Even after correcting that to

Code:
for i in `ls -1 test`  ## backticks, not apostrophes

it is still the wrong way to loop through files. Not only is ls unnecessary, but it will cause the script to fail if any filenames contain spaces. (Also, the -1 is unnecessary since the output is not going to a terminal.)

The correct way is:

Code:
for i in test/*

WRAP-AND-SORT(1)                                              General Commands Manual                                             WRAP-AND-SORT(1)

NAME

       wrap-and-sort - wrap long lines and sort items in Debian packaging files

SYNOPSIS

       wrap-and-sort [options]

DESCRIPTION

       wrap-and-sort  wraps the package lists in Debian control files. By default the lists will only split into multiple lines if the entries are
       longer than 80 characters. wrap-and-sort sorts the package lists in Debian control files and all .install files. Beside that  wrap-and-sort
       removes trailing spaces in these files.

       This  script should be run in the root of a Debian package tree. It searches for control, control.in, copyright, copyright.in, install, and
       *.install in the debian directory.

OPTIONS

       -h, --help
              Show this help message and exit.

       -a, --wrap-always
              Wrap all package lists in the Debian control file even if the entries are shorter than 80 characters and could fit in one line line.

       -s, --short-indent
              Only indent wrapped lines by one space (default is in-line with the field name).

       -b, --sort-binary-packages
              Sort binary package paragraphs by name.

       -k, --keep-first
              When sorting binary package paragraphs, leave the first one at the top.  Unqualified debhelper(7) configuration files are applied to
              the first package.

       -n, --no-cleanup
              Do not remove trailing whitespaces.

       -d path, --debian-directory=path
              Location of the debian directory (default: ./debian).

       -f file, --file=file
              Wrap  and sort only the specified file.  You can specify this parameter multiple times.  All supported files will be processed if no
              files are specified.

       -v, --verbose
              Print all files that are touched.
