how to execute a unix shell script from a java program
Hi All,
well , i am facing this problem.. i have tried a few sample codes but there isn't any solution . could anyone please give a sample code as of how to do this...
Please see the below details...and read the details carefully.
I have written some code, logic is
1)from UI we will get one file on window
2)from window that file will save on server i.e on /home/user01/trial1/csvfile.txt (This is successfully downloaded on the server)
3)that file we are passing to the script name-"omsSB.sh"
and output will save in csvfileout.txt
In below code everytnig is fine .From UI I am able to pass the tuple and also fetch the output file but iam unable to execute the omsSb.sh script
Question--> SCRIPT_NAME =./omsSb.sh is it the correct command or i need to right--- /home/user01/trial1/omsSb.sh. tried some of these like but script is not running.
This below code i have write in eclipse properties file , where i can mentioen the all the details of server.
This suppose that you already are in the directory hosting that script
It also suppose that your user is granted (at least) to read that script (if you want to run it in the way mentionned above, you also must have execution right on it)
It also suppose that your script has the execution right (chmod +x yourscript).
If the execution right are not set for your file you can try to run it like :
If you want to execute shell script or any system command then below code may help you.
Code:
try {
Process p = Runtime.getRuntime().exec("uname -a");
// you can pass the system command or a script to exec command. here i used uname -a system command
BufferedReader stdInput = new BufferedReader(new
InputStreamReader(p.getInputStream()));
BufferedReader stdError = new BufferedReader(new
InputStreamReader(p.getErrorStream()));
// read the output from the command
String s="";
while ((s = stdInput.readLine()) != null) {
System.out.println("Std OUT: "+s);
}
while ((s = stdError.readLine()) != null) {
System.out.println("Std ERROR : "+s);
}
} catch (IOException e) {
e.printStackTrace();
}
