General :: Alias To Run A Program In The Background?
Mar 4, 2011
I'm running Utorrent server and I figure I would create an alias to launch the program and run it in the background.alias utorrent='/home/user1/software/utorrent-server-3.0/utserver &'It seems to run the program but the associated webui program is flaky and won't start correctly.If I manually go to the specified path and run the command ./utserver & , I never seem to have an issue with the webui.I was wondering if this could possibly have anything to do with using the '&' ampersand operator in an alias.

I wonder how one can, if at all, run an X program in the background *in an emulator sub-shell process*. What I mean is to launch a program in an emulator, e.g, by xterm -e gedit
but with gedit (in this example) running in the background from inside the xterm sub-process, so that the xterm will accept other commands. In the above, gedit will run in the foreground, and of course, if you do
xterm -e gedit &
then xterm will run in the background, not gedit.In short, I would like to achieve the same thing as "gedit &" as you manually do in xterm, but from another shell. What I aim to do is write an X init script to achieve this result (to have the emulator open and a program or two running from it, in the background, at the X startup).

I frequently run teamviewer on my netbook because it's my favorite remote desktop application, but it doesn't have an option to run at startup nor hidden. This is what I need:o be able to run teamviewer automatically at startup, hidden as a "service?" (meaning no taskbar button nor tray icon) and with a delay of 20 seconds (it has to be started after my wifi has automatically connected, not before).Can't be so hard, but I don't seem to be able to find a good answer to this in Google.

I think my title pretty much explains it. I am writing a script and I want to start a program in the background, and when that program finishes I want to check the return value to make sure there was no error.For example normal I would do something like this:
#!/bin/sh
program
if [ ! $? -eq 0 ]; then
echo "There was an error"
exit 1
fi
Now I want to do something like this:
#!/bin/sh
PRTN=`program1 &`
program2
if [ ! $? -eq 0 ]; then
[code]....
In this case if program2 finishes before program1, I don't think the return value from program1 $PRTN would be valid at the time it is checked.

I have a script that calls another program/script, xxx, to run in the background. Supposedly this program at most should finish within five (5) minutes so after five (5) minutes, I run some other steps to run the script into completion. My problem is sometimes the program takes longer than five (5) minutes and this is causing problems when running the rest of the steps in the scripts. Can anyone suggest how to re-program my script. At the moment, the KSH script, i.e. test.ksh, is doing as below:
test.ksh:
.....
.....
xxx/xxx.ksh <--- program/script called by the script
sleep 300
..... run the rest of the script .....
..... problem is sometimes xxx/xxx.ksh takes longer than 300 seconds .....
..... any way that I can monitor that xxx/xxx.ksh finishes before I run .....
..... the rest of the scripts .....

I'm trying to figure out how to continue execution of a Python program while a background task is going on.
In bash, it is adding "&" to the end as in:
Code:
#! /bin/bash
find / -iname "*.py" > /tmp/all_pys &
echo "looking for all python scripts and putting them in /tmp/all_pys"
(yes, I know I could just put the echo BEFORE the find but I just use it for example)
Say I do that in python (not necessarily running the shell, but perhaps using scriptutil.ffind or something similar), but want to allow the user to be doing something else while running that search in the background, how would I thread, fork, subprocess (not to be confused with the module and Popen) [or whatever I should call it] that?

I'm a big book lover so I read a lot. On windows I used Alreader for it's incredible handyness & it had a smooth lite brown background color. So it was easier for my eyes to read books in rtf, txt & so on formats instead of the default white background which is very annoying. Can you please suggest me a software like that for linux?

I am going through and old .cshrc file and it contains the following alias:
alias pwd 'echo $cwd'
I used to think that this is how pwd might have been implemented. But looks like thats not the case (because then this alias is meaningless).

I was trying to add new alias "alias ls='ls --color=auto'" in .profile, but it never worked I displayed all the alias that are current available and did not see the one I just added and found this among them:
lsls $LS_OPTIONS
and the LS_OPTIONS is "-N --color=none -T 0"
this is in /etc/csh.cshrc file which I do not have permission to edit.
Is there way to overwrite it?
Also I do not see a .cshrc under my home directory. Can I just make one and source it? Or do I have to link it to some source file that already exists?

I would like to use something like a 'cdl' alias that would cd into the directory i choose and then ls the contents automatically. I find myself using ls after i cd into a directory all the time. Something like:
alias='cdl=cd $1;ls'
usage: cdl /local/dir

I'm testing out the aliases to have a better understanding on how to shorten commands. I am trying to list all files whose file names end with a .c extension in which starts from the current working directory and recursing through subdirectories as well. And I want to delay the path name expansion until the alias is executed. I want to use the directory /usr/share. Would the command be: alias findc='find -type d -exec /usr/share'?

I have an alias that I would like to use both as a regular user and as root, via sudo. Specifically, it is this:
alias rm=trash This works fine as a normal user, and it works fine when I use sudo -i to get a root shell prompt, but if I use sudo rm, the alias does not apply. So where do I need to put my alias so that it works in one-off sudo commands?

I need to occasionally touch a file with the current timestamp as the filename. I would do so this way:
touch `date "+%Y-%m-%d_%H-%M"`.txt
However, I'd like to define an alias for this. When I try adding to the bashrc this:
alias td="touch `date "+%Y-%m-%d_%H-%M"`.txt"
the result is that the filename is the same during the entire session, since the `date ..` gets calculated just once during login...
How can I get the command to expand only when I call the alias? Or must I use a function for this?

I have packer installed for AUR packages, but I want to be able to use the pacman command for both. I think I will need a function for this -- what I mean is that whenever I use pacman, it will try using packer and if that fails (invalid option) it will use pacman-color. It could also decide which program to use based on the arguments. I can't just use packer (alias pacman='sudo packer') because packer doesn't have some options like -R to remove packages. I want to always use it to install and upgrade packages however, because It can install from the default repositories as well as AUR.
Does someone know how to accomplish this, or could point me in the right direction? I'm new to bash scripting. error (e.g. pacman -V prints packer: Option '-V' is not valid.).

I would like to create several aliases to eth0, but have the addresses assigned by DHCP instead of being set to static IP's. Is this even possible? All the examples I've seen assign a static IP using the command:

When at the command line, I find that I have to type out this command very often: find . -iname "*php" -exec grep -H query {} ; I'd love to set up an alias, script, or shortcut to make it work easier. I would like to do something like: mysearch query ("*php") (.) It would be great if the command could accept three arguments, in reverse order:
query string, file name expression, directory If the second two arguments were omitted they would default to not being included, and the current directory. Finally, the icing on the cake would be that if additional variables were included (4th, 5th, 6th...) they would be injected as additional arguments for the find command (like I could say -type d) at the end. Attempted code I tried the example below, but I'm still having trouble setting default values. What am I doing wrong?
#!/bin/bash
c=${param1+.}
b=${param2+*}
a=${param3+test}
find $c -iname $b -exec grep -H $a {} ;

I know that using alias I can run a whole command with a shortcut. But my requirement is to use parts of a long command and in between I have to pass some user defined values.
E.g. Suppose I have to routinely copy a directory to another remote directory on a remote machine.The remote machine name is quite long as well as the directory path to which I want to copy the files into.So the command to do scp would look like this[URL]Now I want to do some sort of aliasing (say "ecp") so that I just need to pass the source_directory name and the ecp command and do my job

I'm trying to setup an alias, that when I change to another directory, any directory, it will also display all its contents like ls -al:Well, that doesn't work. I guess it's an issue with the use of wild-cards.Maybe I should define a new, so far unused, name for the alias like cdl for example.Would be great if someone could help me. I search in several examples for bash aliases but couldn't find the right solution.

I have a program which mounts /dev/sdb1 for which I lack the source code. This device does not exist on my RedHat 9 system and I want to create /dev/sdb1 such that it's an alias for /dev/hdb1 Can I do this? with MAKEDEV?
I need to have an alias which will allow it to mount, not create a symbolic link to an already mounted directory. i.e. 'mount /dev/sdb1 /mnt/harddrive' should actually mount /dev/hdb1

I successfully edited the .bashrc file to get ruby version manager (rvm) working. Now I would like to turn that setting into an alias so that if i type the word 'ruby' into the terminal it not only goes to the rvm settup but also defaults to my webdev folder which is in my user home directory and also exicutes a command that will open up gedit ready to be used as the text editor for editing the .rb files. Can this be done i would settle for some added code for the 'if then' statement: so far it looks like this:
[Code]...
I don't want to mess with the default setup on this system too much and think things could get out of hand if i am not careful. So am cautious about doing anything at this stage. I wonder if it is possibel thought to setup that whole 'if then' statement as an 'alias'. I read a few referances to alias and looked in the manual like any good newby should but am needing your help please. getting out of the MSwindows mind set and into the linux logic is not so easy but is a great experience
