%groupName ALL = (ALL) NOPASSWD: /bin/bash /path/to/shfile.sh argument1 argument2
argument1 needs to be a url : http://subdomain1.subdomain2.domain.com
argument2 needs to be a path of the form /var/www/demo/SomeFolder/application/config/config.php

If there is a command I can use to find specific file types? Say if I want to find all the jpg's in my home folder, but they don't have the .jpg extension in the name, how would I do it? Or can I set some kind of size parameter to find them? The ones I want are all from my digicam and roughly the same size.

I want to delete all files within a specific folder without actually deleting the folder, what is a good bash command for this?. I found this one but encountered some errors even though I am executing it within the specific folder:
useratdebian:/home/user/folder# find . -type f -exec rm -rf {} ;
[1] 5052
useratdebian:/home/user/folder# find: missing argument to `-exec'
[1]+ Exit 1 find . -type f -exec rm -rf
The command as it appears is:
find . -type f -exec rm -rf {} ;
how to delete only the files contained within the folder called "folder" for example?

View 5 Replies View RelatedI have a requirement to print images (two to be precise) from the command line of a given size and without losing too much quality.
So, I may have two images, a.jpg and b.jpg which may be 4x4" and 6x4" respectively (the sizes may vary). I need to be able to print both these on a single sheet of paper (one under the other) at a given size for each - so a may be 2x2" and b may be 3x2" - the aspect ratio will always be maintained (or as near as possible!)
I am currently doing this a very messy way (because I don't know any other way!!) - basically I am converting the picture to a given size using a set density using convert and then concatenating the two using montage.
Here is part of my script:
Code:
Don't worry too much about the case statement at the end - that is just to be able to select to print either A, B or A and B.
The issue with this is that is doesn't work great if the aspect ratio is not maintained perfectly and also, it loses quite a lot of quality on the print.
I have a very old windows app which I wrote years back in VB (o dear! ) which does the same thing and the quality is fine (I am running it through wine). I want it to be command line though because I want to run it as part of other scripts etc.

I am trying to do a find/grep/wc command to find matching files, print the filename and then the word count of a specific pattern per file. Here is my best (non-working) attempt so far:
wc `find . ( -name "*.as" -o -name "*.mxml" ) -exec grep -H HeightResizableList {}` ;
Is there a way to specify to find that I only want text files (and not binary files)? Grep has an option to exclude binary files, so I thought find probably has a similar feature, but I've been unable to find it.

Anyway in the Kpackagemanager I removed the pulseaudio client (and its dependencies) and it messed up my system a bit. I don't really mind but all I need is to get my files from my home folder off my hdd to an external through usb 2.0. When Kubuntu 9.10 boots now all it is is a command terminal basically and I don't know the specific commands to get the files. Or if I need to reinstall something so that it boots up with a graphical looking UI again.

I can't find it with the diff command, as it says everything is common....meaning, I think, everything matches up. Yet my system monitor sees my primary drive as being 85% full and my backup (the same size drive) being 99+% filled!
Is there a linux command that would search through my file structure and list all the locations of any links? And is a "link" the only thing that would create a situation like this? P.S. That I know of, I didn't create any links. Whatever it was, seems to have started yesterday.
