Shell Programming and Scripting

I'm making a shell script to:

-copy directories to a new location
-perform conversions on the files within the copied directories
-move the newly created files to a new directory

Please see my super basic script and notes below... and thank you thank you thank you in advance !!

Code:

#created 9/4, KZ

subjid=SWJNaudio04  #subject info 
value=0* 


cd /data2/SWJN/Originals/${subjid}/bold/
cp -r 0* ../../../NIFTI/${subjid}/bold

#these first two lines (above) copy all directories starting with 0 (012, 014, 028, etc.) to the desired new location

cd ../../../NIFTI/${subjid}/bold

#below is where my problem is. mri_convert uses the following format: mri_convert -options /desired/input/path/and/filename /desired/output/path/filename. my problem is that within each /${subjid}/bold/ directory, there are multiple folders (all starting with '0') each containing multiple bshort and hdr files (all starting with 'f_0') and I would like to run the converter/repeat the conversion for every bshort file in each of these directories. I can't just type the actual directory and file numbers because they will differ for each subject. I would ideally like a way to select the numbers from each directory and filename so that the same numbers can be used in the output. I tried to use 0* and f_0*, respectively, to run the converter for all files beginning with 'f_0' in all directories beginning with '0' but this obviously will not work lol

Code:

for f in ${value} ; do mri_convert -it bshort -ot nii /data2/SWJN/Original/${subjid}/bold/${value}/f_${value}.bshort /data2/SWJN/NIFTI/${subjid}/bold/${subjid}_${value}



mkdir NIFTI
mv  *.nii  /NIFTI/
#this will move the newly created .nii files to new directory

man find, see -exec option

Alternatively use find combined with xargs.
