cp not dealing with variable properly? please help
I am having trouble with a script that is supposed to :
a)take all the jpg pictures in a given directory/parameter and create thumbnails of it in a directory on the desktop.
e.g
from /here/are/the/files.jpg to ~/Desktop/parser-the/files.png
this is my script: all the individual parts work but it falls apart when i put them together any help would be appreciated
Code:
for picturesource in $(ls ${1}/*.[jJ][pP][gG])
do
echo this is the picturesource $picturesource;
destination=~/Desktop/parser-"${picturesource}";
echo this is the destination $destination;
/bin/cp -Rf ${picturesource} ${destination} && echo cp done ;
basenames=`basename ${destination}`;
echo this is basename $basenames;
echo eval="convert -thumbnail 137 $picturesource ${destination}.png" && echo eval and it goes here $destination;
ls ~/Desktop/parser* && echo now listing files in the folder
sleep 1
done
Heres the output:
Code:
this is the picturesource test/hdgef.jpg
this is the destination /home/arbutt1/Desktop/parser-test/hdgef.jpg
/bin/cp: cannot create regular file `/home/arbutt1/Desktop/parser-test/hdgef.jpg': No such file or directory
this is basename hdgef.jpg
eval=convert -thumbnail 137 test/hdgef.jpg /home/arbutt1/Desktop/parser-test/hdgef.jpg.png
eval and it goes here /home/arbutt1/Desktop/parser-test/hdgef.jpg
/home/arbutt1/Desktop/parser-
now listing files in the folder
any help would be extremely appreciated

OGGTHUMB(1) User Manuals OGGTHUMB(1)NAME
oggThumb - creates thumbnails from an ogg video file
SYNOPSIS
oggThumb [options] file1.ogv [ file2.ogv [ file3.ogv [...] ] ]
DESCRIPTION
oggThumb creates Thumbnails from one or more ogg video files, at a given time position or a given frame number. It is also possible to cre-
ate a series of thumbnails at different time or frame positions. The pictures can be created in JPG or PNG format and can be resized to any
given size.
The default naming of each thumbnail series follows the following rule:
<filename_without_extension>_x.<picture_extension>
Where x starts with 0 and is incremented with every created thumbnail. So the thumbnails are successivly numbered by the appearence order.
This is even valid, if time positions and frame numbers are mixed.
OPTIONS -t Time at which a thumbnail should be created. More than one thumbnail time can be concatenated by commas. The times can be set by
integer or floating point values in seconds. If the time is not exactly matching, the next frame is used. The times don't have to be
sorted incrementally.
Example: -t 12.4,14.157,13.23
-f Number of a frame that should be created as a thumbnail. More than one thumbnail frame can be concatenated by commas. The frame num-
bers must be an integers. The frame numbers don't have to be sorted incrementally.
Example: -f 12000,13000,11000
-s Picture output size. The thumbnail is created in the size given as <width>x<height>. If you want to include the thumbnails into
your webpage and you need to have a fixed width but dynamic height, you can set the dynamic axis to 0. So the aspect ratio of the
video frame is kept. This is the same for setting width or height to 0.
Example: -s 0x100
-o Output format. This can be png or jpg. The default is jpg.
Example: -o png
-n Alternative thumbnail picture name. The % can be used within the name to indicate the counter placeholder.
In case of more than one video file, the counter continuous throughout the different videos, so that the pictures are not overwrit-
ten.
If the name has an extension. This extension is used to identify the output picture format.
Example: -n myNo_%_thumb
EXAMPLE
oggThumb -t 10.3,22.4,31.9,43.4,59.4 -f 1200 -s 0x100 myFile.ogv
oggThumb -f 200,400,300,100 -t 3.54 -n %_thumb.png myfile.ogv mysecondfile.ogv
