Namespace KShell |

\namespace KShell Emulates some basic system shell functionality. See also KStringHandler |

Quotes and joins args together according to system shell rules.
If the output is fed back into splitArgs(), the AbortOnMeta flag needs to be used on Windows. On *NIX, no such requirement exists. See quoteArg() for more info. args - a list of strings to quote and join Returns a command suitable for shell execution |

Quotes arg according to system shell rules.
This function can be used to quote an argument string such that the shell processes it properly. This is e.g. necessary for user-provided file names which may contain spaces or quotes. It also prevents expansion of wild cards and environment variables. On *NIX, the output is POSIX shell compliant. On Windows, it is compliant with the argument splitting code of the Microsoft C runtime and the cmd shell used together. Occurrences of the percent sign are replaced with \%PERCENT_SIGN% to prevent spurious variable expansion; related KDE functions are prepared for this. arg - the argument to quote Returns the quoted argument |

Splits cmd according to system shell word splitting and quoting rules.
Can optionally perform tilde expansion and/or abort if it finds shell
meta characters it cannot process.
On *NIX the behavior is based on the POSIX shell and bash: - Whitespace splits tokens - The backslash quotes the following character - A string enclosed in single quotes is not split. No shell meta characters are interpreted. - A string enclosed in double quotes is not split. Within the string, the backslash quotes shell meta characters - if it is followed by a "meaningless" character, the backslash is output verbatim. - A string enclosed in $'' is not split. Within the string, the backslash has a similar meaning to the one in C strings. Consult the bash manual for more information. On Windows, the behavior is defined by the Microsoft C runtime. Qt and many other implementations comply with this standard, but many do not. - Whitespace splits tokens - A string enclosed in double quotes is not split - 2N double quotes within a quoted string yield N literal quotes. This is not documented on MSDN. - Backslashes have special semantics iff they are followed by a double quote: - 2N backslashes + double quote => N backslashes and begin/end quoting - 2N+1 backslashes + double quote => N backslashes + literal quote If AbortOnMeta is used on Windows, this function applies cmd shell semantics before proceeding with word splitting: - Cmd ignores all special chars between double quotes. Note that the quotes are not removed at this stage - the tokenization rules described above still apply. - The circumflex is the escape char for everything including itself. cmd - the command to split flags - operation flags, see Option err - if not NULL, a status code will be stored at the pointer target, see Errors Returns a list of unquoted words or an empty list if an error occurred |

Performs tilde expansion on path. Interprets "~/path" and
"~user/path". If the path starts with an escaped tilde ("\~" on UNIX,
"^~" on Windows), the escape char is removed and the path is returned
as is.
path - the path to tilde-expand Returns the expanded path |
