CURLY(1L)                                                            CURLY(1L)

NAME
       curly, uncurly - expand or build csh-like path expressions

SYNOPSIS
       curly [expressions]
       uncurly [-depth] [names]

DESCRIPTION
       Curly expands a csh(1) curly brace expression.  Such an expression is
       of the form

            prefix{E1,E2,E3}suffix

       which expands to

            prefixE1suffix
            prefixE2suffix
            prefixE3suffix

       any subexpressions are also expanded.

       Uncurly compresses a given path expression into a minimal curly
       expression.  Thus

            uncurly ab.c ab.h de.c de.h ef.c ef.h

       produces this output

            {ab,de,ef}.{c,h}

       Either product will run in a filter mode if no arguments are provided.

OPTIONS
       Both programs take the standard help (-h) and version (-V) options.  In
       addition uncurly takes an integer -depth option to limit the depth of
       the compression search.

EXAMPLES
       cd; find . -depth -print | uncurly >/tmp/files.u
              save a compressed list of the files in my home directory in
              /tmp/files.u.

       curly </tmp/files.u | xargs my-tool
              Use xargs to run my-tool on each of the saved names in
              /tmp/files.u.

       sort /tmp/mylist | uncurly -2 >/tmp/mylist.u
              Compress a sorted list of the names in /tmp/mylist, but limit
              the compression to 2 nested levels of curlies.

BUGS
       Files with curly braces in their names are problems.
