You sholdn't need to use bash directly - simply use the 'shell' feature
on each file.
Of course, you could do just the same by putting all the commands into a
file, and then running it from bash if that was preferable :-)
Here's a fragment of a script I use to convert jpeg files (for different
This assumes that it starts in a folder full of files, and creates a
subfolder of resized files.
(And it deals with strangely named files that caused problems for
renaming the file
using convert (part of ImageMagick)
renaming the files back again.
I should probably have figured out all the naming / escaping needed -
but I was in a hurry :-)
create folder "width400"
repeat for each line L in tFiles
put "Converting" && L & "<br>" & CR after tOutput
-- deal with difficult file names
put L into K
-- e.g. replace "&" with "XXX" in K
rename file L to K
if not file_exists("width400", L) then
put "convert " & K & " -resize 400x400\> " & "width400/" & K
put "do " && tCmd && the result & "<br>" & CR after tOutput
set the defaultfolder to "width400"
rename file K to L
set the defaultfolder to ".."
rename file K to L
