls, ifconfig, locate), I receive the error 'no such file or directory'.
Here are some suggestions that I've found online, that I have tried without success: I did a 'whereis ps' and found the file in the /bin/, and have checked that '/bin' appears when I do 'echo $PATH' I did a filesystem check which showed my hard drive as being clean I tried doing a 'sudo chmod 777 ps' but was told that I dont have permission. I don't think permissions for these files would have changed though (and I can't check as I can't run the 'ls' command).
My new VPS is running Debian 5.0 (bash 3.2.29), and some commands seems to be missing. For example the ps command is not here, neither is ls (but dir works). Is there a package missing or what's the deal?
i am working on some kind of PBX and i have list of telephone numbers inside a file, i have to insert these numbers into the correct command and then telnet to a remote server and execute these commands. i can read the telephone numbers and insert them into the command with no problem, but when i try to insert these commands into the send i face problem. here is the basic code
i can make external loop inside the Bash which read the input file and issue the command and then telnet and execute, but this will make the script connects and disconnects again for each line which cause high load on that server and hardwar problem. i am wondering if there is an option inside the expect interperter which makes the send read directly from a file... somthing like this:
since a recent upgrade to Mandriva 2010.1 I am not able to 'sudo' as administrator or when I use the 'root' password. I am the only user on this machine (Dell Inspiron 530S multi-booted with Window's Vista Home Premium, Ubuntu 10.4, and Mandriva 2010.1). I can get into the 'Manage Users' section of the control center by authenticating as 'root' but I can't access 'sudoers file' from command line.
