Antwort: Re: Executing unix command ( such as ls ) from the jslibYou can start a local server that's listening to a socket and redirect stdout to that socket with the help of netcat

Re: Antwort: Re: Executing unix command ( such as ls ) from the jslibI started sever its working fine...with command line...
Now I made a c program which do system(ls | nc localhost 6669); The above statement is working fine... But when I do, system( ls | myprog | nc localhost 6669) ; myprog is in the bash file PATH of my shell....but here the system command does not find myprog path......means it is not including the PATH of the bash of shell...So After lot of search also I cannot able to debug this error.... So , how to include shell enviroment to my program..Is there anyway of doing that or any other method by which I am able to do such stuff? Secondly,,,,.when I use var file = new File("/home/pawan/text.txt"). It creates file named test.txt in home of user pawan.... function createFile() { jslib.init(this); include (jslib_file); var file = new File("test.txt"); file.open("w"); file.write("This is a first file created by browser\n"); file.close(); } This program I am using to create file ...but it does not create file..I don't know y ...May be its creating the file from where firefox is invoked... But how to create file in my chrome://somename/content/ I want to create file in this folder.... Thanks in advance, Pawan Kumar

Also, in most cases "chrome://somename/content" is a mapped resource that points to a jar archive and is not a file on the filesystem. Usually for files you want to create and write to, you would place them in the mozilla/firefox profile dir which is a place you have permission to write to. --pete -- Pete Collins - Founder, Mozdev Group Inc. www.mozdevgroup.com Mozilla Software Development Solutions tel: 1-719-302-5811 fax: 1-719-302-5813 _______________________________________________ Jslib mailing list Jslib@... https://www.mozdev.org/mailman/listinfo/jslib |
