A simple Unix shell utility to save cleaned-up man pages as text (Bash)

2017-03-25T14:12:25-07:00

Bash recipe 580766 by Vasudev Ram (bash, documentation, man, script, shell, utilities, utility).

It's a shell script that lets you save the man pages for one or more Unix commands, system calls or other topics, to text files, after cleaning up the man command output to remove formatting meant for emphasis, printing, etc.

A utility like Unix seq (command-line), in Python (Python)

2017-01-08T17:48:57-08:00

Python recipe 580744 by Vasudev Ram (bash, command, commandline, linux, script, seq, sequence, shell, unix, utilities, utility).

This recipe shows how to create a utility like Unix seq (command-line), in Python. seq is described here:

https://en.wikipedia.org/wiki/Seq_(Unix)

but briefly, it is a command-line utility that takes 1 to 3 arguments (some being optional), the start, stop and step, and prints numbers from the start value to the stop value, on standard output. So seq has many uses in bigger commands or scripts; a common category of use is to quickly generate multiple filenames or other strings that contain numbers in them, for exhaustive testing, load testing or other purposes. A similar command called jot is found on some Unix systems.

This recipe does not try to be exactly the same in functionality as seq. It has some differences. However the core functionality of generating integer sequences is the same (but without steps other than 1 for the range).

More details and sample output are here:

The code is below.

Trap KeyboardInterrupt and EOFError for graceful program termination (Python)

2016-11-13T20:17:03-08:00

Python recipe 580718 by Vasudev Ram (ascii, error, exception, handler, shutdown, terminate, utilities, utility).

This recipe shows how to trap the KeyboardInterrupt and EOFError Python exceptions so that they do not crash your program. As a vehicle to show this, it uses a small Python utility that shows the ASCII code for any ASCII character you type.

2016-05-22T16:45:52-07:00

Python recipe 580663 by FB36 (image, images, utilities, utility). Revision 2.

Image resizer/converter command-line utility.

FileSpec: Set it, forget it, reuse it (Python)

2016-03-08T05:49:16-08:00

Python recipe 580618 by Jack Trainor (filename, utilities).

Python provides good utilities for transforming filenames, but they are tedious to use and clutter up the source code.

FileSpec offers one-stop shopping to convert a file path to every component you might want to know, reuse, or transform.

A UNIX-like "which" command for Python (Python)

2015-03-20T19:23:45-07:00

Python recipe 579035 by Vasudev Ram (bash, commandline, commands, linux, shell, unix, utilities, which).

UNIX users are familiar with the which command. Given an argument called name, it checks the system PATH environment variable, to see whether that name exists (as a file) in any of the directories specified in the PATH. (The directories in the PATH are colon-separated on UNIX and semicolon-separated on Windows.)

This recipe shows how to write a minimal which command in Python. It has been tested on Windows.

Shortcut Utility (Python)

2015-03-29T20:45:57-07:00

Python recipe 579041 by FB36 (desktop, directories, directory, file, files, tkinter, ui, utilities, utility).

I dislike filling my desktop with shortcut icons in Windows. This code enables creating shortcuts in a CSV file.

Create module dependency graph (Python)

2010-05-07T11:29:03-07:00

Python recipe 577222 by Noufal Ibrahim (dependecies, graphs, utilities).

The following snippet will dump the module dependencies in a format that can be interpreted by the dot program distributed along with graphviz. You can use it like below to see the dependency graph for the asynchat module for example. (the program is saved as grapher.py)

python grapher.py asynchat | dot -Tpng | display
