Hi,

I am executing df -k command from java using below code snippet.

Process proc = Runtime.getRuntime().exec("df -k " + path );

Its working fine when i execute only once. At the same if i execute for multiple times its failed. proc.exitValue is returning 1.

Could anyone please let me know if i need to do anything more here.

Regards,
Riyaz

depending on the distro..

do
which df

on the command line should give you the full path to df.

ie.
CentOS
/bin/df

Then add your full path to your java command.

Process proc = Runtime.getRuntime().exec("/bin/df -k /root" );

ideally your java code should check which distro / OS it is running agenst and add the correct location of df, uname -a is your friend for this.
