View 1 RepliesI an a relative linux newbie who just installed ubuntu 9.10 workstation (I have enstalled around 4 times on viurtual machines but generally do nothing with Ubuntu other than get Apache, MySql and php going) and was able to do most of want I wanted with the initial user (user1) using sudo.
It was painful however to work with Nautilis and Gedit, because everything i tried to do said I did not have the permissions.
I then added my user (the initial user) to group root. Nautilis and Gedit then allowed me to easily edit files (I only used to verify I COULD edit files - I did NOTactually edit any)
I then rebooted my computer and since then I cannot so anything with sudo. I get a message "user1 is not in the sudoers file". If I do groups user1 I can see user1 is listed as a member of user1 and root. However, Nautilis and Gedit respond with no permission to everything again.
I also cannot su to root because it says invalid password (I had not originally set a password for root but it will not accept leaving password blank and now it will not let me sudo to create a password).
what I need to do to make user1 work with sudo again?
whether I should encounter a problem relating to output redirection when using sed from a shell script which is ran by apache? I have given apache privileges in sudoers to run the shell script and the commands within it. However the problem is that when I check auth.log all commands are listed except the sed ones, yet if I run the shell script directly from the command line they work fine and are logged.
So although I realise I probably have some permission issues to solve, I think its strange how sed commands are not being logged at all. would also appreciate any advice on apache and sudoers, am I playing with fire here? Im on lucid 10.04 server
I need to kill a process which has been started by user2 if I am user1 without being sudoers or using root.Do you know if there is a way of setting that when launching the process? Such as a list of users allowed to kill the process?

View 4 Replies View RelatedMy .jar file needs and uses some files in the same directory it's in (everything, including the jar was unzipped into said directory). It runs perfectly when I do java -jar file.jar in the command line, but there's trouble when I double-click the file when running from the file system manager. I've tried a custom command under properties ie java -jar, but the problem is that the .jar file doesn't seem to be able to use any of the files in the same directory. When running, the jar can't find any of the files that it needs.

View 5 Replies View RelatedI want a quick and simple way to execute a command whenever a file changes. I want something very simple, something I will leave running on a terminal and close it whenever I'm finished working with that file. Currently, I'm using this: while read; do ./myfile.py ; done And then I need to go to that terminal and press Enter, whenever I save that file on my editor. What I want is something like this: while sleep_until_file_has_changed myfile.py ; do ./myfile.py ; done
Or any other solution as easy as that. BTW: I'm using Vim, and I know I can add an autocommand to run something on BufWrite, but this is not the kind of solution I want now. Update: I want something simple, discardable if possible. What's more, I want something to run in a terminal because I want to see the program output (I want to see error messages).
