I am trying to execute executable files in bash without adding ./ I know there must be an alias to add in .bashrc, that must be something like alias PATH=$PATH:. But this seems not to be working.
View 1 RepliesWe have a custom app that runs on boot on some older hardware running DSL linux, and their startup manager was quite simple. We purchased some newer Asus eeebox's which run xandros and things are quite stable and run nice with 1 exception.The application only runs from the root (/) location. This box auto logs in as 'user' and there is a /home/user/.kde/Autostart folder where you can stick scripts to run at boot. So I have a start.sh script, and with little bash programming tried things such as;
sudo cd /
sudo /startapp.pl
but the errors start spewing with the basic;can't find data/xyz as it's looking in the local.I thought there was a basic cwd (change working directory) but everything I try just forces the run from that location.Any ideas or suggestions are appreciated, but things like can you change the code, etc. can't be done, so it must be a programming thing. The only other thought I had but not sure, can you do a cronjob with @boot or something, that when the box starts, it can run this job as root and fire off?
I am programming in bash and really stuck finding directory names. I have a script to find all the .php files on my / partition which will return the whole path. Is there a way to print directory hierarchy with all those values leaving out the forward slashes.

Code:
...
BACKUP_TARGET_FILES[2]=/boot/config-* # no problems
BACKUP_TARGET_FILES[3]="/root/random dir with space/file*" # this is the problem
...
then later in the script I want to expand BACKUP_TARGET_FILES elements as below
Code:
IFS_DEFAULT="$IFS"
shopt -s nullglob

IFS=

this code seems to work but I'm not quite satisfied with it. I'd like to get rid those IFS changes, but haven't found out a solution as of yet. Problem with default IFS seems to be that with it neither $pattern or "$pattern" work; it either interprets pattern as multiple words (because of spaces) and so expands to wrong paths or it ignores * because it's within quotes.
I am killing myself with this, please someone come to the rescue...

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 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
This should be a simple thing to accomplish, but I can seem to figure it out. Essentially, I want to have a bash alias or function that will let me recursively grep the current directory. A while back I added this to my .bashrc:
Code:
alias rg="grep -r --exclude=*/.svn/* --exclude=*.swp"
This works fine, (and also ignores any svn and vim swp files), and I can call it like:
Code:
rg foo *
However, 99.999% of the time, I am only interested in searching in the current directory, so the "*" is a bit redundant. Also, I would say 5-10% of the time, I am typing faster than thinking and forget the "*", so grep just sits there trying to read from stdin. It's a pretty minor thing, but ideally I'd like to be able to just type:
Code:
rg foo
I've tried creating a function to handle this:
Code:
function rg(){
grep -r --exclude=*/.svn/* --exclude=*.swp $1 *
}
but it behaves exactly the same as the alias above. escaping the "*" with 's doesn't work, and neither does trying `pwd` (or even a hard-coded path) in its place.

I have program (command line) that requires another program be installed and in its path. So I downloaded the file (.tgz), and extracted. I followed the compile and make instructions and ended up with a folder on my desktop that contains the excutable but is not in the path of the the other program. How can I do this..I think that I have about 20 more .tgz files to do this with.

I have been trying to change my PATH environment variable to no avail. I am using Jessie i386 with MATE. Using my .bashrc file works but not well because with subshells the modifications get repeated. I want the change to occur on login.
I tried modifying ~/.profile ~/.bash_profile /etc/profile and /etc/environment and one or two others but in no case did my change get picked up even after logging out and in again and even after rebooting. I searched the Internet and found each of the above places to make the change but they don't seem to work with Jessie.
Where do I make the necessary change?
Where is the universal PATH variable set/exported in Karmic?It is not exported from the normal place (/etc/profile). I can't find where it is set. I tried Code:find /etc/* | xargs grep "export PATH=" and it did not reveal the magic place.
