Full Discussion: Print the name of files in the directory using Perl

A one-liner using only Perl (unlike the others presented so far):
Code:
perl -e 'print join "\n",grep { -f } <*>'

Explanation:
  • <*> is a glob that expands to all entries in the current directory
  • grep is a function that works pretty much like the shell utility. It expects a statement block returning true or false values on the parameters.
  • The -f is a shorthand for testing if a parameter (here it's the anonymous automatic variable $_) is a regular file or not
  • And finally it all gets nicely formatted by join and printed

autoreconf2.13

AUTORECONF(1)						      General Commands Manual						     AUTORECONF(1)

NAME

       autoreconf2.13 - update configure scripts

SYNOPSIS

       autoreconf2.13 [ --help | -h ] [ --force | -f ] [ --localdir=dir | -l dir ] [ --macrodir=dir | -m dir ] [ --verbose ] [ --version ]

DESCRIPTION

       If  you	have  a lot of Autoconf-generated configure scripts, the autoreconf2.13 program can save you some work.  It runs autoconf2.13 (and
       autoheader2.13, where appropriate) repeatedly to remake the Autoconf configure scripts and configuration header templates in the  directory
       tree rooted at the current directory.  By default, it only remakes those files that are older than their configure.in or (if present) aclo-
       cal.m4.	Since autoheader2.13 does not change the timestamp of its output file if the file wouldn't be changing, this  is  not  necessarily
       the minimum amount of work.  If you install a new version of Autoconf, you can make autoreconf2.13 remake all of the files by giving it the
       --force option.

       If you give autoreconf2.13 the --macrodir=DIR or --localdir=DIR options, it passes them down to autoconf2.13 and autoheader2.13 (with rela-
       tive paths adjusted properly).

       autoreconf2.13 does not support having, in the same directory tree, both directories that are parts of a larger package (sharing aclocal.m4
       and acconfig.h), and directories that are independent packages (each with their own aclocal.m4 and acconfig.h).	It assumes that  they  are
       all  part  of the same package, if you use --localdir, or that each directory is a separate package, if you don't use it.  This restriction
       may be removed in the future.

       autoreconf2.13 accepts the following options:

       --help

       -h     Print a summary of the command line options and exit.

       --force

       -f     Remake even configure scripts and configuration headers that are newer than their input files (configure.in and, if  present,  aclo-
	      cal.m4).

       --localdir=DIR

       -l DIR Look for the package file aclocal.m4 in directory DIR instead of in the current directory.

       --macrodir=DIR

       -m DIR Look  for  the  installed  macro files in directory DIR.	You can also set the AC_MACRODIR environment variable to a directory; this
	      option overrides the environment variable.

       --verbose
	      Print the name of each directory where autoreconf2.13 runs autoconf2.13 (and autoheader2.13, if appropriate).

       --version
	      Print the version number of Autoconf and exit.
