View 7 RepliesCode: cmd='date | wc'
$cmd If this script is executed, an error is generated. The reason written was that "The execution fails because the pipe is not expanded and is passed to date as an argument".What is meant by expansion of pipe. When we execute date | wc on the command line, it goes fine.then | is not treated as an argument. Why?

I am trying to process a column separated data file, with a few bash command. For example, I have
Code:
file1 aaaa yes
file2 aaaa no
file3 bbbb yes
Let say I want to create new file with the output of first column and do something else with the output of 3rd column. Of course there are many ways to process this data file, but I wish to know by using awk, how could I do it. I'm trying:
Code:
awk '{system("touch $1")}' datafile
but the shell command will not able to get the awk '$1' output. How do I get this done ? And for another question, if the data file contains the variable name of a shell variable, how could I make use of it during a awk output ? For example I have a datafile1:
Code:
server1 yes
server2 no
And in another server declaration data file, I got this datafile2:
Code:
server1=xxx1
server2=yyy1
And in my awk script, I want to achieve something like (the syntax is definitely wrong, just to demonstrate what I assume it will like):

This is weird. I have a shell script with no execute rights.$ chmod -x test.shThen I try$ test.shwhich does not work. (I have "." in PATH)When I do$ . test.shit works! I can run the script even though I have no execute rights. Why is that?Another question: If I have a shell script without a hash bang, I still can execute the shell script. Why? What does hash bang do? If there is no hash bang, why is the shell script run? What does the hash bang do

I have a big bash script ,its goal is to download movie one by one . But I often get into a problem: if this script is executed in cron,it often does not completely download the movie.I often find the movies it downloaded are several KB while the movie is actually 20MB.So I think it is because it did not wait for finishing one task ,and jump to download another.So I want to know ,is there a way to force the bash script to wait until one movie downloaded completely and then start to download another movie ?

Is it possible to allow a group/user to execute a command, where one of the parameters of the command is a group as well? example that does not work as intended:
Code:
Cmnd_alias SU=/bin/su -l %group1 This example works sortof, it treats the "%group1" literally. I know I can list out the "/bin/su -l <eachuser>", but as you can imagine that is impractical. In this example, I want people in group2(not shown for brevity sake) to be able to su to someone in group1

I would like to have an user that can execute al command with sudo.I configured sudo with yast2 and in the sudoers file actually there is a line with:USER ALL = (ALL) ALLWhere user is my username.But I can't use some command like ifconfig becouse it say that it can't find the command. I think that this is becouse of path, but shouldn't i get root path using sudo?
View 3 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).

View 2 Replies View RelatedI am working in a CentOS environment with numerous CentOS machines. Currently there are multiple developers that each have their own login/home directory and then for various admin tasks we all share a single super user account.
The problem
I have a number of aliases, variables, functions, and settings that exist in my personal login's .bash_profile. None of these are available in the shared super user's .bash_profile. My current work around is that everytime I sudo in as the super user and I re-execute my .bash_profile from my personal user's home directory. I am not allowed to edit the init stuff for the super user
The Question
Is there any way I can automate my sudo sequence such that it will execute my personal .bash_profile after I've executed sudo without requiring me to edit the super user's bash init stuff?

View 3 Replies View RelatedI am trying to use a freshly installed kubuntu 10.04.1 LTS and am having major problems with delays in command execution. The box worked fine after installation. I then brought it to the client and it was fine for another day or so. Now, most of the commands I run take up to five minutes to execute. An 'ls' or 'top' will run straight away but and 'ssh','rm' or 'sudo apt-get' will just sit there for ever:
[Code]...
A reboot changed nothing. The shutdown was immediate so 'shutdown' is another command that works properly. The load of the box is '0', I used team viewer to see if I got the same problem from the LAN side rather than the WAN. It's the same. I thought it might have been the disks that had spinned down but it would have sped up after the ssh connection. After further analysis, it looks like this could be an authentication problem. The problem shows once the ssh password is validated and when we use sudo. Could this be related to the installation of samba3?

I was wondering if there was a possibility to execute a series of terminal commands just by double-clicking an icon. For example, there would be an icon on my desktop, and if I were to doubleclick it, it would execute "cd ~/.wine2" and then "WINEPREFIX="$HOME/.wine2" wine program.exe".
