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.
