Detailed Description

This class is similar to KProcess. The only difference is that KShellProcess runs the specified executable through a UN*X shell so that standard shell mechanisms like wildcard matching, use of pipes and environment variable expansion will work.

For example, you could run commands like the following through KShellProcess:


   ls ~/HOME/ *.lyx | sort | uniq |wc -l

KShellProcess tries really hard to find a valid executable shell. Here is the algorithm used for finding an executable shell:

 KShellProcess (const char *shellname=0)

KShellProcess

Constructor

By specifying the name of a shell (like "/bin/bash") you can override the mechanism for finding a valid shell as described in the detailed description of this class.

 ~KShellProcess ()

~KShellProcess

Descructor.

bool  start (RunMode runmode = NotifyOnExit, Communication comm = NoCommunication)

start

[virtual]

Starts up the process. -- For a detailed description have a look at the "start" member function and the detailed description of KProcess .

Reimplemented from KProcess.

QString  quote (const QString &arg)

quote

[static]

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 wildcards and environment variables.
