Building command line parameters of arbitrary length
I couldn't find an existing thread that addressed this question, so hopefully this isn't redundant with anything previously posted. Here goes:
I am writing a C-Shell script that runs a program that takes an arbitrary number of parameters:
myprog -a file1 \
-b file2 \
-c file3 ... \
-n fileN \
-operation "a+b+c+...+n"
The files on which myprog operates are in subdirectories: 01/01.ext, 02/02.ext, ... etc.
Since the filenames happen to match the directory names, I would like to be able to pass the script an arbitrary number of directories (in practice, there will be fewer than 26, so there is no concern with running out of "-x" tags). The script would then construct the argument list for myprog so that
myscript.sh 01 02 03 ... 12
would expand into:
myprog -a 01/01.ext -b 02/02.ext ... -k 11/11.ext -l 12/12.ext \
-operation "a+b+c+...+k+l"
Is there a straightforward way to do this?

dh_installdeb
DH_INSTALLDEB(1) Debhelper DH_INSTALLDEB(1)
NAME
dh_installdeb - install files into the DEBIAN directory
SYNOPSIS
dh_installdeb [debhelperoptions]
DESCRIPTION
dh_installdeb is a debhelper program that is responsible for installing files into the DEBIAN directories in package build directories with
the correct permissions.
FILES
package.postinst
package.preinst
package.postrm
package.prerm
These maintainer scripts are installed into the DEBIAN directory.
Inside the scripts, the token #DEBHELPER# is replaced with shell script snippets generated by other debhelper commands.
package.triggers
package.shlibs
These control files are installed into the DEBIAN directory.
Note that package.shlibs is only installed in compat level 9 and earlier. In compat 10, please use dh_makeshlibs(1).
package.conffiles
This control file will be installed into the DEBIAN directory.
In v3 compatibility mode and higher, all files in the etc/ directory in a package will automatically be flagged as conffiles by this
program, so there is no need to list them manually here.
package.maintscript
Lines in this file correspond to dpkg-maintscript-helper(1) commands and parameters. However, the "maint-script-parameters" should not
be included as debhelper will add those automatically.
Example:
# Correct
rm_conffile /etc/obsolete.conf 0.2~ foo
# INCORRECT
rm_conffile /etc/obsolete.conf 0.2~ foo -- "$@"
In compat 10 or later, any shell metacharacters will be escaped, so arbitrary shell code cannot be inserted here. For example, a line
such as "mv_conffile /etc/oldconffile /etc/newconffile" will insert maintainer script snippets into all maintainer scripts sufficient
to move that conffile.
It was also the intention to escape shell metacharacters in previous compat levels. However, it did not work properly and as such it
was possible to embed arbitrary shell code in earlier compat levels.
The dh_installdeb tool will do some basic validation of some of the commands listed in this file to catch common mistakes. The
validation is enabled as a warning since compat 10 and as a hard error in compat 12.
