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!

xzdiff
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.
