Hi All,
I want to run simple UNIX commands like
1) ls-ltr |grep <file name>
2) renaming of a file (mv <old file name> <new file name>)
3) telnet to a remote server (telnet <server IP)
from a JSP. Is there any ay by which i can do this? If so can i have some some sample codes for reference related to this? Any kind of help will be greatly appriciated.
Thanks in advance.>
If you REALLY want to use unix commands (or other underlying operating system and lose all portability) you use Runtime.exec
A very useful article on it:
http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html
However everything you have mentioned is possible to do in Java using the libraries.
1) ls-ltr | grep <file name>
File dir = "[directory to search]";
File[] fileList = dir.listFiles( [use a filename filter here if you want])
2) Again in the java.io package take a look at the method: File.renameTo
3) use the java.net classes, or a library for telnet
I see no reason to use unix commands when there is a relatively straight-forward java equivalent.
