If you are a power user you probably use old DOS or new Win32 programs designed to be run from the command line where the corresponding options are indicated. To start with, many file maintenance jobs are far easier when using command line utilities and batch files. The "user-friendly" way to do many simple tasks (comparing two directories or copying to the disk the relevant modified files of you current programming task, for instance) is boring and error prone. Unix-like filters also are still very useful. Any advanced user has a lot of command line programs in her system, but if you do not use them very often it is not always easy to remember the right option to do something. Cmd Line Shell is designed to be a shell for any command line program. · It provides a common, easily configurable, GUI look to any program which takes its options from the command line. · It will help you to prepare the command line and launch the external program. (You may also copy the command line to use it, say, form a batch file.) · You do not have to remember the syntax: the available options and their use are displayed. · You may easily search through your system for the input and output files. · Your favorite options may be set as new default. This program is designed to be used, for instance, with · the Console utilities by the same author, · the PostScript utilities included, for instance, in the excellent free implementation of TeX by Christian Schenk: MiKTeX 1.07, which is available from CTAN mirrors (ftp://ftp.tex.ac.uk/tex-archive/systems/win32/miktex/ and ftp://ftp.dante.de/tex-archive/systems/win32/miktex), · the epstool which comes with the last release of Ghostscript and GSview ( http://www.cs.wisc.edu/~ghost/), · many GNU utilities. The Definition Files (where the interface is defined) for many of these programs are provided (though you might need to change a line to specify the directory where your copy of each program is located).
