Convenience functions for constructing shell commands

Latest release 20210316: Minor doc update.

Functions for safely constructing shell command lines from bare strings. Somewhat like the inverse of the shlex stdlib module.

As of Python 3.3 the function shlex.quote() does what quotestr() does.

As of Python 3.8 the function shlex.join() does what quotecmd() does.

Function main_shqstr(argv=None)

shqstr: emit shell-quoted form of the command line arguments.

Function quote(args)

Quote the supplied strings, return a list of the quoted strings.

As of Python 3.8 the function shlex.join() is available for this.

Function quotecmd(argv)

Quote strings, assemble into command string.

Function quotestr(s)

Quote a string for use on a shell command line.

As of Python 3.3 the function shlex.quote() is available for this.
