Power Storing cutted filenames into variable
Hi,
I'd like to write a script which works on various files file1.jpg, file2.jpg ..... These files are splitted and their names are something like file[1-9]_[1-9].XXX. I'd like to merge them and convert them at some moment again in file[1-9].XXX also
file1_1.jpg file1_2.jpg ... >file1.pdf
file2_1.txt file2_2.txt ... >file2.pdf

I'd use for loop and I need there to specify the variable - the first part of the filename. I'd write
for file in *[#-#]_*.jpg
do for i in {#-#}
do convert .....
done
done

I don't know how many files I'd use for the conversion in advance because it varies, I even't don't know the names file1, file2 and their amount. I'd need to get it know from the folder, somehow count the amount of file1_xxx files and the amount of file[1-9] files.
How can I do that?
Thank you very much!

lzcmp

XZDIFF(1)							     XZ Utils								 XZDIFF(1)

NAME

       xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files

SYNOPSIS

       xzcmp [cmp_options] file1 [file2]
       xzdiff [diff_options] file1 [file2]
       lzcmp [cmp_options] file1 [file2]
       lzdiff [diff_options] file1 [file2]

DESCRIPTION

       xzcmp  and  xzdiff  invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), bzip2(1), or lzop(1).  All options specified
       are passed directly to cmp(1) or diff(1).  If only one file is specified, then the files compared are file1 (which must have a suffix of  a
       supported  compression format) and file1 from which the compression format suffix has been stripped.  If two files are specified, then they
       are uncompressed if necessary and fed to cmp(1) or diff(1).  The exit status from cmp(1) or diff(1) is preserved.

       The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils.

SEE ALSO

       cmp(1), diff(1), xz(1), gzip(1), bzip2(1), lzop(1), zdiff(1)

BUGS

       Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified.
