General :: Write A Shell Script Which Will Read The Directory Path As Input From User?

Nov 28, 2010

I am new to writing shell scripts. So, please bare with me. I am currently trying to write a shell script which will read the directory path as input from user and will traverse the Dir tree to find all available audio and video files. I have tried to write as much as I could but I don't know where I am making mistake as I get some files to be audio file which are actully tar balls. On the second note there are some files which video but script shows them to be audio. And, some video files are completely skipped. I am giving the shell script below so that you can see. I am using two external files as source which I am attaching.

Code:

#!/bin/bash
#Let's load the extensions that we want to search for
vdExt=$(cat vdExtList)
adExt=$(cat adExtList)

General :: Stripping EXIF Metadata + Preserving Of The Original Date

Feb 23, 2011

I would like to remove almost all of the Privacy Evading data that a digital camera is generating, such as EXIF DATA. EXIF DATA: Camera Brand, Camera Model, Date taken, Exposure Time, Flash Fired, Focal Length, Location (if you are using iPhone with categorization by location, if enabled), Metering Mode, etc.

May you, please, write a script which does that job for multiple files?Exiv2 seem to reduce more weight than Jhead so I'll use the command exiv2.That's, generally, what I want the script to do:Retrieve the (Modified) date of a file.

General :: Copying Jpegs Recursively While Preserving The Directory Structure?

Aug 9, 2010

So I have a bunch of directories:

dir1
dir2
dir3
etc.

which themselves all contain subdirectories:

dir1subdir1subdir2etc.and at the lowest level they contain all of these jpegs that I need. The problem is that I only need some of them. They're named like this:

pic1.jpg
pic1_med.jpg
pic1_small.jpg
pic2.jpg
pic2_med.jpg
etc.

I want to just grab the ones without the size suffix and copy them all to another set of folders, while preserving the directory structure. The numbering all starts at 1 for each low level subdirectory, so I think that the directory structure is the only way to not get them mixed up.

I know that cp has a recursive option -r but how do I just extract the ones without the underscore? And then how do I preserve the directory structure when I move them over?

Ubuntu :: Read Not Allowing Operators In Shell Scripts

Dec 26, 2010

I'm trying to write a small application controlling spotify, running under wine, that I can run from my desktop computer and use via SSH on my mobile phone, and so far I've been quite successful. At least until just recently, when I tried to use the read command to read a single key-press on my phone, and use that input instead of having to type the number for item in the menu I've created. I tried to simply use the read command to silently listen to one key-press and output it to the variable opt. To do this I tried:

read -s -n1 opt

When I ran this in a shell-script this I got:

read: 1: Illegal option -s

Seeing this, I tried to remove the -s operator, which left me with:

read: 1: Illegal option -n

I decided to remove all operators and echo the variable opt, leaving me with:

read opt
echo "$opt"

Which worked as expected. It echoed the key that I had pressed. I moved over to my terminal window and tried the read command from there, and it did exactly what it should. It silently recorded one key-press to the variable opt.

why isn't read working with operators in shell scripts?

Slackware :: Preserving Feh's LXDE Wallpaper Between Sessions?

Typing 'feh --bg-scale /usr/share/lxde/wallpapers/lxde_blue.jpg' immediately gives me what I want, but next login it's gone again. I know I have to put an entry in ~/home/pargoo/.config/openbox/autostart.sh but nothing works. So far I've tried:

eval `cat $HOME/.fehbg` &
eval `cat $HOME/pargoo/.fehbg` &
eval `cat ~/.fehbg` &
